I have done/did the same as you. Electrics for 3 years and getting into glow. I still fly my electrics (gotta love a 120 mph sailplane!!)
because I have a private farm. This is what I did. Bought a Hangar 9 Arrow. Its a trainer/aerobatic all in one. I put in a OS .46 AX engine. Joined AMA and local club. Flew with instructor via buddy cord for 4 flights and then solo'd. I still fly it and do immelmans, inverted etc. all your general aerobatics. Going to maiden a Twist at the field tonite. So, if you can fly electric, then your transistion to
glow should be relatively easy. Its just glow is bigger and fly a little faster.
