YS-91 AC Inverted
I am working on a new plane design that has me thinking of using my YS-91 inverted. This is the first 4-stroke I have had but I have frustrations in the past using 2-strokes inverted. Am I in for the same here or are things improved using a 4-dtroke inverted? Thanks in advance.

RE: YS-91 AC Inverted
you should have no trouble with the inverted YS 91 AC Have 100's of Pattern flights with the 91 ac inverted. I have gone back to running the fuel lines out side the model. it is nice to pinch the line . Great flying motor

RE: YS-91 AC Inverted
Hi,
Your success with the YS-91ac is admirable,all the more so in light of my lack of success with this powerful little screamer. To date, I have reset the tappet clearances and replaced all gaskets. I cannot seem to achieve a balanced high end with a steady low end. I use PowerMaster YS fuel and am running with an APC 14X6 prop and follow the engine instructions. Do you reset the regulator adjustment? Suggestions would be very appreciated!
Best Wishes,
Jim
