Like its predecessor, the mCP X BL gives you the precision and stability of the proven AS3X® Flybarless System. What sets it apart is an all-new rotor head with longer rotor blades, as well as a brushless power system that blasts mCP X performance to thrilling new heights. Inverted flight, flips, rolls, funnels and hurricanes only scratch the surface of the capabilities the mCP X BL has to offer. Push this heli hard with left and right pirouetting maneuvers and you’ll be rewarded with crisp, precise tail response unfettered by a lack of power. The only limits are your skill set and the space you have to fly in!. Key Features: AS3X® Flybarless System. Powerful, 6700Kv brushless main motor. 8100Kv brushless tail motor.
