Yes I have and I'm well aware of how dangerous they can be, as well as quads. I'm just surprised that the tech for helicopters hasn't evolved as well as it has for quads.
My first was a big Kyosho Kit I must have bought 2 kits by the time I got it all pieced together (this was before the internet!) Once together I got it off the ground after sweating it out, and as it drifted towards me I freaked and I slammed it...
I have been flying RC my whole life..I flew or tried to fly helis a few times its just too darn scary for me I messed up and started with a big one (MISTAKE!) after the crash and thank goodness non injury I got a little blade chopper they are...
