I killed a saitec st 290 pro .. for the main controller board , 8 way hat , lower buttons . then put all that into a mad catz panther joystick .
the potentiomiters are far superior in the panther so i used those .
for the rudder peds i used a pot from a old tm stick and connected it to the saitec board 's previous (twisty) rudder connection .. using an old game port plug (the panther stick used a game port plug previously for the rudder connect .
i placed a disc on the pot then made a sloted bar that connects to the peddle main tube as for it was too sensitive and needed some built in freeplay . I added 2 more springs to the disc to hold it to an auto center .
the foot pads rotate about 30 deg's total because i sloted and added a post for a stop .
So far i have no spiking ... but i do get and off calibration every once and a while in the peddles ,I'm thinking twin pots in series may be the ticket here . I have another set of peddles that work this way and they were rock solid cal wise .. but there action is very hard to do comfortly . (they are sitting on top of the toolbox )
So these are my 1st set i made .. just a tinker project after work ..
( yes i bend,weld,beat up metal all the time )
I'll make another set soon but with lots of improvements .
a bearing instead of bushing in the center pivot for starters.
Design brakes , along with the main springs hidden underneath .
Then make adjustable spring rates, main stops, ped angles.
for interface it programs the same as a saitec and connects usb .
i had to make schematics for bolth sticks by hand and ohmmeter .. (Yes i wrote to bolth manufacturers and searched the net for weeks for them)
