Converted my yelow nitro SSH to FE power. Have to get a new cowl made, nitro one had air vents cut in it. Stock UL1 motor and esc 4600 nimh batteries. Will get some lipo power for the spring running. Nimh batteries fit ok in front of the motor, esc and rec on top, used a rubber band over the top to hold everything down. I used a traxxas waterproof servo for the rudder. I just ca glued some 1/8th ply in the engine well sides to screw the servo down.
