CofG calculater

Post by AlexC »

I had lots of fun printing and building this CofG machine.
It was originally designed to accurately display the CofG position for F3F gliders but with a change of wing mount suits a larger range of models.

When set up and calibrated it is very accurate.

These photos show my Walrus glider on the machine. According to the manual, the correct CG is 71mm from the wing root fairing.
As you can see from the photo (hopefully) mine balanced on the point with 5 grams on the tail.
