4X spring (4 times the resistance than HOTAS COTS) for Thrustmaster HOTAS WARTHOG 30CM or 40CM Joystick.   This spring has @ 4X the strength of the spring that comes standard with the HOTAS.  Fits under the dust cover.

See also the custom spring we developed for 10CM or 20CM extensions which is @ 2X more tension then the spring that comes standard with the Thrustmaster HOTAS Warthog joy stick.  Thecustom spring for the 30 or  40CM extension is roughly 4X more tension.  This 4X spring has over 50 engineering hours in development. This 4X spring was designed specifically for a division of the USAF using the HOTAS for training fighter jet aviators.  The USAF is in no way, shape, or form endorsing this product.

Please also see separate listing for the 40CM extension and cable only, and the separate listing for the 40CM extension kit which includes the 4X spring, the 40CM extension and the 44cm extension 5 pin DIN cable.  We also have three separate listings for 10 CM, 20CM, and 30CM options.
