1. Heatsinks are a simple and effective way to help keep motors running cool. Usually made of aluminum, there are several types depending on the specific application. On touring cars and other vehicles where the motor is well exposed, a finned heatsink can attach directly to the motor to help disburse heat. Since space can often be tight on 2WD off-road vehicles, a heatsink motor plate that is milled for more surface area will help accomplish this task.
2. Trying to squeeze the most speed out of a vehicle can often cause people to gradually increase the size of their pinion gear by one or two teeth or even more. Unfortunately, over-gearing a vehicle will result in the motor running hotter and hotter, causing it to run inefficiently and eventually, burn out. Likewise, under-gearing a vehicle to increase run time will also cause the motor and battery to run hotter. Ensuring that your vehicle is geared correctly will keep it operating efficiently and will help keep the motor and battery cool.
3. When the body is fully secured on a vehicle, it will often do a great job keeping dirt and debris out of the chassis area. Unfortunely, this also limits air flow to the electronics under the hood. Using a body reamer or Lexan scissors to cut a few well-placed holes in the body to increase airflow and help keep motors, speed controls and even batteries operating at cooler temperatures. Even better, some bodies already have areas designed to be cut out for just this reason. Read More »
