brushless 1/5 4wd conversion about to begin! couple questions.

[Ryu James]

what are heat pipes? are you guys just referring to the 8 pipes on the esc?

what about this? i thought if i could find some kind of little pump i could mount a small nitro tank on the chassis with some coolant/water in it and use fuel line to pump through the esc pipes and back into the nitro tank. i just dont know where i would find a tiny pump like that. i am just gonnna stick with the fan but this would be kinda cool.

How about a washer bottle motor from a 1:1 car, pumping coolant?

cool stuff, each layer has it#s cooling.

one possibility would be to remove the pipes, grind the remaining surface flat, and put a heatsink on each side (w/ thermal glue). but this would probably void the guarantee. and is too much work.

or you could get yourself one of those water cooling systems for rc-car motors. yes, I'm not kidding!! I've seen them already a couple of times on the internet. It's mor or less the same like 1:1 cooling systems. and you have plenty of space on your car. water is actualle much better for cooling then air. here we go:http://www.rcuniverse.com/forum/m_5375253/tm.htm
get that and you have the most unique bl-converted truck on the planet!

an other strange but probably effective Idea:
you get massive aluminium (or copper)-sticks which fit tightly into the tubes, probably together with some thermal paste. the sticks would be longer than the tubes, like that you have more surface. maybe you make the ends of the aluminium sticks flat, so you can glue a cpu-heatsink on it. like that you have much more surface for cooling purposes. and it can be removed easely.

or you put a little fan on each side, right on the tubes. so the fans cool - instead a heatsink - the tubes. it would look a little bit like those mgm esc's.

Ryu- This has been done before when a guy used a boat ESC in a vehicle. I'll try to find the thread on his build. He said it worked very well. He used a small pump that put out like 10psi and a small tank.
