The beila 18x10 is a very heavy load for the DLE 30. I could only get 4,400-4,500 on it with a bowman ring.
MTK the 33 may be strong but it drag it down a bunch also. The Beila is = to a XOAR 20x10 laminated prop or so I have been told.
The few Bielas I've seen were better suited to converting power to noise. The Mezjlik 18x10 carbon 3 blader is indeedabout the equal of a 20x10 2 blader. I am now using the 20.5x10 apc 2 blader on the piped 33....7300 rpm happy happy and just a hair off the rpms of the 3 blader....AS always, YMMV
