I don't know the kv of the 8 turn.

The 2250/10 is 1184kv. 8s lipo... (assuming a 3.5v per cell under load) would be 28V, which is only 33K rpm. I can't imagine the 2250/8 would be out of range at 28V... what's the kv??

here's an interesting quote from a post I found at rczone... "I don't know if a car could really go much faster with that same power setup. That boat was actually flying over the water with only the prop and rudder touching the water. This means it probably has less drag than a car at comparable speed. FYI-that was using a Lehner 2250/8 using a 32.170 schultze controller (32 cell, 170 amps continuous, water cooled) This setup spun the 2" prop at 47,500 rpm, producing over 3000 watts. Still, a car could probably go pretty fast on this setup, which would probably require a custom chassis, due to the fact that he was using 32 GP3300s, instead of the AA or smaller cells that the really fast cars sometimes use.
