Two weeks of prototyping and 3D printing. Say hello to version 3 - 737 throttle mod!

This very nearly did not happen! I soon realised that I could not make a replacement unit to replace the Saitek throttle unit. This was because I wanted to use high-quality pots. It meant a complete redesign and thought it was not worth my time as I want to move on and produce my own motorised throttle unit. Then one of my Patreons asked me to complete this. So the challenge was on.

For those that have a Saitek throttle unit, the first problem you will realize is that they feel flimsy and there is no adjustable friction to hold the throttle levers where you leave them. This is what i cam up with:

This worked surprising well holding the throttle in any position, but it felt a bit too slippery. I then had the idea to apply hot glue to the friction plate and reduce the size of the shoe. This nailed it. With very little pressure applied to the friction shoe adjustment screw, the throttles could be made to physically stop moving until a huge force was applied!
