This setup is what I have been able to do to implement a control line like system using all RC control.
The plane has 28" wingspan and is a BP hobbies flat foamy. It uses a GWS outrunner, 8x6 prop and an $18 speed control with governor mode. The line is very short at 20' to keep the power requirements low. It flies overhead 8s on about 90w. Economy of the system is what interests me. The rest of the system is shown in the video. A video of it flying will be posted here later. I have to give credit to Igor Burger who was the inspiration for this work.
