OK here are a couple of more readings

The same ZDZ 50 NG as in my previous posts on my DP Edge
MSC 22x8----6700 RPM
Nice prop, quiet, pulls nice at lower RPM and unlimited vertical-not as fast as the Menz but much better than the Prozinger Or Bambula

Brisson 3.2 with about 30 hours of running i just aquired on a WH Extra Speical--17.5 pounds
Mejzlik 22-8 Carbon Fibre----7200-7300 RPM, Unlimited vertical and very fast in an upline, even on the heavier plane!! Nice combo!
MSC 22x8---6400 RPM quiet and nice pull at lower RPM , Vertical is unlimited, steady but not fast--now the weight and slightly less power than the ZDZ start to show. IMHO, just a bit too much prop on this heavier plane if you like to go straight up alot.

Got a couple of 3W 22-8's coming and a Mejzlik 23-8, will let you know
