My P3P was delivered yesterday. Spent some time getting it all set up. Over the last couple weeks I spent a lot of time reading and watching vids to familiarize myself with the quad. Got it up without a hitch. I was trying to go slow and take it easy. Felt my 1 acre back yard was enough wide open space but the trees and power lines suddenly made it feel very small. I had it up for a good 10 minutes and as I was trying to bring it back to land, I panicked as I neared some trees, it went into some branches and came down. Luckily a smaller tree lent a hand and broke its fall. The battery popped out and it sustained a small "dent" in the shell. But I went though the recalibration process and I was back up and running just fine in 15 minutes. Definitely shook me up, watching a $2000 investment tumble to the ground. Lots to learn.
