Obstacle avoidance – The end of crashes?

Posted on Leave a comment
DJI Mavic Pro

Are crashes a thing of the past? While obstacle avoidance should reduce the likely-hood of piling your aircraft into the ground, there are many scenarios where these safety measures will fall short. When in doubt, consult the manual included with your aircraft or at least watch some crashes on YouTube for your model. While this post doesn’t address every possible scenario, I do hope to outline the majority of reasons you should be on the alert even when flying an aircraft with avoidance.

Small obstacles

Tree branches and twigs are a nightmare for avoidance systems. Their round shape and small cross section are practically invisible to sonar. Forward facing avoidance cameras are unlikely to lock on, especially if they enter the field of view suddenly or from slightly off center.

When it’s off ( No kidding )

Sounds crazy but yes, people often will disable the avoidance because they’re intentionally trying to fly through or near something on purpose. A good example of this would be when you’re trying to get a close look at the roof of your house or want to fly past an object of interest to jazz up your next video clip. Often avoidance will ruin these shots, causing your aircraft to stop suddenly when you don’t want it to. Pilots in these scenarios will disable avoidance and forget it’s off.


Avoidance systems rely on an array of sensors with different capabilities. Low light or low contrast surfaces have posed issues in the past and will continue to in the future. Avoid surfaces that are glossy, all one color or places poorly lit.

High Speeds

Depending on your model, flights at high speed can render avoidance useless.

Over Water

Water is especially good at confusing downward facing cameras and sonar, especially if there are waves.

Backlit shots

All cameras must have good exposure to work well. While sunsets are glorious, the glare can defeat even the most robust systems currently available.

Pilot Error

The biggest problem with avoidance systems is that pilots get a false sense of security. Assuming a crash is impossible causes many pilots to fly without fear. Even worse, some pilots will make it game to fly towards objects or people to demonstrate the avoidance capabilities. Always consider these avoidance systems to be emergency backups to safe piloting practices.

Posted on Leave a comment

Joystick for Freefly Movi Pro available soon.

Full proportional pitch and pan control.

Direct plugin to COM 2 of the Movi Pro Controller. The advanced controller built-in the joystick allows you to access all the features with click combinations. Example, on the fly dual rate (dual speed) function will let you pan left at full speed and then, double click, pan right and half the speed in one smooth motion. The built-in non volatile memory will store all features even when the Movi Pro is switched off, making it a snap to switch packs and go. Axis inversion is also built-in and can be activated for pitch by clicking 4 times and for pan by clicking 5 times.

DJI Releases DJI Mavic Pro – Palm Size Folding 4K Drone

DJI Mavic Pro

The DJI Mavic Pro is a small yet powerful drone that turns the sky into your creative canvas easily andwithout worry, helping you make every moment an aerial moment. Its compact size hides a high degree of complexity thatmakes it one of DJI’s most sophisticated flying cameras ever. 24 high-performance computing cores, an all-new transmissionsystem with a 4.3mi (7km) range, 5 vision sensors, and a 4K camera stabilized by a 3-axis mechanical gimbal,are at your command with just a push of your thumb or a tap of your finger.


Inside the Mavic’s pocket-sized remote controller is DJI’s brand new OcuSync transmission technology, with a range of 4.3mi (7km) and Full HD 1080p video streaming.

Satellite positioning can only help a drone hover in an unobstructed outdoor area free of interference. Without satellites, the drone will not be able to position and become susceptible to drifting. However, with forward and downward vision sensors, the Mavic can hover precisely indoors or in places without GPS.


The Mavic is only 1/6th the size of the Phantom 4 but this reduction in size doesn’t mean a reduction in flight time. The Mavic actually flies much longer than you would expect from its compact size. It is capable of reaching an absolute max flight time of 27 minutes and a maximum distance of 8mi (13km) due to its powerful, high efficiency motors.


Mavic supports 4K video at 30fps. No Electronic Image Stabilization is used, ensuring all footage is 4K. We have created a miniaturized, ultra-precise 3-axis gimbal for the Mavic, capable of stabilizing the camera even during high speed motion for smooth video and sharp photos.


Everyone loves a good photo. Whether you just want to take a snap or are building up your portfolio, the Mavic’s 12-megapixel camera with Adobe DNG RAW support is ready to shoot.
