New, larger version of the Challenger from OMP Hobby. 59 inch wingspan, super light balsa and play construction with a high visibility scheme that has been very well applied in the factory. I used the recommended SunnySky brushless motor and ESC with Eolo propellor. Takes 4 standard servos. Can use 4S or 6S packs. I used a 6S4000 and barely used full throttle.
