nah, I checked with them offline; they're not making a muggy chassis (the new kits are all tekno specific chassis), but the mount will work with most anything; you just have to drill mounting holes in your chassis, assuming it all fits. In the right spot that is....
I like the tekno b/c it supports the whole motor, which is good for:
-the gears
-minimizing chassis flex
-less stress on the motor
BUT, it isn't out yet, and I may mess up those holes that need to be drilled, and it does add even more weight to the muggy (though only ~2.5oz), and it has to cut down on cooling (though it won't matter much with a finned Neu). RCM mount sure is easiest though.
