I'd like to replace my shifter handle on my X but I'm coming up with nuthin. I'm looking for something with 2 or three buttons to control VDC, OD, rockets, etc. I actually have a control stick grip from a helo (or something) that I got at a surplus store but without some major work and machining it's pretty much useless. Are there any replacement that you guys know of? Have any of you done this?
