Thats what I figured but, you can't tell that to some people in my club. They don't get that like electricity, water takes path of least resistance.

My 2 new UL-1 motors came in.... time to add some extras...

I burnt them out of stupidity, too hot of setups on 90F day.

Position of jacket:

-at the end of the motor towards the wire leads: not good

-in perfect conditions water jacket should be at least have the length of the magnetic backiron section within the can and be positioned right over it to cover this area. This ensures best heat transfer.

I've seen Terry Davis add a homemade wire cooler. just block of aluminum with 3 holes for wires drilled through it, then cut so 2 bolts can clamp it to the wires and a last hole with a tube to flow water through. It was pretty neat. I might make a pair.

Yep, I know that guy. I saw him start a car once with a 4S lipo. He is a very cool cat.

So, another guy at the club had a heat sink on the end bell of his motor. Great idea. He was running a pretty big prop and it didn't seem like he was having temp issues. Might want to consider something like that. I might even try screwing a nitro motor cooling head onto mine! ....or a marine nitro cooling head w/water cooling.

I've started my 99 Pontiac several times with a 1/2 charged 14.8v lipo pack. Not a problem but, I don't reccomend you do it.

Just something to think about with these jackets. It seems that if the ID of the jacket was a close fit to the motor can, we could get transfer of heat from the motor to the jacket by direct contact (heat sink). Advantage here is that the water flowing through the spiral passages takes heat from both the motor directly (bottom side of flow) and the jacket (top side of flow). One step further, making the jacket out of a better heat sink material (Cu?) would further help. I'd be curious if anyone else agrees. I could machine up one of these, but Cu is extremely expensive, and it would probably take me an easy 3 hours.

Would life a set of these for my Lehner 2250's
