I'm not sure why there is not a dedicated section for just engines.


But I use to make water cooled copper tubing and small pump for when I use to modify power wheels for my kids back in the day when I was running 24v or 36 through them.

It worked and kept them from burning up to get more speed out of them, lasted for over a year.


I wondered if anyone has done something like this on a smaller scale for there nitro engines ? and if so what they used ?

Or how many have used extra small hollow copper tubing around the cooling fins for more cooling ?
