Engine Care and Maintenance

After 25 hours of use, the engine needs to be returned to the factory for maintenance. The

main tasks are replacement of bearings, inspection of parts, cleaning of oil lines,

replacement of internal filter elements, removal of carbon deposits, re-balancing, re-

commissioning, ECU data reset. When returning to factory for maintenance, include the

entire electronic system with the engine.

In case of crash damage, return the engine to the factory for repair.

When removing the engine or the fuel pump, it is necessary to connect the fuel nozzle with a

small section of tubing and close the fuel pipe to avoid any impurity entering the engine or

the fuel pump. If even a very small impurity enters the engine it may cause the fuel line to

block up or make the pump gear failure, or a flameout.

On any new installation, you must carefully clean the fuel tank, fuel pump outlet must be

installed oil filter, make sure the fuel lines are clear of any dust or metal particles.

Ensure the power connection to the ECU is not reversed. If any electrical plug is found to be

bad, replace immediately - intermittent power supply is also likely to cause ECU failure.

Engine cooling after the flight directly affects the life of the bearing, allow the engine to

complete its cool down sequence after every flight before removing power.

The keys to affect the life of the turbojet: overheating, heavy fall, ultra-extreme use. After

any accidental flameout, run the cooling manually - set trim low and throttle high to run the

starter motor.

If the engine suffers a heavy fall, return engine to the factory to re-balance. If any foreign

body is sucked in, resulting in blade damage, it is recommended to return to the factory to

re-balance, otherwise the bearing life will be seriously shortened.

Regularly check and clean the fuel filter.

After starting the engine, push the throttle to maximum to check for any air bubbles, as these

can cause a flameout in flight.

The engine should not expel any flames during startup. In the case that the fuel solenoid

valves become damaged or worn (eg by grit in the fuel) then fuel may pool in the engine

while refueling and cause a fire on startup.

Always close the manual ball valve in the fuel line when refueling, to avoid this possibility.

Do not attempt to start the engine if it becomes flooded with fuel, as this will cause a fire.
