<DIV><SPAN class=724564713-03082004>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.</SPAN></DIV>

<DIV>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.</DIV>

<DIV>I have been running at 6,000 MSL and using a 14X10. Seems to
be a little light on prop. Any prop suggestions?
