YS110 Props

[Bob]

Bruce:
 
I had the identical problem with a brand new YS110.  I called Tony at Radio
South and he suggested that there must be an air leak somewhere and
recommended that I send the engine to YS Performance since it was a new.
Although I have not run the engine since it was returned to me from YS
Performance, the note on the packing slip said "tightened loose screws and
completed test run".  Evidently Tony was right.  Loose screws can cause air
leaks and the resulting surging.  Hope this helps.

I have a new YS110 that has had a surging problem since new.  We have tried
the YS idle setup and that didn't work.  You will start it and within about
20 seconds, it will surge and then load up (it appears) and die.  Cool power
25 and heli 30, OS F plug.  I can get to run long enough to get airborne and
then it will die on base or final when in the landing pattern.  But it stays
lit on stall turns and other maneuvers where it is reduced to idle.
 
I have been running at 6,000 MSL and using a 14X10.  Seems to be a little
light on prop.  Any prop suggestions?
