Hi all,
I´m new here at runryder,and have had a long break from
helis.Now I own a titan(+a old superio 90)but when I got
my ys the manual was in chinese!!!
My question is: which needle is for what and do they effect
each other in any way?
The titan is std exept for alufan/carbonblades and is beeing fed
with 20®rosawe/20nitro.
So far it had 5tanks,but running hot
Cant tell rotorspeed,but it feels good and +10-9 and doesnt bog.
I´d appreciate all help I can get!

Btw sorry for my lousy english!

Regards JP in Sweden

Low speed : 1 turn from fully closed. This is the screw on the right of the fuel inlet.
High speed: 1 and a half turn from fully close. I hope it is obvious where it is.

This is the starting point.

Distance to checkvalve should be 35mm from the backplate. The line on the checkvalve should be facing the fuel tank.

Hope this helps.

Thank you for that info!!
But my lowspeed needle was 2 turns open
ok it ran smoothly with plenty of power
but still too hot in my opinion.
Main needle was 1,5 turns open.
Forgot to mention that I´m running tt´s
stock muffler.
And yes the fueltubing from backplate
to checkvalve is 35mm.
Enya 3 is fitted.

I dont find the post but I am pretty sure I read here at RR that the back plate touch method does not work with the YS50. You need a temperature tool for this.

I was out testing today,set the needles to factory settings by
the manual(thx Andy).
Idle/hoverneedle 1 turn out/main 1,5= way too lean
No way I can get it to run (cool)
I´m not happy with this, so any ideas???
Ewerything is new so I thought that YS doesn´t
like TT´s muffler.and I´ll get my second YS hopefully next week so
I hope not to have to abuse next one as much as nr1.
Do anyone fly an R50 T equipped with YS50ST and std rappy muffler?
Or:which muffler should I buy for a happy YS?

I ran about 1/8 of a turn in from the factory settings on the idle, and about 1 or 2 clicks in on the main, and get a temp of about 195 to 200 Farenheit, (90 to 93 C or so), transition great, and lots of power. Muffler is a Revolution 50 size. Do you get pressure in the tank at the end of you flights? You might want to check the fuel system for leaks and/or check valve direction if not, since that would cause you to go lean . . . Oh, and temps were taken with a Venom on-board temp monitor on the back of the cylinder, 3 fins down from the head . . . and were peak of flights with full power climbouts . . .

Tim,
Yep my tubing is tight,are your ys running great at ewery rpm
with the Revolution 50?
My ys has now 6 tanks of 20®rosave/20% nitro but a friend of
mine also agreed to my theory that the ys don´t like TT´s
std titan muffler.

Early on I had a slight stumble through the midrange on spoolup, but leaning the idle a tad cleared that. So now, yes, I would say it runs nicely everywhere. I had a TT50 on my old OS, and the Revo is larger volume, so I think the YS likes it better . . . .

You say your tubing is tight - I take it you get a noticeable "whoosh" when you vent the tank at the end of a flight when you release the pressure?

Try setting the main needle first. If 1.5 turns is too lean, then open the main needle. You will then have to lean the low end. If opening the main needle does not richen the mixture, look for blockage somewhere in the fuel lines, filter, or carb. I am running 1.75 turns on main needle and 3/4 on low end if that helps. Maybe not maximum power setting, but it is plenty for me, and I'm looking for longevity. Byron's 30% Heli fuel, MP5 pipe, TRex 600 Nitro.

Rick

Tim,
Yes I get a strong whoosh ewen if I dont disconnect the fuel line immeadiatly,so I think it´s pretty tight.
Rick,
I´ll will absolutely try out your needle settings, but I see that you dont use tt´s std muffler either.

OK, then you have pressure and it holds, so the fuel/pressure system is working correctly . . . . . Do you have a more accurate way of checking temp than a finger on the backplate? If it sounds like it is running well, and you have good smoke, you may well be . . . . Other than that, from what you describe, the only other thing that comes to mind is a faulty regulator . . .

Doug,
I began to believe that was the case about the TT muffler.
MP5 is to be fitted next.

I've got an Hatori 521 fitted to the YS50 in my Airskipper and it runs as smooth as silk. It's a good combo and I've got no complaints.
