Control horn

thingiverse

Here's my control 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 it's designed to be printed without support, the horn isn't symmetric, so I made right and left versions. Print at 100% infill with at least two perimeters. Best results come from ABS or PETG, but I used PLA too. Installation is a breeze: open a square hole in the control surface and glue the control horn in place. When the glue is cured, remove excess material on the opposite side of the control surface. As usual, if you find this useful, consider leaving me a tip...
