Somewhere out there there is a review of an electric conversion to a sportsman aviation 30 waco. Is this the ARF you are using? The author thought the plane should be sold after a few flights, way fast landings, a scary litte thing w/ weak landing gear.
I dont know if this applies to you. The wankel is a nice motor by reputation. It would be a shame to wreck it on a skittish plane. good luck
