Thanks Tom, I offer the swap as a service. There is machining involved and it is always cheaper to send me your gear than buy another set already set up. So if you want to have me do it I suggest the off season. Yeah, the CG machine is awesome. You should see the prototype flight computer Gaspar (Xicoy) sent me to test out. It is BA! Has a g meter ambient air info and all your turbine data and hand held data all in one screen that stays in the jet, and it outputs all the info back to your radio. I'm testing it now in my L39. Pretty sweet with my Jeti systems and the JC Rhino.
