Default RsPro with Heatsink mod

I finally got around to to heatsinking my RsPro to use in 8 scale, or use hotter motor without needing a fan blowing onto the copper post.

The heatsink didn't add too much height to the ESC. Sure an RX8 would be better, but the size doesn't work out too well for some applications.

I wanted to add a Round heatsink at first, but it didn't work out too well. I opted for the thermal conductive foam tape on the bottom fets, to reduce vibrations and shock.

Can you explain what items you used and what performance gains you found?

This mod is for those who wish to run the RSPRO in short course trucks and such. Cooler ESC's produce more power, hence the extra heatsink on the bottom fets.

I added two 25V 470uF caps with some TVS's. This helps with the higher ripple currents you see in bigger vehicles.

The pro has the Turbo feature and the smaller size. I have two RX8's, 2 MMM, 2 MMpro, a Quark SSB and they are just too big for some setups. The pro fits the bill well.

You can run more voltage with an external bec.

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(4s A123). 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.
