Our air club is about starting to restore a long time grounded PA-18-135 and I wouyld like to ask what are the mods needed to power our plane with an O-360 engine since we are planning to use it for some glider tow
thanks
There are three tubes under the battery box shelf that were on some but not all 135 hp Super Cubs. A.E.R.O. has an STC as does Cub Crafters for the 180 hp engine in the Super Cub. I believe both require Cleveland wheels and brakes, flaps and balanced elevators.
