my second test fly of the day ended very bad..... airplane crash

my first try; the (one in the pic), was made with all the servos conected on the receiver, so i was flying using ardupilot only for telemetry....
everything was good, landed and posted the photo...

second test was done with ailerons and elevator conected thru the ardupilot.........
took off, a few turns, trimmed the UAV, and gave a try to the first mode, STABILIZE, the airplane wanted to go down and to the left in a very soft fashion,,,,,, made a second try and it was the same result..... kept flying in manual mode for some minutes and then it happened...... the airplane started to make strange things, in that moment, while i was trying not to brake the thing, i confirmed the throttle working perfect, so my first opinion was that the AP was rebooting, the only problem was that the UAV lost altitude and chashed....

Thats a bummer. But thats the nature of this hobby. Try, fail, adjust and try again.

i wanted to test this today:

with the crash i broke the micro servo on the back of the camera......... can you imagine the camera full of mud...???

Diego, nice work! Any interest in doing some testing for me?

hello Happy, i will start the repairs, next sunday i will fly again, i have to make this work, this week i will get my ardustation, i will use it to track my uav with a patch antenna that i have, and also gonna get my remzibi´s OSD!!!!
You can be sure i will test your software, i have a lot of work to do, beside repairing the UAV i will be working on the AP manual translation to spanish....

You've got a lot of work to do! Good luck!

I hope you've seen the threads on RCGroups about the ArduPilot interfacing with the Remzibi OSD :)

Diego, sorry to hear about the crash, but now you're in the REAL UAV club! If you haven't crashed a UAV, you're not really flying ;-) (I've crashed dozens)

Even if the autopilot were to reboot in flight, you still should have been able to regain manual control. That's why the failsafe/MUX is on a different circuit. The only way you can fail to regain manual control is if your entire board loses power, but since it should be powered by the RC Rx, that means that your RC died, too. In that case you have bigger problems than an autopilot...

If I had a dollar for every crash...

I found that I used to be overly shy about going back into manual to save the plane. I would let the plane get into situations that were too difficult for such a lousy pilot like myself to get out of. Be more cautious and fly a little higher. If something isn't working, don't fuss to much in the air, just bring it back down and do more testing.

As Chris said, I'm a little confused why the plane was behaving strangely while in Manual mode. This indicates something wrong with a servo, linkage, or your ESC cut out because of low voltage. Are you an experienced flyer? Let me know how I can help you through this.

Jason
