  • The setup uses a single aileron servo with an offset control horn, EZ-Connectors and pushrods.
  • Pull-Pull hardware, the rudder/elevator is a pull-pull setup including horns and Dacron line w/cable tensioning.

To get these air-frames to balance, you need to mount all electronics forward of the CG and mostly within a few inches from the firewall. This setup is identical to how most competition F3P indoor foamies are constructed. The foamie builds flat on the deck, flipping it over then mounting the servos and aileron pushrods prior to installing the turtledeck and rudder assembly.
