Another performance update on my MLD 28, more prop data. Moki wood 16 X 10, up to 8700 after 20 minutes more run time.

XOAR 17 X 10 = 7350 RPM
XOAR 18 X 10 = 6800 RPM

It was 32 degrees today and the engine ran great with the 18 X 10 XOAR, on a 14.5 lb 1/4 scale H9 CUB. I do not have a 3D plane to test it in but this engine was pulling the CUB around fast and had good vertical.
