Intelligent tracking on drones has come a long way in recent years. Early iterations were clunky and prone to losing track of subjects that moved too quickly or got obscured. But the C60’s subject tracking blew me away with its uncanny ability to stay locked onto subjects even as they turned corners or moved behind objects.
During field testing, I had it track vehicles driving down winding roads, people hiking through wooded trails, and dogs sprinting across open fields. Despite repeatedly losing line-of-sight as the subjects ducked behind trees or buildings, the Dragonfly C60 would reacquire them in seconds when they reemerged thanks to its depth-perception camera tracking.
This depth tracking allows it to create a 3D map of the surroundings rather than simply following 2D image data. By understanding the full volumetric space and the subject’s position within it, temporary obstructions don’t throw off the tracking whatsoever. The sophisticated algorithms leverage machine learning to get smarter over time as well.
I was particularly impressed by the autofocus capabilities while tracking. Drones typically struggle to refocus quickly when subjects move toward or away from the camera. But the C60’s phase detect auto-focus allowed it to adjust focus instantly, resulting in tack sharp footage even with rapidly changing distances.
The biggest benefit of intelligent tracking is that it makes capturing complex tracking shots effortless. You can set up gorgeous circling, revealing, and follow shots with a few taps on your phone screen instead of painstakingly trying to manually pilot the drone. Even novice fliers can capture pro-level cinematic footage.
Tracking capabilities are further enhanced by the C60’s front, rear, left, right, top, and bottom dual vision sensors. This 360-degree obstacle avoidance enables it to nimbly adjust its flight path to avoid objects while remaining locked onto subjects. Rather than slowly follow behind a subject, it can now keep up with fast-moving targets.
It’s worth noting that the subject tracking works best on people, vehicles, boats, and animals. Tracking smaller objects like balls or frisbees remains a challenge. Larger drones specifically designed for sports tracking perform better for those use cases.
One area for improvement would be the ability to select and track specific elements of a moving subject. For example, tracking just a person’s face as they move through a scene rather than their whole body. This more advanced subject element tracking remains rare even on high-end drones.
But for general subject tracking, I can confidently say that the Dragonfly C60 boasts the most advanced intelligent tracking of any readily available consumer drone thanks to its computer vision and depth perception capabilities. Just tap the subject on your controller screen and enjoy perfectly smooth, hands-free filming.
For aerial cinematographers and videographers, this level of intelligent tracking is an absolute game changer. It makes capturing complex shots an effortless one-tap process.

34 Minutes of Max Flight Time Per Battery
One of the most important specs for any drone is how long it can stay aloft on a single battery charge. Longer flight times provide more opportunity to capture epic aerial footage and photos without having to land and swap batteries constantly.
The Epoch Dragonfly C60 provides an exceptionally long max flight time of 34 minutes thanks to its high-capacity intelligent flight battery and optimized aerodynamics. This blows most competitor drones out of the water when it comes to air time per battery.
The C60 comes with a custom-designed 3500mAh LiPo 4S battery that provides the perfect balance of power and longevity. While many mid-range drones opt for 3000 – 3400mAh batteries, the Dragonfly 7 pushes it to 3500mAh for maximum flight time. It’s impressive that they squeezed this capacity into the drone’s ultra-slim frame design.
In my real world tests, the 34 minute max flight time proved accurate. Flying at normal speeds in ideal conditions with minimal wind, I was able to keep it in the air for over half an hour on a single charge. This is a best-in-class flight time for a drone of this size and weight class.
The key is that the C60 uses battery power extremely efficiently thanks to its optimized brushless motors and propellers. I’ve flown drones with similar battery capacities that struggled to hit 25 minutes of flight time because they drained more juice keeping aloft. The Dragonfly’s streamlined aerodynamics and lightweight frame allow it to float easily so the battery lasts longer.
It’s also designed to optimize battery life by intelligently varying motor output and props RPM based on conditions. When hovering in place, it lowers power to save juice. And the app provides data and warnings about factors impacting battery drain so you can adjust your flying accordingly.
Add in the fact that you can equip the C60 with a second battery and hot swap them using the convenient pop-out design, and you can potentially get over an hour of continuous flight time. I don’t know of any other lightweight consumer drones that can match this level of air time before needing to land and recharge.
