I was curious about rpm numbers myself. Keith originally said the 110 'xtreme' was gonna turn a Menz 28-10 400 more rpms than the DA 100. The guys flying the prototypes haven't seen anything like that yet...they may still have some work to do on it to bring them up to the numbers they claimed... not sure about that though. They may just settle for what they have now and drop the 'xtreme' pitch.
