OMP Hobby 49” Challenger is a sport RC model airplane built in the traditional way: balsa and film cover.
The airplane features light yet strong structure, low wing load, and abundant power, making the airplane
easy to fly and capable of a lot of advanced aerobatics, such as all P3A and a few 3D maneuvers. This
airplane performs very well in either low or high speed, with great authenticity and precision in response to
radio stick movements, ideal for pilots who graduated from trainer airplanes to the next level of skills.
The optional 49” Challenger receiver ready version is an almost completed kit in factory. Motor, ESC,
servos, Ailerons, elevator, are all installed. Landing gear is preassembled. Propeller is included in the kit. It
takes no more than an hour to put the kit together and ready for the sky.
