Sounds like the hot ticket for a new balsa tree. I wouldn't want to risk an expensive motor like that on a first time plane. I dont have a Ucando but the magic extra is somewhat similar, The plane can be slowed down to a crawl at landing.
I'm just getting back after a number of years, i prefer the ME to my rascal, landing is much easier. the rascal glides forever, you need a long approch, in the past 2 "instructors" have put it in the bushes for me. The ME slows quickly and lands on a dime.

In short its probably not a good idea. There is some truth in saying that 3d aircraft can be easy to fly with minimal throws and proper throttle, but unless your friend is wealthy he should try to heed conventional wisdom. At least get a semi symetrical hi wing type (trainer) with an affordable 2 stroke.
