Wow! This info is great! I am AMA and have been with the nitro and gas airplanes for a while. This is one reason why I was looking at the nitro helis. Kind of use to it. I can definitely see the advantages of the electrics in the stated scale application. I have seen several videos and agree that the electrics do have a turbine sound to them.

Are the nitro helis higher performance?

What about a starting point? Is the Trex 600 ESP electric too much to start with for a low time, sort of heli pilot (just flying the CX3)?
