Richard,
That's a strong motor you got ! AI sent my Biela 26x8 for a totaly different motor yesterday, I sure like these propellers.

Load that Brison down !! 7100 - 7200 sounds good, I ran a Zinger Pro 20x10 on my Hurrican and it was too much for it. Only got
about 6500 RPM and the 2.4 lugged on the upline the motor didnt pull at all at that RPM. Changed to a 20x8 carbon and ran
around 7300 and the motor was happy. if your getting 7100 static on a MA 20x10 that's a really strong motor, thats 3.2 numbers !!
Watch your temp if you have it cowled really tight, they don't like to run hot, I had to baffle the Hurricane to get the temp down below 179 degrees.

Happy Landing !

JDS
