Bayne [mailto:[EMAIL PROTECTED] Sent: Thursday, January 12, 2006 9:38 PM To: Ed Burkhead Subject: WRB Re: [COUPERS-FLYIN] static RPM RLYFLYIN Hi Glen, For all Ercoupe Models in which the C-85 is approved (which, officially, this engine remains), if it has the McCauley 1A90/CF (elliptical tip) or the 1B90/CM (square tip) Met-L-Prop, applicable TCDS sheets agree on "not over 2225 and not under 2025". It stands to reason if a given prop reached the upper limit before the rebuild, the additional "real world" power from the higher compression ratio and additional displacement would require repitching (courser) to get full throttle static RPMs within TCDS "spec".
