Use a high Octane unleaded fuel (98 Octane is ideal)
We suggest starting the break in process of the engine on a test stand; for approximately one
hour. This time should be used to get familiar with the engine. Do not run the engine at full throttle
for more than ten seconds during this test stand break in. The reason for this is that you are not
getting the normal cooling effect that you would if the engine was in a model that was flying.
Another method that can be used for break in would be to set the engine between 2000-2500 rpm
and let it run for 4 hours. After that the engine would basically be broken in. Note: For break-in a
smaller propeller is recommended.
Important:
Remember that when the engine running ever
person must stay behind the line of the rotating propeller; never to the side or the front!
After Initial Break In
•
Use high grade fully synthetic 2-stroke oil
•
Use the oil manufacturer's recommended gas to oil mixture
•
Use a high Octane unleaded fuel (98 Octane is recommended)
•
We use 3W 2-stroke oil in our engines here in Germany, but there are other high grade
2-stroke oils that will perform well. The list below shows some 2-stroke oils that our customers
from abroad have used with success.
Pennzoil at 50-1
Redline at 40-1
Amsoil DOMINATOR Racing Oil at 50-1
Amsoil Saber 100:1 Pre-Mix Oil at 100-1
Note: The engine needs 12-20 hours running time for the break in process to be 100% complete.
