Great for the money. Fit perfect at my 28/48 mm motors in my Traxxas Villain.

For the price its OK but I do question some aspects of the design. Firstly a change in O ring spec would make a difference. If your motor is much over 28.1mm you will have problems getting it to fit. My motor was 28.03 and while I got it on by reversing an end without the o ring on first to act as a guide and then repeating that at the bother end the cooler is SO tight I cant even turn it. But the biggest issue is the gap between the cooler and the motor. In my case this is less than 0.4mm. This tiny gap creates too much back-pressure at the other end meaning that the flow of water through the ESC is heavily reduced. Even with a dedicated off-take behind the prop the through flow is miserly - just a dribble.So sufficient to work but playing with fire IMO.

A bit hard to fix but some lub on motor do the trick.

The jacket itself works as intended. As everyone knows by now, the clearance between the jacket and the motor doesn't really leave space for the o-rings (which is the ONLY reason I knocked off a crown). I skipped the o-rings and semi-permanently attached it with RTV gasket maker.

Nicely crafted water jacket - thin light and strong - a little difficult to fit to the motor (very tight fit) but once in place the fit is excellent as there are no leaks and a nice cool engine

Would like to tell that it fits to my XK2845-B-2000kv Brushless Inrunner, unfortunately the engine is still on the way (for long long time). But I used the cooling on another 28 motor without problem, so hope it will be the same.

I couldn't get it on with the o-rings in it. I used rubber gasket maker on it and it seems to be working. Seems to do a good job though.

Rcvd my water cooling few days ago..it is very nice piece of work..not really easy to install on my 28mm motors..need to give wd40 & some grease on it and the motor too..so it can fit perfectly & avoid any damage..the diameter is just too small & im afraid the motor will not have enough water supply for cooling purposes..all and all satisfied with the purchased..thanks HK..
