RE: 15cc Gas RCGF engine information thread
The 15cc weighs 33 oz + batteries and switches.
It is a heavy engine in comparison to .40 - .60ci engines that range from 12 to 23 ounces ready to fly.
The output of the 15cc in comparison to glow engines is much less too. There is also the penalty of wing loading being much heavier. It will affect the flying characteristics of any aircraft it is installed into.
Making a light 15cc gas engine is pretty difficult to do. That is why most manufacturers stick to making gas engines of 20cc+ for aero applications.
