Mornin' guys/gals,
Our -6A (Sojourner) now has 36.5 hours of the required 40 flown off and for the last few weeks have not had the main fairings/pants on.Last week I did a square (North, west,south, east) pattern at 7500' and WOT or 75% and managed 180MPH with our 0-360 and 3 bladed Catto prop, which Craig pitched for max cruise....turning around 2650 RPM.
Then we installed the main gear fairings and wheel pants coupled with Bob Snedaker's intersection fairings and WOW!!! At 7500', the RPMs climbed to 2725 and the 4 way average went to 196.5MPH on the GPS...way more than I thought we'd get. The temperature was about the same as the earlier test and I'm really happy so far, with a few insects on the leading edges and no paint. I repeated the square pattern at 7500 feet and 2500RPM and still averaged 182MPH......nice. The airplane has the later style 'sheared' wingtips and weighs 1046. Are these numbers pretty much what the rest of you have found?
Regards,
Pierre Smith
ps The climb rate also increased by approximately 250FPM! Pleased, yes.
