Hey guys, so I wanted to try something to help cool my leopard 5898 1100kv. She does get hot if I do too many wot runs.

Anyway, what I am attempting is to use another heatsink with thermal pad in between the motor and the heatsink to transfer the heat.

To make sure I have the best "connection" possible, I riptide and rubberband-ed the heatsink and thermal pad onto the motor as firmly as possible.

Think this will work?

I've had a thermal pad like that on my Hyper vse heat sink its been fine for me for months.

Were your motor cans finned?

Perfect, can wait to have better heat dissipation!

I also did this on my stock kraton
 
Nah the can is smooth on mine, but as long as the pad is making good contact i'd think it should be ok.
 
A few dabs of thermal epoxy would hold it on there nicely.
 
Are you saying put thermal epoxy in between motor and thermal pad or replace the pad with thermal epoxy.

Wouldn't that essentially permanently mount the heatsink to the motor?

I meant between the the thermal pad and the heat sink, but if the elastics are there to hold the whole thing down on the motor then that doesn’t really help.