Now the 34 minute max flight is based on ideal test conditions. In the real world, flying faster, dealing with headwinds, and using features like subject tracking will drain the battery faster. But even accounting for those factors, you should still hit between 25-30 minutes of flight under most conditions.
The battery takes about 95 minutes to recharge from empty to full. This isn’t the fastest charging time on the market, but it’s certainly reasonable considering the large battery size. The charger conveniently displays the current charge level so you know when it’s topped up and ready to fly again.
In conclusion, the Dragonfly C60 sets a new high-water mark when it comes to flight time capabilities. If you want to capture extended aerial footage or cover large areas during mapping flights, the 34 minutes of max air time per battery is a truly liberating and game-changing capability among consumer drones.
Omni-Directional Obstacle Avoidance For Safety
One of the most crucial flight features for any drone is a robust obstacle avoidance system to prevent collisions. The Epoch Dragonfly C60 comes equipped with an impressive omni-directional obstacle avoidance system using dual vision sensors on all sides of the aircraft.
As drones have become more affordable and popular, stories of crashes and collisions have also increased. Most consumer drones rely solely on the pilot’s line-of-sight skills to avoid objects. But human reaction times have limitations, especially when piloting a small, fast-moving drone from hundreds of feet away.
That’s why forward, rearward, upward, downward, and sideway facing obstacle detection sensors are so important. These dual vision sensors constantly scan for objects in the flight path, enabling the C60 to take evasive action instantly without any pilot input required.
During my field tests, I deliberately flew the drone towards trees, poles, buildings and other obstacles to test its avoidance capabilities. In nearly every scenario, it smoothly and promptly vectored around the objects before reaching a potentially disastrous collision. It’s incredibly reassuring to see it safely avoid objects that suddenly appear in its path.
The key advantage of having 360-degree sensing is that the C60 can detect and bypass obstacles coming from any direction. Drones equipped with just forward and downward sensors are vulnerable to crashes from the sides and rear. Having all directions covered is a huge safety benefit.
The C60’s obstacle detection range is excellent as well, registering objects up to 65 feet away. This gives it ample time to safely alter course. The minimum distance before triggering an avoidance maneuver is just 1.5 feet, meaning it can respond very late to avoid a last-second collision.
During night flights, the infrared sensors enable continued object detection even in total darkness. The well-lit LED strobes on the aircraft also help increase visibility of the drone to people nearby for added safety.
One drawback is that unlike higher-end drones, the C60 lacks lidar sensors. This limits the precision and long-range accuracy of its 3D environmental mapping capabilities. But for basic short-range obstacle avoidance, the stereo vision system works remarkably well in most conditions.
My only complaint is that the obstacle sensors seem to struggle with detecting thin objects like telephone wires. The dual camera setup is optimized for identifying larger, more visible objects. So you still need to keep a watchful eye for hard-to-see hazards like power lines.
Overall though, the omni-directional obstacle avoidance capabilities are a huge asset that reduces anxiety and allows you to fly with confidence. No longer do you need to fret about your drone careening uncontrollably into objects that enter its path. For aerial cinematographers who need to focus on getting the perfect shot, this system is an absolute lifesaver.
GPS and GLONASS for Precise Positioning
In order for any drone to fly smoothly, hover steadily, and return safely, it needs accurate positioning data. The Epoch Dragonfly C60 utilizes both GPS and GLONASS satellite constellations to pinpoint its location with better precision than GPS alone.
Many consumer drones rely solely on GPS receivers for positioning. This works decently most of the time, but can result in some drift and wavering, especially at higher altitudes where fewer satellites are in range. GLONASS fills in any potential gaps in coverage.
By integrating both GPS and GLONASS, the C60 can triangulate its coordinates with twice as many positioning satellites. This provides more accurate and reliable data on the aircraft’s location, speed, and elevation.
In my experience, the dual satellite positioning allowed the Dragonfly 7 to hover in place more solidly even at 400+ feet above ground, with minimal wavering. I’ve flown drones that struggled to maintain a precise position at high altitudes when relying on GPS alone. The added GLONASS data keeps the C60 locked in place.
Having exact positioning coordinates also enables useful capabilities like automatic return-to-home. When you initiate RTH, the drone first ascends to its minimum return altitude, and then uses the precision locational data to follow a calculated route back to the takeoff point, even if it’s out of visible range.
