largescale cars. Most normal 1/5 scale kill switches, plug straight in place of the stock button provided.

necessary to operate the vehicle in a suitable, controlled environment. It should not be operated
in a public space where people are engaged in other activities, such as a public park. Do not operate
in an area where there are children playing, near pets or other animals. Do not operate on a public.

Loss of control of such a vehicle could result in serious injury to another person, family pet or other
animal.
Be aware that the engine silencing is minimal so do not run the engine in an area where this could
cause a nuisance. You and those around you should always use ear protection during operation.
Please note: All of the manufacturers safety instructions for the operation of the vehicle in which the
engine is fitted, must be followed.
Fuel Safety Guidelines
Fuel is highly flammable. Never operate the vehicle near open flames. Do not smoke while
handling fuel. Always operate the vehicle in a well ventilated area. Model car engines produce
