Fast Electric RC Cars - How to optimum motor performance

Running your electric RC Car while your motor overheated could weaken motor spring, magnet and could burning your motor brushes. It also reducing your car operating time and may result you will be stop at the half way of the race. To avoid this happen, there are three methods to prevent your motor from overheated during it operate at high speed.
1.Proper gear ratio (pinion and spur).
2.Proper gap between pinion and spur.
3.Proper maintenance.

Basic guide.
1.Use proper gear ratio.
The best way to reduce or minimize your motor from heat is by using difference gear ratio for each circuit lay out. Although you had made a proper gear ratio setting for one circuit, it’s not meant that this setting is suitable for other circuit. To do this you are advised to follow gear ratio setting recommended by your electric RC Car manufacturer and by your own experiment.

Experiment Tips.
-Make an experiment to as many combination of your pinion and spur (ratio).
-Check and write down your result on all of your experiment until you get a suitable combination of your pinion and spur.
a) Acceleration during starting.
b) Maximum speed
c) Your laps time.
d) How your car acceleration after taking corner.
-Make an experiment with difference pinion first then by spur since replace pinion is easier than replace spur. At first you are advise to start your experiment of your electric RC Car with standard gear ratio recommended by RC Car manufacturer.
-Run your RC Car as you were racing and make sure your driving style and your electric RC Car run time is same when doing experiment.
-Stop and check your motor temperature by thermometer on every single ratio experiment. Don’t ever use your finger tip or drop of water to measure your motor temperature, it won’t give you exact result.

Setting Tips.
-If your motor temperature is too high, you should replace with a lower number of teeth of pinion.
-If your motor still cool, you should try to run with a higher number of teeth of pinion.
-During your experiment to find the best gear ratio, you should target to optimum performance.
-Less number of teeth of pinion will increase acceleration torque but less in top speed.
-More number of teeth pinion will increase top speed but less in acceleration torque.

2.Proper gap setting between pinion and spur.
Proper combination of your pinion and spur won’t benefit you if you are not concerned on your pinion and spur gap setting. This is one of important things
to consider to ensure your RC Car motor serve you at optimum performance.
Toward to this make sure your gap setting is not to close ( tight ), as it will cause your motor temperature increase faster and if your setting is too big it will cause your spur wear off faster.

Setting tips.
-Easy way to make an adjustment is by using a sheet of paper (A4 -60gm~70gm of thickness).
-Loose your motor mounting screw, put the paper in between of pinion and spur, turn your pinion until the paper fit between pinion and spur.
-Tighten the motor mounting screw.

3.Proper maintenance.
In order to make sure your RC Car motor continuously serve you better, you are advise to do periodical cleaning and lubricant on your rc motor. Use only “Cleaner and lubricant” recommended by RC Car manufacturer.
