RE: Engine shock mounts
all of my gas engines have rubber mounts even have the G26 with them . saves a lot of vibration thru the F/wall & airframe & also the radio . Basically I put a piece of 3/16 alum plate
on the back of eng rear of the muffler , bolted to the eng; the plate is aprox 4" sq on the G26 & has 4 rubber s a pair on each corner -total 8 rubbers , a 1/4 " or 6 mm bolt goes thru the rubbers into blind nuts in the f/wall . lock wire is connected thru the bolts to make sure they don't loosen .
