Fast electric rc cars - Painting the body shell.

When you painting your fast electric rc car body shell by your self, at the same time the design and color that you has choose are represent of your creativity, patience and talent. Remember the more color you had selected to used, the more difficulty you will face on doing this work.

There are two ways to paint your fast electric rc car body shell :

1.Masking tape - This is ready made masking tape and can be find at rc cars hobby shop. You can choose from various design and suit for your fast electric rc car body shell.

2.Own design - You can make it difference by your own identity, creativity and design. Normally painting fast electric rc cars body shell look more beautiful and professional when you make your own design, even it will take your times and more effort but you deserve to get a pride of your time and effort.

There are a few steps to follow to painting your rc car body shell.

1.Prepared all tools you will need.
Dish soap, Clean cloth or paper towel, High quality masking tape (3M), Permanent marker, Straight and curved scissors, Sharp hobby knife, Body reamer , Pencil, Compatible paint, Window masks, screw driver.

2.Cut off body wing.
Normally your body came with a wing or spoiler molded into the excess material, you must cut it off. Some wings are molded in the opposite direction of the body. If this is the case you must remove the protective film, and paint the reverse side.

3.Marking your body post.
Mark your mounting body before you paint. Drop the body over your chassis, center it and use a permanent marker to mark the body posts. You can also mark the wheel wells. Touring car bodies sometimes have no rear wheel well outlines, this give you freedom to make a perfect fit for your chassis. A great tip is to make a wheel well template, and use it to trace 4 wheel well shapes. They can be made from either scrap of your molded body or cardboard.

4.Wash your body shell.
After all the handling and cutting, wash the body ( Inner surface ) to remove all chips, dirty and oily from your hand. Wash the body and wing sets with dish soap and water and pay attention to the tight curved and corners areas. Dry it thoroughly with clean cloth or towel. Make sure your body completely dry before the painting process.

5.Painting your body.
-Apply the window masks to the inside the body. The masks keep the windows clear while you paint.
-Apply masking tape for the design you would like for your body.
-Apply spray on your body surface evenly and wait until the paint completely dry.
-Peel off masking tape.

Tips.
-If you would like your body design look beautiful, normally it can be more than 2 or 3 color. The masking tape can be design by your own or you can choose to buy from hobby shop. Keep in mind that the more color you will use the more difficulty for you in doing this process.
-When painting, you usually work from the darker to the lighter color to avoid the subsequent coat from showing through.

6.Trim and Mount the body.
Trim out your body using curved scissors for the wheel wells and straight scissors for the lower lines. Use the body shell reamer to make the body post and body wing holes, remember not to make that hole too large.

7.Remove protective film and window masks.
After all work has finish remove the protective film, and the window masks.The protective film will help keep your body from getting scratched during your work.

8.Finishing.
Apply or stick all cosmetic sticker included with the body.

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.
