The only limitation I don't like is that 2050rpm to 2350rpm must be avoided for torsional vibration reasons. I do not know if this also applies to a C2C, but it probably does. It just means that I cruise at 2400 rpm when I would prefer to run a slightly lower rpm and higher manifold pressure. It also reduces prop to ground clearance by 1/2 inch as it is 1 inch larger in diameter than the Demuth. Takeoff performance and initial climb are greatly improved over the performance with the wooden Demuth like yours with which I had been flying. Max performance at altitude is identical with either prop. I don't know how to get an MT without paying through the nose. I bought mine through Lancair. The prop arrived as promised with one defective part. The wire leads for the bolthead rpm counter had been damaged where they emerged from the nylon brush holder block, apparently when the potting was trimmed.. An E-mail to Germany got me a whole new assembly by overnight air at MT's expense. I also got good rapid responses to questions about some of the fractured English translation in the otherwise excellent manual. It added about 20 pounds over the flyweigh Demuth but all usable airplane loadings stayed in the CG envelope with no other changes. I think it is worth the bucks. Ross W.
