Servo Screw-Mounting Rings for Foamboard Airplanes

These 3D-printed servo mounts allow you to mount servos in your foamboard airplanes with screws so you can remove them later for replair or replacement, or just to move them to a new plane.

I've never felt good about using hot glue to mount servos in my foam board airplanes.  The servos can be removed with a knife, but it's an ordeal that damages the plane and leaves a messy task to clean up the servos if you want to re-use them.

As I was prying the rudder servo out of my FT3D-120 for the third time to replace gears, I thought that there had to be a better way.  So I sat down and designed some mounting rings to provide hard mounting points for screws.

Just hot-glue these rings into the plane and then mount the servos with screws.

This version of the ring was designed for common 9g servos like the HXT-900 and the TG9e.  It may work with other servos of the same dimensions.

If you have a 3D printer, you can print them yourself.
