The always awesome joseico90 at rcgroups has a nice tip for easily improving the efficiency of a blue wonder motor.

with this mod to improve cooling I'm managing 11Amps for 20 secs periods doing the odd hover 

Blue wonder 1300KVAbout 110 watts on 3s 460's packsAnd the biggest slow prop I could, a GWS 10x4.7 

I love this set up for slow aerobatics on my 30" Big Blue
