Ok, heres the deal.
Had an X-45, the throttle unit seemed to go bad. Throttle was spiking, rudder was spiking, it was doing bad things. So, I tried to fix it, and ended up basically destroying it.
Fast forward to a couple weeks ago. I buy an X45 off Ebay for $40. Of course, the stick is broken when it gets here.
When I hook the broken stick up to the throttle that came with it, the throttle works fine. When I hook my old, functional (mostly) stick up to the new throttle, nothing happens. If I detach the new throttle from the old stick, the stick begins responding again.
Any idea on what could be causing this?
