3 Racing Heatsink/Fan
 

I just picked one of these up but they do not come with any install instructions. I searched the site but did not find any info. Is anyone using this that can provide some insight?


Thanks.

clamp it on motor :weird:

what XingXing said..and plug it into the reciever.. :rolleyes:

if its got a fan you need to solder the fan wires in, i soldered mine direct to the wires cummin off the cells into the speed controller so its always on when the batts are pluged in

plugs for the reciever are already installed...
just plug and go.

no i had to solder mine to the battery wire

i suggest you dont use the fan. unless you want a fried ESC/servo and receiver. look at the wire on the fan side, they are exposed and so close to shorting with and slight movement of the wire :weird:

ive been racing that for ages it might not be as tidy as it should be but thats cause im in the process off a strip down hence the fact most of the car is appart i just chucked it on to show you that i had to solder it onto the wires thats all. also where are they exposed?

look where the wires connect to the centre of the FAN ;)

They are attached on a PCB. If the two contacts were to touch, it shorting out would be the LEAST of your worries.

Ah ok thats what I was looking for. Thanks for the info. I know you have to clamp it on the motor ;) but I wasn't sure where I had to solder it to.

I found the original cooling fan on the 3Racing heatsink a bit too small and it cannot rotate if when I use motor with strong magnetic. I changed it to a bigger 5v fan and connect to my receiver. I need to change the way the fan mount tho - to avoid the wires touching the ground. Basically, the new fan can blow more air into the comm area rather than just the motor can. It helps when I run 23T stock motor (super hot after 8-9 mins of run time).

So this fan pretty much is no good? i was thinking aboiut buying it...

I don't know about this fan but I love my coolcanfan! :nod:

I`d have to agree the 3Racing fan isn`t the strongest but for US$5 what do you expect.

I`ve mounted the fan so it blows into the comm, rather than onto the can.

Cheers
