Scale Radiator Cooling System

Liquid cooled electric RC cars. Sounds all steampunky, but it's real. My TB01 used to run really hot. I bet this system would help that chassis out a lot. None of my current cars run that hot but I can always gear up! I am put off a bit by the price. Part of me is thinking that I could piece something like this together for less money using boat stuff and some ingenuity. I also think this needs a small reservoir to maintain consistent temps. I remember being at the dyno and watching the temps rise on a friend's air to water intercooler because his reservoir was too small. There's probably some thermodynamic equation that we can use to calculate the required volume of liquid to keep this system cool but I'm not going to bore you with my genius. Instead I'm going to dazzle you with TCS's info about their cooling kit.

New Thermal Cooling System Lifts The Ceiling On R/C Performance!
An amazing liquid cooling system for electric R/C car racing:

• MORE POWER
• MORE RELIABILITY
• LESS MAINTENANCE

Down With Heat!

Over the last few years battery technology really moved forwards and provided R/C car racing with reliable cells with great performance. The low internal resistance and high capacity of today's batteries has cured the longstanding problems of lack lustre performance and poor duration. But it has brought us a new and irritating problem, HEAT!

Heat is the enemy of high performance electric motors causing constant rebuilds and higher internal resistance which slows Modified and Stock Racing motors alike.

The new Multi Patented TCS has been meticulously developed over the last 12 months to address the "Heat problem" and promises new levels of performance and reliability which can be fitted to your existing car.

With possible changes to racing regulations in mind The TCS has been developed using 4 and 5 cell configurations too, with equally stunning results.

There are two main versions of the TCS:

• TCS-BL :For brushless motors and speedos eliminating bulky heatsinks and fans
• TCS-BS : For 2006 & 2007 brushed systems. Modified, Restricted & Stock

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.

You save money too, because overheating destroys your motor magnets, brushes and commutator, meaning constant rebuilding and sometimes blown motors and speedos.

EFFICIENT? - oh yes!

The specially developed TCS pump uses less than 0.5 watt, whereas a typical twin fan setup uses over 2.5 watts.

The TCS Thermal Cooling System

has been developed in conjunction with the world's leading manufacturers.

Background Data:

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 your motor are extremely conductive of heat, you can remove heat from any part of the motor and it will cool the whole motor. 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 actually racing.

The motor mounting face 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.

The figures shown in the graph were recorded at the Barham track in the UK, using an Xray T2 and CheckPoint 8 double and the results are typical of what you can expect with a TCS fitted.

Traxxas XL 2.5 with a 540 Sized Motor

I have been curious about the little Traxxas XL-2.5 esc. I have two in my Redcat RS10 and they're amazing. My only complaints are the brakes are weak and the lack of a switch. Since I had a good experience with it in that vehicle, I wondered how one would work in a car. I could not find any clue to its amp rating so I had no idea what it could take. Because of that I decided to put one in my M02 with a Mabuchi silvervan.

2.4 LCD 3ch Radio For Less Than $50 and an Italian Prototype

China makes some cool stuff. I know 90% of the time you see the word Chinese online its usually followed by the word crap. Maybe those were the people who bought the $50 iphones or something. I have had great experiences with them (Except my headlight buckets, going on week 3 and still waiting) and I order something from China nearly once a week. Their wheels tires and headlight kits are good. The bodies aren't bad either. I've been e-stalking these radios for a while now in hopes that I would find out if they are any good. Well I have read so many positive reviews that I decided to bring them to you, here, now.

I have also been dreaming up plans for a modular chassis. Something that can be configured different ways for different builds. I'm stuck right now because the guys at the CNC shop won't accept my designs because they are on napkins, and a receipt, and a voice recording. The guy said he needed them to be in CAD. So I slapped his momma. I can be a cad when needed. Needless to say I'm banned from that machine shop.

When you see the word sexy you think of Eva Mendes right? Wrong, every word in the English language should remind you of Eva Mendes, even fart. This little machine here is pretty sexy too. It's Italian and it's also being advertised as modular. They are still a very long way out on it but they have release pictures of it. It's from a company called KTuning. Supposedly you can transform it from a 1/10 scale car to a robot an 1/8 scale car. Well just like Eva Mendes, I don't care what it smells like I just like the way it looks.

Our modular chassis for 1:10 and 1:8 on-road class

The division of the chassis in three distinct parts, allows you to do any setup changes without redesigning a new model. This solution permit us to do all modify, setup and draw hopup not changing all the car but simply dedicate us to the single component. You can choose the features of the model, Category, Motorization, Components, as you like and buy only the components you want. Nothing could be easier to not redesign complete models and have many models with one chassis! The electric power is growing, be ready without buying new models you can choose which motor mount, fuel or electric is your free choice.

Do you have just buyed another model? We can help you reusing the components you have! dampers, pulleys, belts, bearings, we can help you to get the model you want at the lowest cost you prefer.

Control the cost: you can start with the base configuration and buy in a second time the component you want to make other class models. You can start with the Classic chassis (the cheaper version), then, after few times, buy (for example) the damper system and deciding if you want to use the traditional system or the innovative push rod system. With the same ease you can buy the component you want to change car type every time you want for example from a 1:8 prototype to a F1 and so on.

The chassis can be naked with a treatment of polishing or anodizing on customer color request.

The complete chassis will be available from next November.

Speed Passion 1/8th on-road Brushless Conversion

You want one of those ballistic 1/8th scale on-road cars but you're afraid of gas engines. Yeah I know, not everyone can have the over abundant testosterone that I have. Now you can have your cake and eat it too. The brushless conversion for the Serpent 960 by Speed Passion is the answer to your wet dreams. Actually I don't see why this is a brushless conversion. It looks like you can use any 540 based electric motor. I am also willing to bet you can rig this up to work with nearly any 1/8th scale on road. Look at the pics and read what the manufacturer says:

One Way Adapter for Serpent 960

Idea Stealing Number 1

Ok I saw this little doo-hickey on a Japanese site. I thought, "I should make these for my charging setup." The idea is to have alligator clips on your charger and a few of these adapters for the batteries.




You should be able to figure it out from the pic. I'm going to make them for Tamiya, Deans, and Anderson plugs since my batteries have all three.
