A friend of mine has a CA Model Genesis with a ZDZ 40 Re F3A Gasoline engine with a ES Composites carbon fiber pipe. Very good combo with good power but not as much as YS 170 or Hacker powered models. My biggest concern is airframe durability because engine vibrations. This models are built glass-foam-glass sandwich, I think it could be a better choice for the DLE 30 gas engine a wood airframe like the Epsilon 120.

Just my opinion.
