I have a YS 120 in mine. Flies fine. One thing to look out for is the covering, I have the purple and Silver version, both purple and silver does not stick very well, tape down all the leading edges of the trim. I don't like the fact that I cannot remove the batteries easily after a days flying, I don't like to leave them in the plane, there should be a hatch on the bottom somewhere, because taking the wings off is a pain! Landing gears are super strong and super heavy, it's difficult to land smoothly on paved runway without bunny hops! No real issue with the plane.
