YS110 Props

[Dan Borg]

Have you called YS Performance on this?  Give Rich or Dave a call it sounds
like the piston needs to be gas ported, but I would think that being a 110
it is already done.  Have you taken the engine apart and looked for any
foreign objects?  In the past I have found material from the machining
processes in the regulator on my YS engines.  

 I would say that your 14 X 10 is a little light maybe a 15 X 10 or 16 x 8.


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?
