I got hold of a Menz-S 15x8, but I haven't had a chance to try it yet, maybe later today. So far, the only prop I've flown has been the 16x4W.

I tried to get a 16x6 Menz, but the distributor didn't have any. I'm going to order a 16x6 Bambula from RCShowcase and hopefully try that next weekend.

I'm not unhappy with the 16x4 APC, but it does seem to unload and over-rev in the air, even at 1/3-1/2 throttle. Makes the YS sound almost like a two-stroke, you can't hear the exhaust note over the prop sound.
