2Cool RC Plane

Eric builds his 2Cool radio control biplane.

The control horns for the ailerons will mount directly on the nylon hinge, but my experience with the mock up hinges has shown me that with enough force they can be pulled off. So, I epoxy a small sheet of fairly rigid plastic to cover the hinge and the area around to form a better mounting surface for the control horn. Note masking the hinge joint is critical to making sure the epoxy does not get into it.
