Introducing the HobbyKing self-circulating liquid cooled thermostat system for 36mm motor powered rc cars.

The Liquid cooling system consists of a radiator with integrated electric circulation pump, coolant tubing, and a liquid cooled motor mount plate. Simply swap out the motor mount, attach the radiator and run 2 cooling lines. The pump comes with a Y adapter to go in between your receiver and the BEC power lead, drawing only 12mA of power to circulate. 

This is great for Scale looks and where air flow could be a problem, and perfect for those that just want to add extra insurance on their investment.

Specs:
Mount dimensions: 47x35x6mm For 36mm in-runner motors (except bibcock’s)
Radiator/Pump dimensions: 45x60x15mm
Total weight: <45g
Power supply: 3.7~5V
Current draw: 12mA

I've installed two of these pump and "coil" (not radiator) units in an LC system to cool the gear driven in-runner Neumotor in my Great Planes P6E Hawk.
Since the install is in a airplane that can be flow at negative Gs, I used two in tandem, so if one of the inertia pumps ingests an air bubble the other will push it through to the reservoir/ air trap I have installed.
The cooling performs with great alacrity. With the pumps on, maximum motor temperature is ambient 15F. With the pumps turned off, the motor temperature increases at a continuous rate about 30F/minute.
There are some concerns with reliability. The pump wires gauge is very conservative, so I soldered on regular servo extension wires and secured them to the motor bodies with HST. Also, since the pumps are driven by coreless motors, the MTBF is somewhat limited. Whilst these motors can be easily replaced with other off the shelf units, brushless motor powered pumps are far more desirable. After all, changing a motor pump involves draining and recharging the cooling system.

Cheers!

This great little unit. It doesn't exactly what it says it does. I cannot believe the amount of water volume that this little tiny pump circulates. However, it is unrepairable if a lead should come off the motor. At $37 US you'd expect to be able to repair this pump. My unit was damaged right out of the box unfortunately, I didn't notice it until I had installed it in my boat. The leads that go to the motor are so tiny that any amount of movement or vibration will cause it to break. The motor has no soldering tabs on it so the leads go into the motor. Once they break the unit is useless. There is no way of repairing it. They need to redesign it with soldering tabs on the motor so different leads can be used. This is my only negative thing about this product.

Unfortunately, after a bit of time working enters the water into the engine causing property damage and no longer works, the fan and the motor should be magnetically coupled, the radiator should be fitted with holes to attach a fan, the object is not yet perfected look patiently for this to happen. Thank you

System arrived with one broken wire on the water pump motor (impossible to solder). To avoid sending back the system (if you ever tried this you know why I didn't do it ;=)) I bought a fitting replacement motor in my local hobby shop. After that issue was solved I tried to insert water in the system. Till today I was not able to remove all air blister in the system. I am very happy for every hint.
