Model plan engines for radia controlled plans?

what is the engine size you are allowed for starting model flyingModel plan engines for radia controlled plans?
I've never heard of a size you are allowed to have. But the engine size is usually fitting to the size of plane you start out with. You'll want to start with a fairly large high winged trainer. Mine was a .40 cubic inch engine. It had enough power to do some tricks, but it wasn't over powering.Model plan engines for radia controlled plans?
You are alowed any engine as long as you can fly the aeroplane. Join a club first to learn to fly models. Doing it without experience is costly and also extreamley dangerous. Model flying isent as easy as it looks. your instructor will probarbley start you off with an electric glider or a trainer with a 40 engine in it. Good luck
