Mr. Mugen -> YS110 tuning (4/30/2008 1:35:54 PM)

Anyone know approx. how many turns out the high speed needle is for the older ys110? Obviously not an exact number but a ballpark to get started? Never ran this one before but it has been broken in by someone else. The needles are all the way in right now.

Kevin



Flyboy Dave -> RE: YS110 tuning (4/30/2008 2:30:00 PM)

....I think it's one and one/half on both needles. [sm=teeth_smile.gif]



masama1107 -> RE: YS110 tuning (4/30/2008 4:57:25 PM)

Mr. Mugen,

I would start with 2 to 2 1/4 turns out on the main HS Needle valve, and start tunning from that point turning clockwise until reaching desired RPMs.

I have found this link very useful and I highly recommend it to everyone.

Good luck!!!



liquid_TR -> RE: YS110 tuning (4/30/2008 7:08:30 PM)

under average normal weather conditions I find the HSN to be less than 1.5 turns out on 110FZ. I would start with 2 turns out with the HSN then tune and regulator screw quarter turn in from flush position for midrange.



Mr. Mugen -> RE: YS110 tuning (4/30/2008 8:56:04 PM)

Thanks for the insight guy's! I fired it up a few minutes ago and ran it for a tank while tuning it. It is a power house! It transitions so smoothly I thought something was wrong........just the way a good motor runs I guess. I went from a saito 100 to this in my edge 540 and there is a big difference in transition. My pal and I are planning on flying tonight, he has the identical plane with the saito 100. We will get a side by side comparison tonight.

Thanks again,
Kevin



Mr. Mugen -> RE: YS110 tuning (5/1/2008 3:48:30 AM)

Another quick question for you guy's. I am using wildcat 15% fuel with 18% oil. Is this a god choice for this motor? I use it in all my others with good luck. Today it seemed like it wasn't getting to full top end. Maybe a weather thing due to the cold but just curious if the fuel might be the issue.

tadawson -> RE: YS110 tuning (5/1/2008 5:07:42 AM)

If I am not mistaken, YS specifies a MINIMUM of 20% oil, all synthetic, for all their engines. So, based on that, your fuel is *not* correct, and is underlubricating the engine.

Flyboy Dave -> RE: YS110 tuning (5/1/2008 6:13:15 AM)

....this is the YS engine recommendation....

....you can run straight castor in the YS if you so desire. [sm=wink_smile.gif]

The synyhetic only oil in the YS engine is an Internet myth.

liquid_TR -> RE: YS110 tuning (5/1/2008 9:10:38 AM)

Non-DZ models of YS engines could be run with small amount of castor oil,
but there is no need for it as all internal parts are lubricated with fresh charge of fuel, unlike an OS, Saito or clones.

DZ models of YS engines are NOT recommended to be run with any castor in the mix.

Regulator silicon diaphram is very sensitive and may get stuck or clogged if the engine sits for a long time with castor left in it.

Its a known fact that YS engines respond to 20/20 fuels very well. But they can be run with 15% nitro as well, just not as impressive as 20/20.

18% oil is not "underlubricating" the engine, but 20% oil is better than 18%..



carlosponti -> RE: YS110 tuning (5/1/2008 7:36:03 PM)

castor is fine however you can absolutely not run and petroleum based lubricant in the engine. some people try using mystery marvel oil as an after run which is fine in every engine but YS. it will destroy the silicon seals. the castor thing is just not recommended because of its properties of build up and gumming the inside of an engine. over time that leads to problems with the engine.



Mr. Mugen -> RE: YS110 tuning (5/2/2008 1:49:55 AM)

So 20/20 cool power would be fine then I take it. I found 30/30 cool power but not with less oil. Comments?



tadawson -> RE: YS110 tuning (5/2/2008 5:37:05 AM)

I guess I have been flying YS Heli motors for too long . . . for those, the specification is 20 to 30 percent oil, no lower . . .

Flyboy Dave -> RE: YS110 tuning (5/2/2008 7:42:00 AM)

....I read at the Central Hobbies site, the manual for the 1.70 DZ engine
only calls for 2% castor to be used in the engine. That seems odd to me. [sm=50_50.gif]

FBD.



liquid_TR -> RE: YS110 tuning (5/2/2008 9:42:27 AM)

Dave, it says 20-24% synthetic oil only but if you use castor, no more than 2%.

This greatly has to do with the direct injection system that may get clogged or damaged from castor varnish i believe..

Also the exhaust valve, seat, and valve stem will get hard carbon coated.



liquid_TR -> RE: YS110 tuning (5/2/2008 9:46:12 AM)

Mr. Mugen,

"Cool Power Pro pattern 20/20" is a great choice for the YS 110FZ.

Cool Power 30/23 Heli Blend is also fantastic. (If one can afford it to buy all the time :( )



Bob Yeager -> RE: YS110 tuning (5/2/2008 2:03:46 PM)

There is some useful information here:

blw -> RE: YS110 tuning (5/2/2008 3:58:05 PM)

Discrepancies between the same manufacturer source and another for the same engine isn't new. Saito has published the same conflicting information too regarding using castor. It isn't fun to sort out when this happens. I agree with Dave about this being odd.



MOTORMAN37 -> RE: YS110 tuning (5/3/2008 3:14:36 AM)

Wild Cat also makes a YS 20/20 blend that works excellent too.[)]

Well I just ordered a case of the 20/20 so once thats gone............. I will try the 30% soon. I have a quart of it here.



Mr. Mugen -> RE: YS110 tuning (5/9/2008 3:13:27 AM)

Well I ran about 2 quarts of the 20/20 today through the ys and it loved it. I got great run time and tons of power. Smoother transitions and idles for sure. Glad I asked!


Thanks,
Kevin



David Bathe -> RE: YS110 tuning (5/9/2008 11:11:35 AM)


I've run only YS engine for many years... and only used 30% heli, period.
No Castor. No problems.



Mr. Mugen -> RE: YS110 tuning (5/9/2008 3:10:07 PM)

I would assume the YS-53 I just got in the mail will take the same fuel as it's older brother?



still4given -> RE: YS110 tuning (5/9/2008 6:06:48 PM)

I run Cool Power Heli in all of my YS 4 strokes and they all like it. I'm certain your 53 will be no exception.

Blessings, Terry
