I was quite surprised to see a quadcopter flying that high! It was done by Денис Корякин as shown on his youtube channel.

We are now shipping the RCbenchmark Series 1520. It measures overall efficiency, current, thrust, voltage, and motor speed. The device communicates with our…Continue
How do you estimate motor torque and efficiency from basic measurements? It is useful to know this information to improve flight time and performance. The video explains the fundamental relationship between Kt and Kv. It turns out you can get a lot of information from the motor Kv.
This video is part of a series. There are more tutorials on the…Continue
As promised, here is part 1 of our series on motor and propeller theory. Part 1 covers the coil magnet model, Kirchhoff's law for a motor, Back EMF, Kv, Kt, and motor efficiency.
By the end of the first video, you should really understand why is a motor is inefficient and the relation between electrical power, heat and mechanical power. The motor model is…Continue
I was invited by OttawaDrones, a group of FPV flyers and drone designers, to do a short presentation about our dynamometer. My objective was to help them make quads and drones that fly longer and are more powerful.
I decided to do an…
The challenge for the next five years for drones is environment awareness. Drones have been doing quite well in the lab because they have precise positioning systems. Outside, drones have to rely on SLAM, which traditionally uses heavy, expensive laser depth sensors. This is why any development of low cost depth sensors will have a big impact on the future of drones.

Please comment and send feedback below. A few months ago, I posted here asking if you would be interested in a dynamometer. I received quite a lot of comments. My colleague and I had the idea of a dynamometer for brushless motor after working over one month…Continue
Transport Canada will investigate the use of a Quadcopter for shooting fireworks. It is again people giving unmanned vehicles a bad reputation. Shooting fireworks on someone is plain stupid, I think we can agree. However, should Transport Canada be handling this case? What if they were shooting from a radio-contolled boat or car? The danger is from…Continue
Drones may take advantage in more than one way of the virtual reality buzz. Valve announced its Lighthouse positional tracking solution along with the HTC Vive, and more details are emerging about the inner working of the system. You can see above the…Continue
