Just got a used BME 44 and I'm not sure of what prop to use. It'll probably go on either one of the new Skyshark Cristen Eagles, or a BME Pitts Challenger. I was thinking about a 21 X 8 Menz standard or Mejzlik.

A 20x10 or 21x8 would be good for this engine.
Keep the RPM's up over 7200 and you should be fine.

By far the best prop I ran on my BME44 was the mens 20-8. Giest is right, that engine needs to spin up.

echo what joe said, the best prop i had on mine was a menz 20/8...turned up over 7500, and pulled hard.
