<DIV>Depending on when Advanced class flies, I would give up a morning or afternoon to take RPM measurements from any willing subjects. I would propose measuring RPM and temperature, then record fuel, prop, motor make and model, glow plug, header, pipe, and engine mount type. We could announce it at the pilot's meeting Sunday evening so people could ponder it and be ready if they are willing. </DIV>

<DIV> I'm not sure if it could be done during the Final's sound check, only one person can be by the plane and in FAI the pilot is on the clock so would not want to take extra time for an RPM check. Besides, a condition switch might be limiting max rpm ( did I say that out loud ! ) :)<BR><BR><B><I>Woodward James R Civ 412 TW/DRP/ACQ <James.Woodward2@edwards.af.mil></I></B> wrote:</DIV>
