Test Pilot
Don't run props under a 15-6 on this engine. They are ported for big props and if they are underproped will lean out in the air. Keep them under 10,000 on the ground. 15-6 to 15-8 props are perfect for this engine. Will be trying APC 16-4 wide balde this weekend as i am using this plane on a funtana x50 3d.
With Kangke s tech staff s words; (For SK 50) Keep max RPM about 11000-11500 on ground.(Means choose prop accordingly).Otherwise overporting will occur and some unwanted results.
