BME prop selection
My buddy Dave Genovese loves the Menz-S 27x10 with his BME 102 evo and his DR-109 (23 lbs). Turns 6200 rpm on in-cowl mufflers. It's fairly quiet with great pulling power.

I havent tried the Menz yet, but I have tried an Airwild NX 26x10, and a Mezjlik 26x10. I went to the mezjlik based on opinion here, and it runs about 500 more rpm than the NX, about 6500, which appears to be the sweet spot for thrust and torque. I like the downline breaking better on the NX, also the mezjlik is quite heavy. If the Menz will produce the right RPM, it could be a better way to go.

Yojedi, what you want to see is an rpm in the 6200-6600 range on the ground. If your prop gives you that reading, and pulls the aircraft properly, then use it. There is a plethora of props available now, and though they have different pulling and braking characteristics, they will all do the job. You just need to get one that "feels" right.
My current Evo102, with Pefa Canisters and only 3 gallons of gas through the engine, and still set rich enough to burble in flight at low midrange, will easily turn a Menz-s 27-10 in excess of 6300 rpm anytime. An AM28-10 prop, available from Desert Aircraft, turns just a hair faster in the 6350+ range, and I expect my Mejzlik 28-10 to have similar numbers when I bolt it on. This IS on canisters, remember.
If you are running the standard BME mufflers, most of the 26" wooden props will work very well. BME has it's own line of props now, btw, and they are EXACT length, not under-sized as the Menz is. They are also a few dollars less expensive than the Menz series and turn comparable rpm figures. Contact BMe for more information, and any answers you have for your questions.

I have both a non-Evo and an Evo 102. My favorite prop on both is the Menz 27x10 S. The non-Evo was turning it at 6100 last I checked and the Evo at 6200 last I checked. The Menz 26x10 S rips on both engines and is too loud. The Mezjlik 26x10 is not enough prop nor is their 27x10.
