What was the term that was coined by the old pilots? Something to do with the castor oil, scarfs, and having to run to the crapper the moment they land.
On the 100, with an APC 14x6 I hit 10,500 RPM. I adjusted the radio end point to keep it below 9600 RPM. Man could that motor and prop move the Cub. Now I just use the Evolution 15x6 on it, looks scale like, sounds scale like, and flies scale like at half throttle. Really good combination for an over powered Cub.
