Control horn

Here is my conrol horn for Rc airplanes
Has 20 mm height enough for aileron control of my glider (3D printed:see https://www.thingiverse.com/thing:3648375) or foam airplanes

Since is deseigned to be printed without support the horn is not symmetric and I added right and left version.

Print at 100% infill with at least 2 perimeters.
Best with ABS or PETG but I used also PLA.

Installation:
Open a square hole in the control surface and glue the control horn in position. when glue is cured remove excess material on the opposite side of the control surface.

As usual if you find useful consider to leave me a tip...
