Dave;
Gee I'm sorry, I did not take reading. I was using a mejslik 20-10 & just not getting the performance I needed on a 17lb edge. While at field a mate was using a BME 50 and had this BME 22-8 prop & he changed to a 22-10. I bought the 22-8 (BME prop)for $18. On a whim I put her on the 44 & had significantly better performance with the plane. Because it was a whim, I did not think to take rpm, but ear said it was not significantly lower. Hope this helps.
