I have had so many failures I'm becoming discouraged :(! I flew through (4) batteries inside the bay, dodging wires and hoses from the ceiling and landing on the trucks without a single problem.

I was just doing a piouette when the quad just began to tumble out of control. I let go of the sticks thinking the boards would be able to re-stabilize, but alas, this was the result:
37683769377037713772

If you listen to the motors, you can hear change pitch just before the tumble. Did I loose a motor? Tx/Rx problems? I won't blame my piloting skills this time...

Ideas?

"lean"-bug? did it tilt to one side instead of auto leveling?

don't give up! you can probably bend all that back, some new arms from the AQ store or home depot, props and you're good.

to me it sounds like all motors stopped at one point before the crash, did you disarm trying to counter the right spin?
was the camera on top? how large/heavy?

q6600: took a while, but I have it back together again. During the flight, I put it in a hover at altitude and just began to rotate. It drifted of station a little bit, so I sped up the rotation rate to bring it back to nose out when it just stopped rotating, rolled and began to tumble. I tried to correct the roll but let go of the right stick when the tumble started hoping the computer would 'figure out' which end was up. I really need to start recording what I see also for trouble shooting reasons. The camera mount is on top and holds the Sony Webbie which actually SURVIVED the impact. I don't think it's much heavier that the GoPro. All my tuning was done with the camera on board because it was up so high.

Thanks for all the replies guys

Update: Fired everything back up a few minutes ago and found that my v2 board is no longer seeing the sensors. Don't know how much damage was done (board failure->crash:crash->board failure) but what I do know is that the voltage regulator is no longer functional. I've had some shorting issues in the past and jumpered around them so the board is to be replaced now. I have the v1 Mini Shield but again, it has problems that I'll post in the Mini Shield forum.

Hope has returned! I do plan on returning to the air soon.

Holy Moly! I'm blown away by the destruction. If I was to give out points for the worst damage, you'd be at the top of my list.

But in all honesty, it sounds like you really are at the tail-end of the steep learning curve. It takes a few batteries, a few wrecks, a few fixes, but then you really can fly for a while without breaking anything. I have been learning flips and figure eights over the last month or so, and haven't even so much as broken a prop in weeks. Feels nice.

Stick with it, it gets better: http://www.youtube.com/watch?v=7skPnJOZYdA (Watch that. Be nice to gay people. For real. Then, watch it again, replacing the word gay with quad. You'll feel better too.)

I am still learning, doing the figure 8 and all that, got the hover thing down in nose out and that is all I was trying to do, just at altitude. This particular quad is v4 or v5 ;) I think the only thing from v1 is the battery mount and landing gear.

I keep telling myself that this is only a 'hobby' but my wife thinks it's becoming an obsession ;)

Ok guys, thanks for all the help! Even more thanks to aadamson who helped me sort out the MiniShield problem. For everyone else, this is what it's supposed to look like! It does fly different from the Mega/v2 shield, had to retune a bit but it is flyable. Noticed that the motors don't respond as fast to throttle input, but the pitch/roll seems a bit twitchier. I'll fly these settings for a while since they work (yea), then start messing with it again.

Cheers!

John
