I got an Hanger 9 Xtra Easy with a field box radio and everything needed for a day at the field. I got all this for 80 bux!

the engine is a MDS 40
It came with a JR 421 computer radio.
I got 3 flights out of this plane. Killed it on the forth. (newb trying to fly in to much wind)
I have been flying on Real Flight G2 for about a year.
My question is: should I just by a tower hobbies MK II trainer for 60 bux and install my gear in it or would something else be more suitable?
My flying area is pretty rough terrain. ( the accasional tracter rutt)
