They Suck!!!
OOps...did I say that outloud??? They dont really suck, they are just no comparison to a nitro collective pitch heli. I bought one because I wanted my wife to learn to fly and I sold it right away. Some people like them. My guess is you will want to sell it and get a heli with collective pitch very soon. But it could also be a cheap way to see if you are interested in heli's.
Do some searching on this forum, there is a ton of info on here. Look for a used setup for sale.
I wasnt much help was I?
