Look what I found..

Looks like he must be using a 1527 1d. 2300kv seems like a poor idea, why not go to a 1527 1y at 1250kv and use 6s lipo? A pair of 4000mah 40c 6s lipos in parallel would provide plenty of power and the amp draw would be cut in half over his setup... And from what I can gather the Y wind motors are better. Interesting idea, especially if he added options to go with an even lower kv motor so that people could run 6s and do 70mph or so.
