About this 3D model
This is a frame based on the deadcat quad copter frame. It is completely compatible with the sk450, however it is not compatible with dead cat frame. Enjoy Should also mention that the slots at the front of the frame have been widened to fit this gopro camera gimble: http://www.hobbyking.com/hobbyking/store/__27153__Multi_Rotor_Roll_Tilt_GoPro_Hero_2_Camera_Mount.html
