Just purchased your extra 330 kit (fd003_extra330l-arf) .
I hope you can help me with battery and prop size .. the manual was very vaque.
I am using the bp motor a4120-7 and hoping to be around 800 watts.

So I need to know if 3-4-5 cell lipo and what size 3000-3200-mah etc.
I assuming a 12-13 inch prop but not sure what pitch.

Any information would be good , thanks .
