OK, folks, we have the test data.

Temperature: 60° - clear, sunny and low humidity (for North Carolina)
Fuel: fresh Powermaster GMA 5% Nitro, 22% castor/synth blend
Glow Plug: brand new Fox Long (non idle bar)

All props are 11x6. With each prop I leaned the needle valve until RPM's dropped and then backed off a few clicks. So, these are peak numbers.

MA Black:
13,550
6.4 lbs. static thrust
1.15hp
66.9mph

MA 3 Series:
13,477
6.76 lbs. static thrust
1.24hp
66.5mph

Evolution (I chose a prop constant value of 1.15 which is lower than APC, but, higher than MA-S3):
13,146
6.62 lbs. static thrust
1.21hp
64.9mph

APC:
12,853
6.52 lbs. static thrust
1.18hp
63.5mph

Graupner:
12,406
6.91 lbs. static thrust
1.29hp
61.3mph

I'm waiting for comments...
