Drive Operation; General - Reely 1:8 GP Buggy Ultra Sonic 4WD RtR Notice D'emploi

3rd initial break-in phase
For three more tank fillings the vehicle can now be run at a slow speed (max. 1/2 throttle).
A mix that is too lean causes overheating and engine seizure. For a long engine life you should prefer a slightly rich
carburettor setting and a fuel with a sufficient percentage of oil (min. 20%). 16%) is favoured.
Overall, the real driving time (engine run time) should be approximately 45 minutes. After this time, the engine should
be run-in. You know that the engine is run in when it can be cranked up in cold state without spark plug and without
noticeable resistance.
Now you can operate the engine with full power.

7. Drive operation

a) General information
Enrich the mix by adjusting the main nozzle needle again, but keep the setting as lean as possible so that the model
runs optimally.
Attention!
It is always extremely important not to make the mix too lean! Keep in mind that the engine lubrication of the
two-stroke engine is effected via the oil contained in the fuel. Too little oil in the air/fuel mix causes engine
overheating and piston seizure because of faulty lubrication.
During operation, a light white trail of smoke coming out of the exhaust pipe should always be visible. If not, stop the
engine immediately and enrich the mix.
Also make sure that sufficient air circulates around the cylinder head, in order to avoid overheating. If necessary,
effect a corresponding opening in the car body.
The optimal engine operating temperature is approx. 100 – 120°. Check the temperature with a drop of water on the
cooling head: If the water evaporates abruptly, the engine is too hot. With operating temperature, the water evaporates
in 3 – 4 seconds.
Make sure that the rechargeable batteries of transmitter and receiver are fully charged.
Check the range of the remote control transmitter and the function of the RC- System.
Always try to drive the model at high revolutions! Avoid brief, strong throttle bursts when you want to drive
slowly! Avoid frequent slow driving with slipping clutch!
Always drive with attached car body. Thus, you protect yourself against burns if you touch the engine and the
manifold by accident and you protect the installed parts from flying rocks.
Bear in mind that the operation of remote controlled vehicles has to be learned gradually. Start with simple
driving exercises, e.g. circular driving. Use pylons or racing disks to delimit a course of your choice.
Get used to the driving behaviour in curves. Practice steering when the model runs towards you!
