Ive looked at everything on this plane and been impressed with the quality of everything except the plastic engine mount. I wanted to use the DuBro rubber isolation mount but it put the engine another half inch forward because of its thick isolators, and extra clearance need forward because of the four stroke carburator, hence a balancing issue. Im not to the point of balancing but does the plane tend to balance tail or nose heavy? I guess my question is has anyone had any issues with the stock engine mount? It just looks cheap.
