I thought it would be too heavy too. The one in the video has the rimfire on it, and a 3cell 640mah lipo. It weighs 14oz, and has plenty of power. I run a 9x4.7 APC prop on mine. Works great. It will hover and climb from a hover. Always had plenty of power for any 3D stuff I wanted to do. In that video, I never got it above 3/4 throttle.
Its the CR-2, just without the SFG's on it.
