Ok, Time to beat the drum again. I'm done with all my trim monokote (Thank God), have completed the servo mounting in the wing for the ailerons, and am now ready to mount the engine. As suggested above, I went to install the engine (Its been on another plane until now) and the ply mounting is about 1/4" below what I need for clearance for the muffler, needle valve, and idle\throttle adjust. My options are A: Cut the engine side cowls for all 3 mentioned, or B/my thought: Raise the engine mount 1/4" to give the needed clearance for all 3 mentioned. Question is, by raising this for clearance, am I asking for trouble in performance or handling, or is this in a ballpark that’s doable? Some shots............ Thanks in advance, Greg
