Hi Guys,when looking at the MAAM SIM R4D-6/DC-3 manual, the METO power Manifold Pressure is quoted at 43 and a half inches on the Pilot's side placard, but stated at 41 inches in the "Take off and initial climb" chapter...What is the best value ?Regards,altack

42.Sorry, couldn't resist.I should go with the higher setting. That's where MAAM-SIM has it in the checklists too, and what Russ Strine (MAAM boss and pilot of the R4D-6) himself recommends. And clearly, it's the correct relationship between RPM and MP that really matters.Mark "Dark Moment" Beaumonthttp://www.swiremariners.com/newlogo.jpg
