Hi again everyone, I have more questions! Revmaster hasn't responded to my questions, but Warp Drive has. So I'm making a little progress!
Here's a brief history. The airplane is a standard KR2 with spring gear and brakes. Beyond those changes, it appears to be plans-built. It is fitted with a Revmaster 2100D and a Warp Drive 3-blade prop, square tip, 52" diameter. I am soliciting suggested RPM settings, pitch settings, etc. I note that the Revmaster charts stop at around 3300 RPM, but that the curve is still rising at that 80HP point. Daryl at Warp Drive suggested that I should be looking at perhaps 3500-3600 RPM ??? He said that if I want to "slow it down" to 3000 RPM, some pitch adjustments might be appropriate. So I guess I'll ask for the simple information now, and then the detailed stuff later! What would be the redline for the 2100D ? What would be the best takeoff RPM setting ? What would be the best cruise RPM ? (And dozens more questions like that)... On the prop, what would be the best pitch, at least to start from ? Has anybody worked climb against cruise performance and developed some suggestions for pitch settings ? Any information and/or suggestions for this engine/prop combo would be most appreciated. The aircraft has 118 hours logged with this combo, but very little performance data is documented. The original tachometer had the redline at 3500 RPM, however Warp Drive is suggesting the 3500-3600 range for normal operations, so I'm wondering now. I am trying to develop a POH and also determine some do-not-exceed markings, etc., so any experience in these areas would really help. Thanks, Dave.
