That was great vid!!
So that was with the stock motor on 4S? Great, I may give that motor a second chance on a new project. I added hinges to mine and a V2 SuperSonic on 3S. The first time out half throttle and it took of verticaly from my hand. I was not ready for that and with my throws set high it did a backflip
. But all is good. I need to find a larger field to fly at like yours, that looks great. My closest field has a perimeter of trees
. Not a good spot for my little rocket.
