I have done what you want to do. I started with a Hangar 9 Arrow/w OS .46 AX engine. Flew on buddy cord with instructor for 4 flights and then solo'd. I can say that glow power for me is much more fun than electric. Things happen quicker with a 40 sized plane than a Formosa. However, you should have the basic feel for flying because of your experience in electric models.
