This Ultimate is not a beginners airplane. Stay with 2.4, tried and true and easy to obtain. Stay away from other peoples junk, usually unreliable unless you really check it out.
The cub should work well as a trainer altho not as well as some real trainers designed for that purpose.
Often first timers tend to get a little ahead of themselves and obtain "stuff" that it turns out they don't need. I did! (still do).
Keep it simple and have fun.
