The Menz Ultra spins a lot, but I've got better pull from an APC.[X(]

I have to admit, I haven't done much experimenting with props in this size. I've just recently started buying lots of different props in this size.

While a specific size and pitch from Menz or 3W may work well on 1 model--it may not be the best for another model.

I was surprised to see the blade width on the NX and MSC props. Much wider than I expected. The Menz Ultra and the APC look like toothpicks compared to those others.

We're gonna find out in a couple weeks. The engine needs more time on it. It hasn't been run much, so I'll be propping for closer to +/- 7300RPM at first. Run it like that for 6 or 8 gallons and then change the size or pitch. I'm really eager to put that NX 21-8 on it. I think thats gonna be the one that gets the RPM up where I want them--but only the fish scale will determine the thrust.
