Also, the smaller pack makes for a better balance between what the motor needs, and the available energy in the pack: no need for a nuclear power source to run a 17.5t.... No wonder some racers endup cooking their motors, while I run mine at a much higher gearing with no heat issues at all !!!!!!! Take a look at stock brushed motors running nimh packs easily vs burning up with lipos, eventhough the lipos are lighter... Yeah I know brushless is more efficient than brushed, but brushless/nimh is more efficient than brushless/lipo for the same weight..... Don't overcook your motors guys with 7500mah packs while Bert passes you by....lol.... A 4300mah pack is the best size there is....
