I have pulled some helis out of hiding and need some help making sure the needles are set in a good starting point...all to be run on Cool Power 30. Helis are Ergo, Vigor CS, Rappy 60

Engines are:
YS 80
OS 91
OS 61 (3 needle version)

Any help would be great

I think ppl means that you should search for it

I looked around for YS80 settings yesterday and today, couldnt figure what flush with carb barrel body meant, but saw that 1.5turn was good for starters on low needle

Ricks has plans of the YS80 including the manual.
http://www.jkheli.com has a tips&tricks page there YS80 settings are mentioned.

The other engines I have no clue about

Good luck!

PS Erikson sounds really Swedish!?

well, in the first case, I think there would
be no shortage of information by
doing a search.

YS80:

L: flush (apprx 1 turn)
M: 1.25-1.5
H: 0.75

hey z11355

Can you explain that "flush" thing, how one can tell that its 1turn apprx?
Is it slang or what (im not sure that slang is the correct word Im looking for also )?

z11355,
I did a search on optimal running temps on the YS engines but got no clear answers, im looking for something more concrete than "if you put your fingers on it and it burns ya, then its lean" .....will you please answer the question....Whats the optimal operating temp of the YS61STII? Thanks

Guess who's back, back again...

honestly, I use numbers for the low
end. I wasn't hhappy w/ vague terms
like 'flush' either.

Most folks are in the 0.75-1 from fully
closed setting.

My foggy memory of the OS61 is
L: ??? whatever it needs
M: 0.25 or so, very insensitve
H: about 1

I have no f*g clue what the optimal
operating temp is. I don't tune my
engines like that. Although the nice
IR temp gauge I got as a gift amuses
my pets to no end

I tune until the engine sounds happy
and I'm not blowing plugs.

Oki I admit it I got to much spare time!
But wouldnt it be great if there was a sticky post in the engine and muffler forum, that contained needle settings, temps etc for all engines?? Easy for all to find, since its "sticky"?

Thanks, mine is set 1.5 since break in time, what a sound and response compared to my OS32 in my Caliber
The ground shivered

H: 0.9 With Muffled tuned pipe, 1.25 With Hatori pipe.

YS61StII
L: 0.5
M: 1.5
H: 0.75

Settings of course vary with ambient air temperature, barometric pressure, rel. humidity; as well as Nitro/Oil content & plug.

but every engine, fuel, plug, exhaust
and altitude combination is different
so it's an exercise in futility IMO
since no one will agree on any of it
and people will STILL refuse to
look it up

Hmm I guess your right...
But the settings from the manufacturere could be posted in it?
They should have som clue I hopes.

Oki I also admit that I bought my YS80 from non European country and received the engine with a japanese manual, can hardly tell which side is up or down

In regards to the low end needle, mine is one turn out exactly but is a lil recessed, not quite flush with the carb body (i was concerned about that in the begining but it seems happy)
I know that people that have been flying for awile tune there engines according to sound, smoke, and performance, but ive only been playing with R/C for 7 months now and am still unsure of my tuning abilities. So having a temp # at least says i can go a lil leaner without damaging the motor. My majior problem is in a rapid desent from way upstairs, when i apply abrupt power at the bottom it bogs, and in a stall turn it bogs at the bottom if I reduce collective to much and apply alot of collective at the bottom. This is teaching me collective management ie: not reducing collective so much, and applying collective a lil earlier and more steadily through a manuever. But I feel as though im compensating for an incorrectly tuned motor, and that is preventing me from pushing my comfort zone.
I know that the OS32 likes to operrate at bellow 200 f, and ive heard that the YS whants to be at under 220 f, just wondering if anyone knows......
p.s. i use enya #3 with the YS61STII, and C/P 30 is its food!

Guess who's back, back again...
