• Always use fresh fuel and keep the tank lid firmly shut. With time, model fuel absorbs humidity from the air. This
humidity reduces the performance of the fuel and leads to faulty motor performance as well as engine corrosion.
• Empty the tank if you do not use the model for several days. The volatile components of the fuel, nitromethane and
methanol, evaporate and leave an oil deposit, which enriches the fuel mix and may clog pipes.
• Once you stop driving the model for the day, unscrew the glow plug and drip a few drops of engine maintenance oil
("After Run", a low-viscosity machine oil) into the cylinder. Replace the glow plug and turn the model upside down a
couple of time so that the oil can spread in the combustion chamber. This prevents corrosion.
• In case of longer drive pauses, e.g. during the winter, put 2 – 3 drops of preservation oil (accessories) into the
cylinder.
• Fix fuel hoses on the connector nipples with thin cable binders or special hose binders (accessories). Otherwise the
oil in the fuel can cause slipping.
Air filter
The air filter prevents dirt from penetrating into the engine via the intake air. Foreign objects sucked in between the
cylinder liner and the piston cause piston jams, which destroy the engine and result in subsequent damage to the
power train.
• Clean the air filter with paraffin or low-viscosity machine oil (air filter oil, accessories).
• If you want to clean the air filter with a detergent and water, then rinse it thoroughly afterwards. Soap residues could
get into the engine and damage the lubricating film.
• Oil the air filter afterwards with air filter oil.
• Never drive without air filter!
• Fasten the air filter with a thin cable binder.
Driving at adverse atmospheric conditions and ambient conditions
The components of the RC system are not water-proof!
Close the receiver box carefully by not only snapping the lid into place but also by pushing the latch forward.
