The MU2 is "waiting in the wings" at the moment, while I work on the IXEG V12 process. The MU2 works tolerably well enough in XP12, whereas the IXEG does not work enough in 12 to even fly it....so I need to get those customers taken care of and I'm working towards that atm. As soon as the 733 goes out the door (more than a week, less than a month), I'll go back to the MU2 and make another series of passes to leverage the V12 features and start improving the performance model. It won't get left out in the cold.
