RE: Equivalent Gas Engine Size to Glow Engines
Looking at the math 10CC equals .60 2 stroke glow.
As said above anything over 1.20 glow I'd use a gasser. Fuel is cheaper and the flight time per gallon longer. As far as power goes a 16 lb Yak 54 with a 55CC gasser.will go straight verticle until I pull the throttle back.
Good Flyin to all
