best way for cooling motors and ESC's

[joey_picus]

In my case the fan would be a good aural indicator that the robot was switched on! (I keep not seeing my antweights' power lights and letting the batteries drain to uselessness, heh)

keep doing that with my dx6i

i use some PC style fans from Maplins wired into the power line, about £5 each i think. they work okay but i have been thinking about some type of water cooling system...
anyway yeah, work okay as long as the robots not massivly hot, if you have the weight/space go for it
