These two new E-flite UMX planes are sold separately but you will find that you need to have them both. Our writer Michael York found that the Cub had ample power to quickly get both planes airborne and skyward. He states, “After a very scale-like liftoff, we climbed in a large circular pattern up to altitude. It was obvious that the AS3X system did a great job maintaining stability under tow, even when things got a little out of whack while testing out various tow positions. After releasing the towline, the ASK smoothly glided back down with a short rollout landing.” See what else he has to say about these great planes in the video below.
