The E-flite UMX J-3 Cub BL is an ultra micro-size tribute to the Lock Haven Yellow airplane. An upgrade for veteran pilots, the E-flite J-3 features a 2S brushless outrunner power system that allows you to cruise the park, or push the throttle to the limit and perform basic aerobatics like rolls and loops. Lightly constructed, this timeless classic features an authentic outline with molded surface detail. But the feature that will help you enjoy flying this Cub even more is AS3X technology. That's because the AS3X system built into the ultra-micro 6-channel receiver has been finely tuned so you feel as if you're at the controls of giant scale J-3 that's been expertly trimmed right out of the box. Molded hard points in the belly make the installation of an optional float set simple. So whether your fancy is doing touch-n-goes all day, or just cruising around, this fully assembled charm-machine gives you everything that's great about the J-3 Cub and more.


AS3X® Technology 
The advanced AS3X® (Artificial Stabilization – 3-aXis) system built into the Spektrum™ 6-channel ultra micro receiver is what helps give the E-flite® UMX™ J-3 Cub an incredibly smooth feel in the air. It's technology that combines 3-axis sensing with exclusively tuned flight control software to help counter the effects of wind and turbulence behind the scenes. As a result, your workload to fly smoothly is significantly reduced so you can enjoy natural feeling control that's precise. It's an impressive flight experience that will have you feeling like you're at the controls of an expertly-tuned scale model that's much larger. 

Brushless Power 
The 180BL brushless outrunner motor installed spins a two-blade propeller to provide outstanding thrust and throttle response for slow flight and basic aerobatics. 

Scale Detail 
Authentic factory applied graphics complement the Lock Haven Yellow painted finish while the wing struts and exposed engine deliver an unmistakable sense of realism. 

Optional floats 
Turn your local pond into the neighborhood RC sea port. Just add the E-flite float set which mounts to the hard-points already built into the fuselage.
