This is a true T-rex 700 in size with a Scorpion motor running on 12s lipo pack , it runs a very high headspeed and is very responsive. If you like to fly 3D then this is the big heli for you , as far as I can find it has no bad habbits and will do anything you can throw at it . Hope you all enjoy and please feel free to rate it and leave comments. NOTE THIS IS NOT FOR BEGINNERS
