I have had an itching to play with the RC helis lately. I have been flying a CX3 for a little while and feel that I am getting rather good with what it can do. My house space is limited and would like to get a heli for the great outdoors.

I have heard some of the views regarding the electrics Vs. Nitro and most seem to be focus on clean with the down side of cost for the batteries. The Nitro is cost savings for the initial price. They both seem to be close in the noise factor with the nitro a bit louder. I am looking at a Trex 600 ESP or the Thunder Tiger Raptor .50 right now. I also think I would like the scale side of heli flying with some aerobatics and not extreme 3D. Should I start with a smaller heli (450)?

Can anyone give me a view and data (if available) to helpful in choosing a heli?

Thanks!
