This engine was used to power a big Red Zephyr free flight model which was modified for 3 channel radio assist: rudder; elevator and engine cut-off. The engine flew the plane adequately but could not ROG and had to be hand launched. The engine was later replaced by an O&R 60 which had more than enough power for the job. I have since sold all my ignition parts such as miniature coils and transistorized circuits, so I had to resort to using a surplus motorcycle coil and ignition battery.