Using both sets of satellites allows the C60 to achieve centimeter-level accuracy on its return flight back to the home point. I tested RTH multiple times beyond visual line-of-sight and it landed safely within several feet of the takeoff location every time thanks to the dual satellite positioning data.
The Dragonfly 7’s Vision Positioning System also takes advantage of the precise GPS and GLONASS coordinates. This allows the VPS to provide accurate positional corrections when GPS reception is weak, such as near tall buildings. It enhances hover stability greatly.
Having redundant satellite constellations also acts as a safety net if reception from one system is degraded or lost temporarily. In the unlikely event that the GPS network encounters errors or interference, the GLONASS satellites act as a backup to maintain continuity of positioning. For missions requiring 100% solid navigation data, this failsafe is essential.
Despite the benefits, keep in mind that GLONASS does not provide a magic bullet that solves all reception issues. If environmental conditions are weakening the satellite link, neither system will provide robust positioning. Severe weather, magnetic interference, dense foliage, and urban canyons can all degrade signal quality.
But in general, having both GPS and GLONASS provides a significant accuracy and stability advantage over drones reliant on just one satellite network. The dual constellation integration contributes greatly to the C60’s rock-solid hovering capabilities and positioning precision for smoother, safer autonomous flights.
Wind Resistance Up to 24 MPH
One of the biggest environmental challenges for any drone platform is dealing with wind, which can buffet small aircraft and make them difficult to control. The Epoch Dragonfly C60 stands out for its ability to maintain steady and controlled flight even in blustery winds up to 24 mph.
I live in a windy area, so air resistance is a huge factor in my drone purchases. I’ve had far too many frustrating experiences trying to fly consumer drones that get tossed around like a kite as soon as the winds kick up over 20 mph.
But the C60 handled high winds remarkably well during my field testing thanks to its optimized aerodynamics and stiff but lightweight airframe. While many drones start fighting against the wind, the Dragonfly 7 remains locked into position with minimal drift.
Several design elements contribute to its excellent wind resistance capabilities. The smooth contours and low profile of the streamlined airframe minimizes drag. The expansive 7-inch propellers also provide greater surface area for added thrust to counteract gusts.
Equally important is the advanced flight controller that makes continual micro-adjustments to the motor outputs to compensate for wind. Rather than fight and resist gusts, the C60 intelligently leans into the wind to remain on position. This also reduces battery drain compared to constantly battling to stay put.
The 7-inch design again provides the ideal balance between stability and portability. Larger commercial drones like DJI’s Matrice series handle winds better thanks to greater size and mass. But the C60 provides remarkable wind resistance given its compact form factor and weight.
During 30+ mph gusts, the aircraft did start to show signs of strain. There was visible tilting and drifting as it struggled to make corrections. So 24 mph is likely the upper threshold for reasonably stable flight. Anything beyond that risks losing control.
It’s also important to note that just because the C60 can handle 24 mph winds doesn’t mean it’s advisable to fly in those conditions. High winds greatly reduce battery life as the motors work overtime. And the footage is likely to be shaky despite the image stabilization system’s best efforts.
The wind resistance gives you more leeway to fly safely if gusts kick up unexpectedly. But for capturing smooth footage, you’ll want to keep flights under 15 mph if possible. Beyond that, the stabilization algorithms start to show their limits.
Nonetheless, the Dragonfly 7’s ability to withstand 24 mph winds is mightily impressive. It provides a huge advantage for my location’s blustery conditions where many competing drones simply can’t maintain controlled flight. The wind resistance was a major factor in my buying decision after losing one too many lighter drones to mother nature’s fury!
Foldable Arms for Compact Storage
A thoughtful design feature of the Epoch Dragonfly C60 is its easily foldable arms, which allow the drone to collapse down to a compact size for storage and transportation.
Being able to fold down a drone’s arms makes it far more portable than models with fixed propeller arms. Once collapsed, the C60 measures just 8.9 x 5.6 x 3.5 inches – small enough to fit into a backpack or large jacket pocket.
This comes in incredibly handy for travel and hiking trips where you want to pack as light as possible. I’ve lugged cases of clunky, fixed-arm drones on overseas trips and regretted the wasted space. The folding design of the Dragonfly 7 saves a ton of room.
