Hey Chris,
what is the difference for brushed and brushless? the site only lists seperate numbers, so I ordered one of each!

BUT... is it from TTech or not ?

Yes, it is designed by Richard, but i don't think T.Tech are responsible for the manufacture of it per se, but it is certainly a T.Tech creation.

me and my friend ( he's a touring girl) were discussing the thing on MSN, and we were thinking about "why cool THAT side of the motor?"
the part that creates the most heat are the brushes! They need to be cooled the most...

they do indeed create the most heat, but heat will dissipate along the can, so removing the heat from one end will allow heat from the "other" end to travel along the can, if you see what I mean.
I know it doesn't actually "travel" but the theory remains the same.
Have you seen the graphs on the website? They appear to prove that the TCS system is indeed working, and the motor is seemingly more powerful throughout the run.
the proof is in the pudding, and my pudding is in the first batch, so i will let you know when it arrives! ;D

I really think its rather useless, just like coop said. You really need to cool the area where the comm meets the brushes and at the moment the fan, i think does a much better job. Whats the point of sticking the cooling system of a real car round the exhaust system when you need to cool off the area where the heat is being generated, which is ofcourse. THE ENGINE!!  By the time the cann is getting cooled, meanwhile the TCS does little in saving your fried comm, perhaps if the motor fan and a seperate fan for the radiator could be put into use, maybe it'll make it far more effective?  |

Thermal Conductivity (a little data at the end of 12 months research & development) Heat in an electric R/C race motor is generated by current flowing in the com windings. This heat is conducted through the bearings and brushes and the air inside into the end bell and can. Because all of the major components in a R/C race motor are extremely conductive of heat, you can remove heat from any part of the motor and it will and does cool the whole motor. Because the motor is small dense and thermally conductive. We discovered this through our many tests and experiments on the bench and on the track using temperature sensors and telemetry to send and record data whilst the car was racing. The motor mounting face of the motor provides an ideal and practical area for the cooling plate, providing great thermal contact to the motor and hence very effective cooling. The graphs on the website were recorded by temperature sensors and sent to a lap top through on board telemetry. Those particular tests were recorder at Barham using an Xray T2 and CheckPoint 8 double and the results are typical of what you can expect. Richard Weatherley TCS

Im not all too convinced  Doesnt the motor plate even with its tiny holes more or less restricts the air flow?. Also would it be better off to cool around the can of the motor? afterall it is where there is most heat, surface to area contact?. Im not knocking off the TCS and i think its great idea making some cooling system. I think perhaps having some sort of really cooled air (like ac) blown directly into the motor can via side vents and onto the comm would do a much better job? ;D |

So anybody any thoughts on how to mount it in the preds? Radiator placement could be most interesting perhaps?
Looks a superb piece of kit!

it can't be all bad LRP are advertising it [ftp]http://www.rc-car-net.at/[/ftp] it was mounted to the X10 test car, on the outside of the chassis, on the left hand side at the front. Apparently, this is the best place for it, as it protected from debris & knocks etc, and it is one of the best places for airflow around the front of the car. lets see it hit the 4wd off-road and touring car market in a big way now  |

I'm sorry I can't picture it, so, If it's not too much trouble can you clarify. I would have thought inside the body would be a safer place from debris, wouldn't it? (space permitting). |

no problem at all....
the radiator but was mounted on the outside of the chassis, on the "forward" area of the tub. It was basically opposite the steering link but forward enough to be almost level with the inside face of the wheel - right by the steering rack, I presume. I do not know how it was attached, I can only presume there are mounting holes that enabled it to be screwed onto the chassis.
apparently, in this position it's not in an area that it can be hit by stones/whatever the tyre throws up, even on full steering.
from Richard "...On our X10 we mounted the radiator on the outside of the shell opposite the steering control rod (left side of car). It is protected there, it does not get plastered with dirt from the front wheel and yet it is a really good airstream. ..."
I hope that explains it a little better, if not let me know and I will try again.

Just got the message from Ian that it's available on the ttech page. Very cool system, who would of thought one day we would have thermal cooling in our RC cars. Techno keeps pushing further and further. For any trekers out there we can finally say "Coolant leak!" The inside of cars will soon look very complicated, just that third wire with brushless was enough now coolant hoses.. I will definitely wait for some reviews before investing... The other issue is moving it from one car to another seems like a lot of work, buying 3 of these is out of the question. Maybe they should invent some quick release system option. |
