Question; I am building NitroPlanes CMP P-40 War-Hawk 140 73" span, Basic kit 10.75 lbs. Recommended Engine(s) 2stroke. 1.08-1.20, 4stroke. 140. I have not bought the engine yet but its going to be gas. The pre-built plywood engine mount is part of the model's structure and designed for the standard glo fuel engine installation (no Standoff). I want to build this bird with retracts and flaps so it will be closer to 14 lbs. RTF. The CPRC-pro 26cc and the Evolution 26GS or maybe the Evolution 40GX[X(] are some of the engines I'm considering because they have glo style mounts. It makes me wonder, Is the extra vibration of the gas engines the reason most have standoff's?. Would it be better to modify the structure of the plane and use standoff's? Would the Evo. 40 be too much?[
