Flight Controls (throttle and stick)

As much as I was impressed with the quality of Thrustmasters Hotas Warthog stick and throttle, they didn't feel like real flight controls. So an improvement was due!

Some setups would made the stick jump when moving it a little, others just felt sluggish. Some setups would made the stick jump when moving it a little, others just felt sluggish.
After A LOT of trial and error, I settled on a combination of regular springs and motorcycle oil dampers. After A LOT of trial and error, I settled on a combination of regular springs and motorcycle oil dampers.
That and some added centering mechanisms provided the perfect feeling of a real control stick! That and some added centering mechanisms provided the perfect feeling of a real control stick!

It is light around the center, with increasing forces towards the outside. It is light around the center, with increasing forces towards the outside.
It moves small amounts without any jumping and always returns to its center when released. It moves small amounts without any jumping and always returns to its center when released.
This a video on the making of the throttle and stick.

Hey there Bergison! 
I recently discovered you and your awesome creations, I know you said you aren't looking to divulge your secrets regarding the G/Motion-seat you've made since you are looking for a production company. I was wondering if you would be willing to give out schematics for your stick system? It's incredible and I can probably figure out how to reverse engineer it from your pictures, but I figured I could ask for schematics to make it a bit easier lol
