I use this motor coupled with 6x3 prop on my Bixler.
Power source - 3s 2250 Rhino
Flying weight - 730 gr
Current at FOT is 18A
I tried also 6x4 prop (I noticed no difference between 6x3 and 6x4 in thrust but current was a bit more in second case and pitch speed was a little more too, so I recommend 6x3 prop).
I cut about 10 mm of foam and made plywood motor mount (trying to keep motor spindle angle as intended by designer).
As a bonus you can change motor spindle angle adding more nuts (or washers).
You should use thread lock to fix each nut.