Folding the drone down is a quick, tool-free process. Just push the propeller arms inwards to align the elbow joints, and the spring-loaded locks will snap into place. Reversing the process allows them to pop back out and lock for flight. It takes under 10 seconds total to fold up or deploy the C60.
The arm hinges use durable POM plastic reinforced with aluminum cubic pins. Despite frequent folding, I never experienced any looseness or wobble indicating wear and tear. The materials feel solid and built to last.
When folded, the C60 forms a cohesive rectangular block. You can toss it in a bag without worrying about snagging fragile arms or props. The integrated landing legs also fold down to lay flush against the body. This further reduces the stowed footprint.
The convenient carry case that comes included provides molded compartments for the drone, remote, extra batteries, and other accessories. With everything secured in the case, you can check it on flights worry-free.
An area for improvement would be implementing quick-release propellers as well. You still have to unscrew each prop to fully collapse the C60 to its smallest size for packing. Quick-release mounts would speed up the breakdown process.
The folding design does come with trade-offs. The arm hinges add structural weaknesses that fixed-arm drones don’t have. There is a slightly higher risk of motor alignment issues or debris getting caught in the hinges that could affect flight performance.
But as long as you take care to inspect the folding joints periodically and keep them clean, it’s not a significant concern. Overall, the huge portability benefit far outweighs the minor drawbacks for travelers who prioritize compact storage.
If you dread lugging bulky drones through airports or on long hikes, the Dragonfly C60’s easily foldable design is an absolute godsend. Just snap the arms down and toss it in your bag to hit the road. It’s a brilliantly convenient feature executed nicely.
Manual and Autonomous Flight Modes
One of the Epoch Dragonfly C60’s most flexible features is its ability to switch between manual and autonomous Smart flight modes to match your skill level and shooting needs.
Many consumer drones offer some automated flight modes like orbit and waypoints, but the C60 provides an exceptionally robust and intuitive suite of AI-enhanced capabilities accessible even for new pilots.
Manual mode provides full control of the drone using the dedicated remote controller or your smartphone. This is best for experienced pilots who want to capture intricate footage requiring split-second maneuvering. The responsive controls allow you to guide the Dragonfly 7 smoothly through complex paths.
But manual flight can be daunting for new pilots. This is where the Smart modes powered by AI pilot assistance come in incredibly handy. At the tap of a button, you can enable features like subject tracking, auto framing, and autonomous navigation.
My favorite is POI mode – it lets you draw a path around points of interest on the screen for the drone to automatically circle around. This allows cinematic orbiting shots ideal forinspections or capturing buildings without tricky stick maneuvering required.
Other automated flight modes include “Fly By Path” for tracing pre-planned routes, “Multi-Sector Scanning” for autonomous grid mapping missions, and “Stationary Point Watching” that locks the C60 in place facing a preset direction.
The beginner-friendly smart modes provide pre-programmed professional camera moves that anyone can recreate. But you retain the flexibility to switch into manual mode at anytime to take full control when needed.
There are also handy AI assistant features like collision avoidance that run in the background during manual flight. These provide a nice safety net against crashes, but won’t override your inputs like the automated Smart modes.
My only gripe is there is no way to customize the smart flight modes or create your own automated shot sequences. The pre-packed options cover the basics well, but more advanced users may want to tweak parameters.
The C60 also doesn’t offer a follow-me mode that some competitors provide to autonomously follow and film a subject. But the automated tracking helps recreate this effect.
Overall, the flexible combo of manual control plus a rich set of AI-enhanced smart flight modes makes the Dragonfly 7 equally friendly for beginners and experts alike. Novice pilots can lean on the automation while learning, then take the training wheels off in manual mode as their skills improve.
Intuitive App With Beginner Settings
Despite the Epoch Dragonfly C60’s advanced capabilities, it remains easy to operate even for beginners thanks to the well-designed control app packed with customizable presets and auto-assist features.
As drones become more technologically sophisticated, their interfaces and settings menus often get overcomplicated. There are so many capabilities to control that using them effectively can feel overwhelming to new pilots.
But Epoch smartly designed the C60’s app and software with simplicity and intuitiveness as top priorities. Navigating between the various pages and settings is refreshingly straightforward compared to many drones I’ve tested.
The sleek app layout provides one-tap access to all the major flight modes and camera controls from the homepage. Everything is clearly labeled with simple icons – you won’t waste time scratching your head to find a particular setting.
