Joystick Throttle

[linuxman]

I have one of these Generic two stick joysticks, like a Playstation controller. It works great except that the throttle will not stay put. I have the throttle set on the second channel, but when I calibrate the stick it sets it at half throtle, and when I push it up or pull it back it returns to the half throttle setting. Is there a way to make that thing stay put.
