Hi Graham,

Do quads have control schemes that make sure all four ESCs would give a low-power cutoff signal at the same time or are otherwise programmed the same?  It sounds as though one ESC has a low-power cutoff coming sooner than the others.  I would think that quads would somehow assure this doesn't happen, though, so maybe this can't be the cause of your problem.

Thanks,
Paul

Hi Paul, the "problem" has it's own thread here although I've been sending Jason logs and have been having some discussion with him via email. In short all the ESC's are identical and are programmed the same. My RC Tx has telemetry and I ensure the flying voltage does not go below 10.4V. The ESC does not cut-off per se but the signal seems to 'top-out' rather and the motor loses power which causes the opposite one to compensate. I can put a couple more logs up on that thread if you want to have a look?

On mine motors stop randomly, It can happen after 15s, 1 min, 3 on any motors with no apparent reason for 1/4s enough to crash. Anyone ever tryed tower pro 25a (not i2c) on quadcopter ?

Cool fpv tough.

Hi Graham Thanks for sharing through FPV I get to see what it is like in Other parts of the world . I notice the sun is setting or coming up the Elephant is casting a large shadow  For us that live in the 'tame "world it might be kind of "creepy"  there after dark? Then again it is probably safer than your average city. I am glad you got your equipment back . Have a Nice Day!

Thank god the elephant didn't see your quad as an enemy! I found out that my old gaui 330 is no threat to dogs and even ducks! On one low flight over high grass a roaming dog suddenly jumped up and tried to catch it. Even ducks seem to be interested and come closer. I will check out cows next. But this has been done before: http://www.youtube.com/watch?v=mQfOtFSNZ18&feature=plcp LOL

Thanks Carl, it can be kind of creepy after dark but we always carry good torches (flashlights), are alert and don't venture at all far from the tent (which is actually safe). I'm generally comfortable seeing a lion in the day on foot but am overly cautious with them at night, they change personality a bit... (and we did have them in our campsite on two occasions!). I'll be posting another video or two of that area from the quad soon.

@Crashpilot1000, I'm very nervous with dogs at our flying site, as people walk them in the area. An 11 inch blade at 7000rpm will do a lot of damage. I had a young german shepard dog want to bite the quad once, so I asked the owner to hold him and then landed, once the props had stopped I said he could let go, the dog ran up to the quad and I gave the throttle the tiniest of blips just to give the props a turn, one the props tapped the dog on his nose and that cured him of wanting to bite it forever! He wouldn't go near it again.

I did once hear of a small dog being killed by a 450 size chopper at a park, the dog ran right into the spinning blades just after touchdown.
