It's necessary to take breaks during your runs to give the RC time to cool it’s motor.
Sometimes your laps or runs may be cut short from overheating from hot weather. Some RC car systems have good electronics that detect and prevent malfunction to your car. The car may auto cut off to protect it self. To improve your run times you may want to install a cooling fan on top of the motor. You have a couple of ways to use it. One is just after a drive so the motor cools down quicker or while driving but may still consume more power from the battery. I prefer after a run because the left over energy from the battery is still sufficient enough to run the cooling fan for five minutes or more. This can help bring down the motors temperature much faster and get it ready for your second battery.
The first thing you need to do is buy a few things.
1. One 30mm cooling fan.
2. One 30mm cooling fan cover.
3. Two 18cm screws. Make sure the diameter fits the holes.
4. Extension power cable if necessary. (may come with fan)
5. One LED 3 bulb if using a laminating cover.
I picked up a Wild Turbo brand 8.4v fan. Also an illuminating fan protector by Active Hobbies, they come in various colors. The illumination adds a bit of excitement to the look of the fan. Start by removing the four screws from the original motor cover. The part that says caution hot. Place the cover and screws in a safe place for future use. Place the fan and protector on top in it’s place. A couple things to be aware of is to check and see that the fan is blowing down. The other is to make sure the fan position properly so it will rotate. The magnets inside the motor could interfere with the fan’s rotation. When it is all set up the LED will run off the Tamiya light unit and the fan from the last slot on the receiver.
