Possible idea for bringing brushless to the pit party (as in racing)

[MetalMan]

Only problem with using a capacitor to recharge a battery in a short amount of time is the current. If a 2000mah battery/capacitor would get you 5mins, it would take 1,440amps to recharge in 5sec., if I did my math right ( 5sec = 0.0013889 hours, 2Ah / 0.0013889 hours = 1,440amps). From my knowledge of what's currently out there, I'd say we're pretty far off from that.
