Landing a Quad on a moving car via FPV

Posted on December 22, 2013 at 8:30pm 12 Comments

I tried to do something different this time: land a quad on a moving car.

After 2 unsuccessful attempts (crashes), the quadcopter finally did a smooth landing on the roof of the moving car.


The RC quad was controlled from the inside of the car using a 7" monitor (480x234 pixels) for FPV. Video was transmitted directly from the onboard GoPro2. A…


Dual redundant BEC + overvoltage protection (crowbar circuit) to power the flight controller?

 or   ?

Hi, when i fly multirotors one of my main worries is to avoid it from crashing. Mechanically I've practically solved it because I usually fly an octocopter (motor, prop and ESC redundancy). My main concern right now is how to power the flight…


Octo X8 Coaxial - testing motor redundancy

Posted on August 7, 2013 at 3:30am 16 Comments

Testing the octo without 1 of the top motors and then 1 of them bottom motors to check what's happens if a prop/motor/esc gets bad during flight.

Previously I've done the same test with a flat hexacopter and an Y6 but they didn't performed very well.

With a flat octocopter, if it looses 1 motor/esc/prop it's barely affected. I was…


Mechanical gyroscope gimbal: 2nd test (pitch / roll)

Posted on June 26, 2013 at 3:00pm 8 Comments

2nd test with the gimbal: 2 axis, pitch and roll stabilized by a homemade mechanical gyroscope. Using a GoPro

In this second test, I added another joint so it can move freely in 2 axis as seen in the beginning of the vídeo. The performance was nice although i performed some very aggressive movements.

PS: i didn't use any bearing in joints,…
