Switch on the radio system and confirm that all controls work correctly and are in the

correct direction. Ensure that you have the throttle cut switch set to fully close the throttle

and stop the engine. After setting up, reconfirm that the throttle works by testing whether

it stops the engine.

Switch on the ignition and close the choke. Then, flip the propeller until the engine fires or

runs for a few seconds.

Release the choke, then set the throttle at a little higher around idle position(be aware that

the engine can start on any flip of the propeller at anytime, even if the ignition is off). Give

the engine a quick flip. It normally takes 5 to 10 flips to start the engine.

After the engine starts running, slowly open the throttle to a low idle and allow the engine

to warm for 30 seconds. Then progressively open the throttle to full power and hold for 5

seconds to confirm that the engine can maintain full power. Next, throttle back and set the

idle to a low RPM.

WE STRONGLY RECOMMEND THAT YOU FOLLOW THIS PROCEDURE TO

START YOUR ENGINE.

We recommend breaking in the engine on the plane. Do not break it in on a test stand, even if

you have a test stand with a proper cooling system, because doing so may cause the engine to

overheat. We consider the engine fully broken in after 25 liters of fuel. The break-in procedure

is as follows:

1. Start the engine at idle for 2-3 minutes (lower than 2500 RPM)

2. Slowly push the throttle to around 4000-4500 RPM and run a tank of fuel. Then stop the

engine and let it cool down.

3. Restart the engine at idle for one minute. Then slowly push the engine to full throttle. Do

not stay in full throttle for more than 5 seconds. Make sure the needle setting is done/ right

and the engine is running smoothly.

4. Stop the engine again and let it cool down, before putting the cowling on and letting the

plane fly. The engine should run smoothly from the beginning and improve as flight hours

accumulate. We consider the engine fully broken in after 25 liters of fuel.

◎ Make sure you have a proper cooling system on your plane before flying.

◎ Do not run at full throttle than 10 seconds before the engine has been broken-in.
