Progressive spring characteristics for Thrustmaster Warthog Hotas

[PicksKing]

Hello,

 

maybe some of you, with a Thrustmaster Warthog already looked for some modifications. For sure you realized, that the spring characteristics is nearly linear. Even with a 10cm extension this feels a bit unnatural. So I thought about to replace the spring, but not only with a softer one. What I need is a spring, with a very low spring rate near center/origin and a high spring rate in higher deflection. So I need a spring with progressive spring characteristics.

 

For illustration take a look on this chart. I need the green one. Blue is standard.

 

 

The question is, where to get it? Are there maybe available modifications, which I didn't find?

 

Thanks for competent answers.
