if you can fly and land the trainer, I say do it. i went from a high wing trainer to a stik and the stik actually flies better than any trainer ever could. Keep the rates turned down to a minimum on the ailerons, rudder, and elevator and just remember there's little dihedral in the wing for self correcting tendencies. Buddy box it for the first several flights until you're comfortable. I think you'll find that after a few flights, you'll agree the stik is 100% better than any trainer. If I could do it over again, i'd have started with a stik instead of a trainer. Then I wouldn't have outgrown my first model so quickly. The stik is a dream to fly in the wind and basically slows to a crawl for landings. I think you'll very much like it.

As a plug, I'd recommend a Big Stik 60 with an OS 75 or 95. You won't believe how slow you can get it to fly and then rocket out like the space shuttle on full throttle.
