Throttle linkage is done. went under the exhaust cut out and thru the angled back wall. Fuel tank and lines are installed. Since I moved the tank back toward CG I'm hoping the extra length in fuel line won't affect engine performance. It's an OS FS 91 w/ pump. I think it should be ok. For some reason when I install the stock spinner the plastic back plate warps when I tighten the Propeller nut. Making it difficult to screw on the cone. Finally all thats left is to mount the RX and battery - connect all the servo wires - and balance.
