That video is amazing. After 6 months and hundreds of hours on the sim I can now hover in place tail in with a 450 heli and putt around a bit. Learning how to fly helis take a lot of dedication and research.
I definetly would like to see some Castle offerings in the outrunner department. Right now a castle motor for a 450 size heli would be nice and a couple of outrunners in the 35 x 30mm range for some nice 3d flying.
