Well, you are not alone in being abandoned by a copter, Teach. My Nano QX is hiding in the backyard somewhere! Took it outside yesterday to try some flips. Bad idea as the wind was blowing harder than I thought. I had it up sort of fine at first and then a gust took it out into the pasture. I kept catching it but wasn't making any progress back due to the gusts. They just kept knocking it off track and I finally just dumped it thinking it would be better than it flying away. If I could just find it! It's out there somewhere, mocking me!Just to jump in here...
My bat bone easily reached 10 minutes on a 2200 mah, 3s with 1300 kv motors.
Then it flew away...
But, I have a much better tricopter, now. Gotta love a larger airframe with DT750's!
