RE: wemotec 480 EDF pusher prop
The mega 16/15/2 or 16/15/3 is a good, inexpensive brushless setup that can be used in the minfan. Typically about 8 cells for the /2 and 11-12 cells for the/3. Either will get you about 300-400 watts or so for a total of 600-800 watts. That should fly your A-10 pretty well.
