Hey guys lots of reading holy cow! I am just getting into gas engines and have gotten a 74" extra 300 they call for a 120 to 150 4 stroke. I was considering putting in a gas engine but not sure if this is even an option for me . There are a couple of engines that interest me the ZDZ40 or the First place 2.4 .. But this plane says tht it is to be 10 lbs or so. Is that to much engine for the planes airframe...

THanks alot..
