Glow plugs wear out, especially in the run-in phase. Thus, we recommend you always have some glow plugs ready for replacement. Glow plugs have different

heat ratings. The type of plug chosen has a great influence on the vehicle's performance. In the run-in phase, you should use a "cold" glow plug for high-

performance engines. After the run-in phase, you can change to a glow plug with an average heat rating.

Only use glow plugs intended for RC! The wrong glow plug, e.g. one intended for 4-stroke flight engines, prevents the engine from running properly

and makes adjustments more difficult.

Our tip: Degrees of heat of glow plugs

• Standard glow plugs for fuel with added nitromethane (approx. 5%)

• Cold glow plugs for fuel with added nitromethane (approx. 10 %)

• Super cold glow plugs for fuel with added nitromethane (more than 10 %)

Inserting or replacing the glow plug

You need a glow plug wrench (wrench size 8, 9, 19, and 12).

Preheating the glow plug

A glow plug starter with rechargeable battery is put on the glow plug to heat it, causing the air-fuel mixture to ignite and the engine to start. The glow plug starter

is removed when the engine is running smoothly.

e) Tools and aids

The model is ready to run (RtR). Before the first start, some basic settings have to be made or checked and the required accessories and equipment have to be

ready.

Go through the individual points of the check list to make sure your model is ready.

Tools

• Wrench for the wheel nuts (7 mm)

• Flat spanner (5 mm and 5.5 mm) to set track and camber

• Allen key (1.5 mm) for the grub screws on the adjusting rings of the throttle/brake and steering linkages

• Philips head screwdriver

• Slotted screwdriver for the throttle stop screw and the main jet needle

Aids

• Cable ties

• Air filter oil

• After-run oil (special low-viscosity machine oil to lubricate and protect the combustion chamber from corrosive residues in the engine after operation)
