Danny,

I'm using some Kokam 3s 3200mah like the ones Greg recommended in this thread. I don't know if it's such a good idea to use those on the stock motor for any length of time though. I have a sneaky suspicion they burnt out my original motor over time. I also may need to switch to a 4S2P setup on this plane if it doesn't have the power I want. I should know tomorrow. Air scoop is actually the top half of the spinner that came with the stock motor package. Just cut it half with my dremel and mounted it for extra cooling for the AXI.
