ESC cooling

[H&YRACING]

I've modified the existing cooling blocks. Milled out as much as possible from the under side and plugged up the holes to make as big a cavity as could be made. Then glue the cooling block back on. I use glue because the tiny screws usually break trying to unscrew them.

I think most of our water cooling systems are miles away from where they are needed. Even the motors. It's like we cool the hood of the car trying to cool the engine block.

Ray, I used my castle link to program it and also check data logging. When I get home I will see what version I’m running and all the setting and screen shot them for you. I been loving it so far. Mine isn’t waterproof either. I can’t decide to use corrosion x or silicone conformal coating?

Excellent, thank you! I used DP270 from Steve at OSE.

I think the whole case of the esc is a heat sink. So the two pipes coming down the side take all the heat from the heat sink, paste, post. so the more cold water you move through the pipes the more heat you remove.
Sooooooooo Made a manifold out of pvc pipe ( boat stand stuff ) two in lets from the rudder four outlet for the esc and motor then four outlets on the outside of the boat . Temps are 90* on the esc, 95* on the motor, 104*on the end bell bearings, 100* on the motor esc connectors. 1500kv, 2016/3 PL wildthing mono.
3.5 min run.
Cheers, Jay.

I concur. The can on these motors doesn't produce any heat. The dream would be pipes passed through the stator itself. Not very practical though. We new a guy that built a cat with the motor mounted in the tunnel so that it got water and air splashed all through it. Was nutty but ran cool for sure.

Mike, I never looked at the BEC voltage on the FC. I think my receivers do that too. Just haven't been looking for it. I've been trying to stick with Castle for the interchangeable factor. I drenched one in the mono on Sunday. Water line. DOH! Was able to swap speedo between a couple boats to keep me racing because everything is the same.

My reason for messing with these at all is cost factor. Flycolor and the Raider are inexpensive but they have to work. We're overheating them at less than their ratings. Well.......I think we are. I haven't logged......checked......and then swapped in an FC. I may have time to fart around with one tonight.

Ray, I always use this crap when I'm putting cooling on my XLX. I would use it on the FC too. Way better than the thermal tape.

Now that I think about it..........the stator is held in place in the can with a tiny bit of glue that's wicked in between the stator and the can. So the actual transfer of heat will vary from can to can and from motor to motor. It's not a perfect contact point in there by any stretch.

Ray, here how I set mine up.

The stumpfab version looks sweet but this costs maybe $6 total.[

Nice.

Well. All for naught.

Ran it Saturday. Thermalled on the cool down lap. The 150 slows down instead of stopping like some do. Checked the temp. 121 degrees. Next run the power cut out happened on the 4th lap with less prop. Toss that one in the dumpster.

Terry, here is a raider super cooler I knocked out based on Mikes idea above.I have no empirical evidence of “super cooling”. I could make another for you if you get desperate.

I just wanted more reliability out of these. I was going to try better cooling to get it. Didn't work for my application.

There's a shortage of Seaking right now. Rumor is that all the stock is being bought up by one guy that works out of his garage. So nobody but he has them or can get them. Zero chance I'll buy them there. I could put Castles in everything but that's pricey, overkill, and almost as hard to find as a Schulze these days. Yayyyy covid! Nice to have data logging though.

Terry, what you running the 150 in?

Looking around what is available, seems high price or comes on the slow boat.... and yes I would not either...
