It not a stupid question if you dont know

The Raptor 30 can indeed do basic (and some advanced) 3D, Ive got a Raptor 30 with a os37, standard head, and carbon blades. And it can do inverted, loops, rolls, and tick tocks (with carefull collective stick managment ,all be it a bit slower than a 50).

And to be honest theres not a lot of diffrence in price between the 30 and 50, Apart from a small diffrence in fuel consumption.
To be unbias as I have a 50 aswell, If you havent bought it yet, then go for the 50 [8D]
There is a video somewhere with Alan Zabo(sp) doing what he does with a 30.
