BIG BUBBLE is fully aerobatic model powered by electric motor. 

The model is supposed to be flown by advanced flyers. It can be "hanged" vertically in the air (torque roll). The knife edge flight is surprisingly easy.

The model is excellent for 3D outdoor flying.

The fuselage is designed so that you could use various types of motors and batteries.
