Hello... I would like your opinions on this ...
I'm building a TF Sea Fury, from the posts herre on RCU this plane needs quite a bit of nose weight, like a pound. I was thinking of putting the Evolution 26cc gas engine instead of an OS or Saito 120. The gas engine weighs a bit more than the glow and lots more power. My concern is if this is too much for the airframe to handle. And I would like to get my hands on a gas engine for the first time, am I correct for sayin that gas engines are alot cleaner than glow? The dimensions of the 2 engines are about the same. Let me know what you guys think. btw, is there a smaller sized gas engine available?
