Note: The engine speed will increase by about 10–30% during flight. This is because the engine is moving and more air is being sucked into the carburettor at a higher pressure, which enriches the mixture. In addition, as the fuel level in the tank drops, it becomes more difficult for the engine to draw fuel, especially during aerobatics, which further enriches the mixture. It is therefore necessary to set the mixture slightly richer on the ground to compensate for this leaning of the mixture in flight. Always monitor the exhaust gases during flight. The engine must always leave a visible trail of white smoke. If you do not see smoke, the mixture is too lean. You should land immediately and set a richer mixture.)
LUBRICATION
When the engine is properly set, the fuel provides plenty of lubrication while the engine is running. After the last run of the day, the engine should be run dry of fuel and an after run engine oil should be applied to the engine‘s internal parts through the carburettor and glow plug openings. This will protect the engine‘s moving parts from rust and other deterioration.
