i. Care and Maintenance
Failure to follow break-in procedure and/or damage caused by 
improper tuning will void your engine warranty.
There are two ways to “temp” your engine. One, purchase a 
temperature gauge. The second cheaper, but less accurate method 
is the “Spit Test”. Wipe a little bit of saliva on the engine head and it 
should burn off in 3 - 4 seconds (the boiling point of water normally is 
100 °C). If it evaporates immediately, chances are the engine is running 
too hot.
The engine will run best and be easier to restart if run around 
100-125 °C. Depending on your weather conditions, air density, and 
humidity, your carburettor settings will be changing wherever you 
decide to run. Making adjustments in small increments is the best way 
to make sure your engine lasts a long time. Overheating is caused by 
running the engine too lean, or too much stress on the engine created 
by the environment. Extreme overheating will result in internal failure 
of engine parts. 
There are many online resources that will help you with engine tuning. 
3,5 ccm engines are designed to last a long time, and with proper 
maintance and tuning, you can drive the model for hours at a time.
After Use
When you have finished running your car, there are two options to 
shut the engine down. The first method is to place your thumb over 
the exhaust outlet (Wear gloves). Make sure your engine is normal idle, 
preferable with the brake activated. 
The second method is to pinch off the air supply from the engine. 
Do not pinch the fuel line, as this may cause the engine to overheat! 
Try and let all the remaining fuel run through the engine, emptying 
the fuel tank. The engine will idle high while the tank is emptied, so 
the above two steps may not be necessary.
Then apply after-run oil through the carburettor, and pull the pull-start 
a few times to get it through the engine. This is recommended if you 
plan on storing the car for more than a day. Methanol evaporates in 
water and can cause internal corrosion to engine parts. It is always a 
good idea to check all the screws, nuts, and bolts before and after each 
period of racing. 
Keeping the car clean will also make it more fun to work on. This can 
be achieved with a large heavy-duty paintbrush, or compressed air. 
Always test the transmitter and receiver batteries before starting the 
engine.
Racer Tip:
Wear gloves when working on your hot car!
