getting ready to hang power on my exp.-18,question is,there is 1 1/2 lbs differance between a 135 h.p. mount and 150 h/p. mount. i have both and talking with lee when he owned airframes, he told me when they connducted certification tests the only structure that didn't fail was the engine mount!!
so was wondring if any one has run the 135 h.p. mount on higher h.p. engines??? the differance is wall thickness,would like to lose the weight,but don't want to lose the engine!!!!