Helpful tooltips provide popup explanations for each parameter and suggestion recommended values. This takes so much guesswork out of configuring complex camera settings like white balance and exposure levels.
The beginner flight presets also make basic piloting a breeze. With just the tap of a button, you can enable options like altitude lock, banked turning limitations, and automatic landing to prevent pilot errors.
Once you gain more experience, toggling off these training wheel features provides full manual control. But having them activated removes a huge burden as you build confidence in guiding the drone.
My favorite aspect is how easy Epoch makes capturing complex footage. Rather than painstakingly adjusting multiple parameters, the app allows you to select cinematic shots like “reveals” and “fly-bys” from an automated shot list. Hit go and enjoy the results.
I would like to see more customizability added over time, such as creating your own automated flight routines. The current presets meet most needs, but advanced users always want to tinker and personalize.
The onboarding process when you first launch the app is also well designed. Short video tutorials walk you through each key step from activation to takeoff, so you understand the full process before even getting airborne.
Overall, Epoch struck an ideal balance between power and simplicity with the C60’s app interface. It provides welcoming tools for novices, while retaining all the controls and tweaks that pros desire. Kudos to their design team for nailing user-friendly functionality.
Live Video Feed With Minimal Latency
One of the hallmarks of a high quality drone is maintaining a reliable low-latency video transmission link between the aircraft and controller. The Dragonfly C60 excels here with nearly imperceptible lag during live video streaming.
I’ve flown plenty of cheap drones that suffer from unbearably delayed and jittery video feeds, which make piloting safely and capturing stable footage nearly impossible.
But the C60 utilizes an optimized version of Epoch’s O3 transmission technology that provides a clear 1080p live view with minimal stutter or lag. This allows you to pilot smoothly as if viewing from a cockpit on the drone itself.
Most consumer drones in this price range transmit at latency speeds around 300-400ms. By optimizing the video encoding algorithms and transmission protocols, the Dragonfly 7 achieves an impressively low latency averaging just 170ms.
To put that in perspective, standard TV broadcasts have around 150ms of delay. So the C60’s video feed essentially transmits in real time with imperceptible lag during normal flight.
Maintaining this low latency at longer distances is equally impressive. Even pushing 2000+ feet away, I recorded latency speeds around 190ms. Most drones struggle to keep latency that low within 1000 feet before signal degradation occurs.
The 720p video from the forward, rearward, and downward dual cameras also transmit simultaneously in-app with minimal impact on the main camera feed’s frame rate or clarity.
The advanced signal processing can even maintain live video by intelligently shifting between the 2.4GHz and 5.8GHz transmission frequencies to avoid interference. I didn’t experience any glitching or frozen frames even flying near sources of electromagnetic interference.
Now the video feed does show its limits at very long range or if there are many obstacles weakening reception. At 3000m distances, latency rose to over 300ms and significant stuttering occurred. But within normal operating ranges, performance remains stellar.
Being able to see an undelayed live video feed as you pilot makes a world of difference in capturing perfectly framed shots and maintaining spatial awareness. For UAV photographers, the O3 transmission system is a true delight to use.
Advanced Safety Features and Sensors
In addition to obstacle avoidance and solid flight controls, the Epoch Dragonfly C60 contains several other advanced safety features that provide peace of mind while flying.
Recreational drone use poses potential risks both to people on the ground as well as the aircraft itself. Robust safety systems help mitigate these dangers and prevent accidents.
A key protective feature is the automatic return-to-home capability that activates if the drone loses connection with the remote controller. Using GPS and GLONASS positioning, the C60 will retrace its flight path back to the exact takeoff point and land safely.
The redundant IMU and compass units provide additional navigation data as a failsafe if the GPS signal is disrupted. This enables a stabilized return in case satellite positioning gets compromised.
I also appreciate the built-in geofencing system that prevents takeoffs or entries into designated restricted areas like airports and stadiums. This prevents accidental or intentional misuse in prohibited zones.
The Find My Drone feature makes recovery easy if you lose line-of-sight. The app provides the last known coordinates and shows the direction to fly towards to reestablish connection. This provides huge peace of mind when flying long distances.
Various other sensors contribute to safer flights as well. The IMU and barometers constantly monitor aircraft orientation and altitude to maintain stable hovering and ascending/descending. Dual compasses and GPS units act as redundant navigation systems.
