Default New Brushless Cooling - TCS

This is the new "Brushless Cooling System" from TCS

New Brushless Cooling - TCS-dsc00484.jpg
The new cooling plate fits onto the speedo.
Various plates are available for different speedos. This one is for Novak GTB, LRP Sphere, and Nosram

The results are amazing. In recent testing the following data was relayed by Spektrum Telemetry

Borden (UK) test - Brushless Motor.pdf
Borden (UK) test - Brushless ESC.pdf

The track and gearing was deliberately chosen to push our brushless motor and speedo to the limit. At 5minutes 20 seconds, the Motor and ESC without the TCS went into thermal cut out mode.

As you can see, once the TCS was fitted, the temperatures came right down and we even had the option to fit more power !

What was the running weight of the chassis?

A Complete TCS weighs 48g (approx 1.8oz)

The figures in the graphs are from a Predator, at off-road weight of 1590g.

The results from a touring car at 1500g are pretty much the same, but using a more powerful motor, a 4.5 instead of 6.5, to obtain similar temperatures.

Was temperature data taken after the car was stopped? I am trying to figure out why the end of the temp graphs dip back lower around 330 sec. Is this when the car was taken off the track?

Yes the car was stopped at 5 minutes

The running temperature was taken every 30 seconds.
We used telemetry to obtain the data, so that the car could be run continuously for the whole run, without stopping it.

The telemetry enables you get real time information without affecting the results by having to stop the car and take temperatures.

Yes, there is a liquid cooled plate that goes between the motor and the mount, and a second cooling plate that goes on top of the speedo.

(please see images above)

correct me if I am wrong, but the liquid is for cooling. This is achieved by cirulating the liquid from the motor/ esc plate to the radiator by a small pump.

Default TCS

A tiny micropump circulates a non-conductive liquid through the system. The fluid passes through a thin plate which is sandwiched between your motor and chassis where your motor's excess heat is extracted into the coolant. Forced by the pump the coolant continues to the cooling radiator which efficiently releases all of the excess heat, into the passing airstream.

On the Brushless TCS there is also a cooling plate which attaches to the speedo.

A typical TCS installation contains just 5ml of coolant (about a teaspoon). It is highly thermally conductive, but NOT electrically conductive.

The radiator is also very strong, you could throw it at the wall and it won't break.
Two different installations in a Tamiya :-
