BME 50 prop
I had a MENS S 19x10 3 blade prop on my BME 50. It would run that prop up to 6600 rpm and that was with only 1 gallon of fuel in the engine. I sold the 50 and ordered the 55 Xtreme for next season.
I would like to see someone make a 23x6 2 blade prop. This would be the ultimate prop for this engine on a 1/4 scale plane.