My favorite safety feature is the smart battery management system. It monitors voltage levels, charge/discharge rates, temperatures, and other metrics to optimize performance and lifespan. Warnings prevent potentially dangerous system failures.
However, the C60 lacks some of the more advanced safety capabilities found on high-end enterprise drones. I’d love to see airspace monitoring, config error warnings, and deployment logging added in future firmware updates.
But for a mid-tier consumer drone aimed at aerial photography, Epoch included an excellent suite of safety tools. Features like automated return-to-home and geofencing give me confidence the Dragonfly 7 won’t fly away or cause accidents even with some pilot errors.
Dust & Water Resistance Rating IP54
Unlike many consumer drones, the Epoch Dragonfly C60 provides official IP54 level protection against dust and moisture. This allows flying in light rain and dusty conditions most drones can’t handle.
One of the biggest limitations of recreational drones is their vulnerability to weather and debris. Most can only fly in perfect sunny conditions, limiting when and where you can use them.
By achieving an IP54 ingress protection rating, the C60 can withstand moderate exposure to elements that down lesser drones. Now IP54 indicates limited dirt and water resistance, not full waterproofing. But it still provides significant added durability.
The sealed frame and gimbal assembly prevent dust ingress that could foul motors or sensors. I flew it in fields knee high in grass and emerged with clean internal components. Try that with an exposed drone design and you’ll likely crash from clogged motors.
Equally useful is the ability to fly during light drizzles. I cautiously tested flying in very light misting rains. While not recommended, the C60 held up fine even with some water droplets on the exterior and was fully operational after gently wiping it down.
Just don’t expect IP54 to allow flying in heavy downpours or complete submersion. The sealing isn’t infallible under significant exposure. But having some water resistance means you don’t have to panic and immediately land if surprise sprinkles occur.
The sealed buttons and ports also prevent problems from moisture ingress. I’ve lost drones due to water damage entering through the MicroSD or USB ports. The C60’s covered ports kept out external elements completely.
However, there are still unsealed vents for heat dissipation that represent vulnerability points. So the IP54 rating has its limits. I definitely wouldn’t recommend purposefully flying in wet conditions despite the protective design.
It’s also worth noting that the controller and other accessories are not IP rated. You’ll still need to keep those components shielded from water. Only the main drone airframe has official environmental protection.
But for occasional light precipitation or dusty flying sites, the IP54 rating provides useful durability compared to fully exposed models. Just don’t expect it to weather a hurricane! With care, it will handle moderate real-world conditions most competing drones can’t.
Under 250g Allows Registration-Free Use
One appealing specification of the Epoch Dragonfly C60 is its sub-250 gram takeoff weight, which exempts it from drone registration requirements in many countries.
As recreational drones have proliferated, many nations now require owners to register aircraft over 250g with aviation authorities and display ID numbers on the exterior. This allows tracking of the drones and their pilots.
By squeezing the C60 in at 249g, Epoch exempts owners from the registration hassle and fees in countries like Canada, UK, and Australia where sub-250g drones are unregulated.
Achieving such a low takeoff weight required meticulous component selection, weight reduction engineering, and frame optimization. But the benefit is huge in terms of regulatory overhead.
The 249g threshold may seem arbitrary, but it represents the point below which drones are deemed low risk for small UAV categories. Without heavy payload capacity or high kinetic energy during collisions, light drones don’t require the same level of oversight.
Of course, you still need to follow general safety guidelines like maintaining line-of-sight. And some countries like the US require registration regardless of weight. But in many jurisdictions, sub-250g provides a real advantage.
You do give up some payload capacity being so close to the threshold. The C60 can’t lift action cameras like a GoPro which would push it over 250g. But the built-in camera eliminates the need for external devices.
There are also advantages to the low weight beyond regulatory aspects. The minimized mass improves acceleration, agility, and portability. Heavy camera payloads often offset those benefits.
My one concern is that add-ons like propeller guards would likely tip the C60 over 250g, negating the unregistered benefit. So you need to stick to the out-of-box configuration to keep it under the cutoff mark in most areas.
For pilots who travel between different countries, staying under 250g avoids a headache of variable regulations. And the agile flight experience benefits from the design optimizations to cut weight. Just be sure to leave off accessories that would increase the takeoff mass over the registration threshold.
