"why over thinking it? keep it simple,less thing to go worng.if you must a trap with two nets that fold upward to capture the quad.you land on the trigger and bam it closes.  "

"Yeah Regarding the net idea, the reason I though a net is, it both give much more catch loops, and also if its high enuf off the roof (compared to the feet) it may avoid some paint scratching contact, or cushion a rough impact. But yeah...fun…"

"That´s nice too Morli! Could even try it with a plane hhehehe I had to put the antenna upright because if it was on the most horizontal position, it would be closer to the quad, at the level of the props, so no good"

"Agreed ,  Quad and Car antennas don't  go along :). No need for net and hook , just  tie nylon or fishing lines across two roof rails one feet spaced. say 4 or 5 of those should cover the roof length. When Quad drops, the leg/s…"

"Looked like it crashed onto the car as it hit the antenna, as opposed to a "soft" landing. But it did make it safely!"

"What about a system like air craft carriers. Put like a semi tight cargo net across the roof racks of the car. Then have a hook on each foot of the copter instead of the foam. You can then pretty much just get above the car and drop the throttle.…"

"Very cool but it seems like there should be a way to do an auto landing on the car by using a follow me box and arducopter. Wonder if anyone's tried that."

Landing a Quad on a moving car via FPV

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 GoPro3 was mounted on the top of the car. The quadcopter used a simple Multiwii controller board with acc + gyro. The PIDs weren´t tuned so the flight…See More

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,…
