>What kind of runtime do you get with hard running like that. What speed are you geared for?

Runtime hovers between 6.5-8 minutes when driving this way.
. 10s1p A123 (2300mah) setup: Eagletree logs showed: Average amp draw was between 18-22A @30V -> 550-650 Watt average.
. 6s2p A123 (4600mah) setup: calculated from runtime the average amp draw must have been between 35-42A

Gearing:
Both truggys were not geared properly for those short straights. Motor temperature was too high.

. 10s1p A123 setup: 1:14.56 and the motor reached 32000rpm. Calculated top speed: a bit less then 40mph with ballooning badland tires.
. 6s2p A123 setup: 1:15.11 with an estimated motor rpm of 38000rpm. Calculated top speed: a bit more then 40mph with GRP Grip tires.

While driving we both said that the 6s2p A123 setup was a bit faster. But this is hard to tell when driving on such a small place.
