Is it possible to replace the wing on an exsisting trainer after you learn to fly to a flat wing that is more aerodynamic.

Sure. This is commonly known as "Kit Bashing".

yep, but generally after all the trouble the plane which used to be a good trainer ,isn't good for anything any more.
Have a goodun,John.

My advice keep it as is. Its great to have a trainer to fall back on. I allways try to have one airworthy all season.
Here's one mod you can make add a drop box great fun.
I'm adding one to mine going to try dropping those snap cap things!!!!

How about a tiger2 or a sig 4*??? great planes that way you'll have to incase something happens to one you can still fly and fix the other at your leisure.
