I plan on mounting the 25GT to the engine box and route the fuel lines out the side of the engine box. Remember these gas engines have a carb that has a pump on them so the location of the fuel tank is not as critical as with glow. The fuel tank will be moved about 2" toward the rear and supported with form rubber. These gas engines are just about 1" longer than the 160 glow engines that most pepole use on this plane and even with ei the gas engine will be a little heavier than the glow so mounting the engine like this will help keep the CG. This will also help with insatlling the cowl.

Thanks
