A horn for control surface of radio-controlled gliders and planes

This is a parametric control horn for radio-controlled gliders and planes.

Edit the included OpenSCAD source to change any of the parameters such as:

- Number of holes
- Hole radius
- Height of the first hole above the surface
- Overall thickness ( strength / weight trade-off)
- Length of the base where the horn is attached to the surface
- Amount of the base to push in to or through the control surface
