Hmm after all that has been said im pretty sure i want to go with a 50,
I actually tend to pick things up quite quickly, first time i flew a 450 it was hovering just fine within the first flight, plus im not brand new to flying, just new to helis. I can already do almost full out 3d with planes in the 100cc size range. But i know heli's are much different and im looking forward to a challenge
As for choice of heli's i still cant decide which 50 size to go with, i want something that will be as cheap as possible to repair after a crash, so if a t-rex offers better crash resistance it may be better to go with that.
Thanks,
Darren
