Excellent slow-speed capability and stability, more flexibility in controlling with larger ruddder, and perfect aerobatics performance with powerful motor. Beacause of its unique light weight structure and power, this model is capable of repeated take offs and landings from short grass and capable of performing very entertaining aerobatics such as inside loops, outside loops, axial rolls, inverted flight, knife edge, stall turns, hammerheads, spins, and others we have never seen.
