Hi Netters, I cant find a formula to calculate the prop pitch/rev relationship.For example if a certain engine gives 2000 rpm with 52d/48p at max .what reduction in pitch will give 3000 rpm. ? best regards, Eric, South Africa.

inch reduction maybe to much of a reduction as the prop will unload as the aircraft accelerates generally 200 rpm or so. Rick Human Houston, Texas - Original Message - From: "Eric Evezard" To: "KR News" Sent: Monday, May 07, 2007 9:13 AM Subject: KR> Pitch/Revs.

Sterba's formulas don't exactly give you what you are asking for, but he has made accurate recommendations on his props and been right on with the resultant RPM for me in the past. Anyway, the formulas he has are at: http://www.greatplainsas.com/edrules.html -- Original Message --
