Top 80 Engine Break-In

Proper break-in will provide you with a better running engine, it will also provide for considerably longer engine life. During the break-in, gently change RPM from idle to 3/4-throttle and back.

The procedure from Miniplane is as follows:

1. Run the engine, varying the RPM, for 2 minutes.
2. Stop the engine and let it cool off for 2 minutes. Check for loose bolts, etc. during this time.
3. Run the engine, varying the RPM, for 5 minutes.
4. Stop the engine and let it cool off for 5 minutes. Check for loose bolts, etc. during this time.
5. Run the engine, varying the RPM, for 10 minutes.
6. Stop the engine and let it cool off for 5 minutes. Check for loose bolts, etc. during this time.
7. Continue 10 minutes of running, 5 minutes of cooling until 30 minutes of run time is achieved.

At this point, you can fly. However avoid long periods of full power, and vary the throttle setting often. For heavier pilots that require more power to fly, it is recommended that 1 hour of non- flying break-in be completed before flying.

Break-in is complete after 10 liters (2.6 gallons) of fuel have been run through the engine. Avoid using fuel that is mixed with oil that is more than two weeks old.
