I got me a used RSPRO to run in a 1/8 buggy. I don't want to run a fan, so I opt for a heatsink.

The first pic shows the lowest profile setup and covers all the fets.

Second pics shows a cylindrical gangster heatsink. Would be easier to put on, but will increase the overall size.

I also have some 1 Farad 5.5V caps. Would be good for 1s setups or put two in series and will be good for 2s setups.

Probably it would be so. But I worked enough on my minitruck and really didn't want to get into another liquid fuel hobby.

I like the round heatsink.
That will look sweet sticking out of the bottom of the ESC case.

Thanks man. Filing the plastic to make the heatsink fit perfectly took the longest. Almost look like a upside down speed passion.

I put the RSpro in the CRT.5 instead, pushing that 2500kv LRP motor. Used a dimension engineering BEC and Luciano 25V cap bank. Using Throttle Profile 3 and like it alot. Temps on both the copper post and heatsink were the same @ 104F after one battery pack. Brakes are typical Tekin and just the best. Pinion used is 15T. I used some more Thermal foam tape between the heatsink and metal plate. Used a wire to keep the ESC in place during impakt. Now I just have to make the wires look pretty.

It looks great and will look even better once you get those wires cleaned up....104F sounds like you can go up 4-5 teeth on that pinion. I'm guessing that the motorwas ice cold.

Ran it again today. Motor was at 160F and ESC at 125F. Caps sat at 105F. This setup is sweet. Need to make me a new setup of foam tires for the CRT.5.

Yea, it's nice not to have to use a fan to cool the RSpro down.

yup. That is basically it. But I used the double sided thermal foam tape to keep it on. I did not want to use the thermal epoxy.

Then what about the fins ? They just floating ?

What if you use that metalplate as its heatsink and use a solid aloy piece instead heatsink fins and use Thermal Tape and tape it down to the plate using the plate as the heatsink ?

ahhaha Use the car itself as the heatsink LMAO xD

Hate to figure out what i wanan do with mines.

Yup they are just floating. I have it like that for when I want to stick the esc somewhere else. For now the fins make contact with the bottom plate with the use of some more thermal tape. So yes, the plate also becomes part of the heatsink and takes care of isolating some vibration.
