RE: good beginner gas plane
Well, there is one combination that is a proven winner time and time again for a beginner would have to be a Sig LT40 ARF with a OS 46FX. More on the higher $$ end, but worth every penny. And with any luck, when your done with the LT40, yank the motor and slap it on your next plane like a stick or a 4*.
