Compact collective head

Summary

This head is perfect for motion platform users, as it can be used without a counterweight, or even without the pneumatic mod (although I do highly recommend the latter!). It also works well, as a generic gaming device – The shape allows using it as a throttle lever on a single-engine airplane when mounted to the GUNDE chair onto the Malinda mount at 30 degrees.
