I'm on my second Shockie. The first had an Axi 2208/34 and was really good, but the new one has a cd rom brushless and is lighter. I have the Hell Raiser also. I have flown a friends Tensor. Of the three I recommend the Shockie for the backyard. The Hell Raiser needs more room. The Tensor doesn't "feel" right to me (may be a builder problem though). I fly in an area of my backyard about 80' X 100' with no problem w/ the Shockie. 5mph and less breeze.
