Found a piece of copper tube, so decided to dump the heatsink and make a water cooling coil for the motor.
Where's your source for the copper tube? Think I'll need to stock some.
BTW, I find it works best if you spread some pc heat sink compound on the insides of your cooling coil. A bit messy perhaps but it's great for efficient heat transfer.
For some people it's important to show what they have, for others it's sufficient to know that they have it.

Got it from artfriend...yup, I got some pc heat sink compound too, stole the idea from you....

The one I got from artfriend is thin walled and 'fold' easily. Any trick to prevent that? Read somewhere that stuffing the tube with fine salt prior to bending helps to prevent folding. Tried it and yup, it curves nicely without folding. However, I can't get the darn salt out later. Even soaking the coil for a few days don't help. Now the coil is history...

The copper tube i used is the thin walled type that "fold" easily, use a torch or the cooking stove to preheat and let it cool down naturally. After that you will be able to hand bend it around the motor without the folding problem.
Sorry for the late reply. Just make sure the silver band is towards the +ve side of the motor terminal.
Have you tried connecting the diode across the ESC's motor terminals instead? I understand that in some ESC the diode is built-in on the circuit board, hinking of doing this so that diode can follow the esc wherever it goes...

OK, this is called 'annealing' but I thought it only works for brass tubes. Thanks for the tip!

Hmmmm.....someone did ask a similar question in another thread. Personally I have no answer to that. I don't see why you can't do it this way but lemme tell you I'm no EE guy first!
