Powerful enough to flypaper, balsa, cardboard, foam and even lettuce planes, the POWERUP 4.0, meshes technology with the thrill of sending homemade planes into the flight to bring out the kid in all of us. The POWERUP 4.0 is the best POWERUP yet with an onboard flight computer, autopilot assist, gyro and accelerometer with fly by wire capability, and flight telemetry stats. The POWERUP 4.0’s two propellers provide double the power and more maneuverability.
