Your engine will peak faster and rev higher. That should reduce the potential for the head to bog during aggressive pitch transitions, making your heli more forgiving in the case of poor collective management. If your engine is bogging, it most likely a tuning issue.
Give that 21T pinion a go, I think you'll see a noticeable improvement. It should work well on the ST. Let us know how it goes.

I use exclusively Cool Power 30% High Performance Heli in all engines.
For a smooth running F3C mix I recommend a mix of Cool Power heli fuels.
SG Multi Viscosity mix:
For years I have been running in F3C competition this blend of Cool Power fuels to produce the desired results of power and ultra smooth running required for F3C competition. Many other pilots are now using this mix successfully.
1:1 mix ratio:
CP30% High Performance (pink color)
- 24% Low Viscosity synthetic oil package
CP12.5% Heli Fuel (purple color)
- 18% High Viscosity synthetic oil package
Alternate: CP 15% Heli Fuel (green)
-18% High Viscosity synthetic oil package
Mix in a 2US Gallon container or larger. 1US Gal of CP30% with CP12.5%. Shake lightly and let settle. Pour back into 1 Gal jugs if required.
The thin oil acts as a coolant and high flow lubricant. The thicker oil aids bearing life, and coats parts actually making the engine slightly quieter by reducing piston skirt slap.The end result yeilds about 21% Nitro content and 21% multi-viscosity Oil.

1st off, that idle-up1 curve is wrong. You're using the governor so why limit it at 90%? The governor won't be able to open full throttle if it ever needs it. Reset idleup1 and idleup2 to 100-80-100 and just program different headspeeds in the governor lcd.
|1. on low needle is 1 turn did u find it lean|
2. my muffler is outage 50 those this effect on tuning
3. Mixture arm do i need to rich a bit before i install
4. at the moment without this mixture i recorded it reach 115 at peak teamp, do i need to lean or rich abit before i put in the mixture to my needle
i read 1 of ur post at runnig this engine at 1.5 open will fry the engine (weather in brunei all year round summer at 32-35 celcius.
how about ur low needle setting coz at this moment most of my fren says that my 1 turn in low needle is lean
About the rest...
1. low needle is on mine just flush (slot is inline) with the carb. Not sure how many turns however that doesn't matter. Start the engine. Let it warm up for 30 seconds. Now pinch (or even unhook) the fuel line.
a) it dies imediately - lean
b) it starts reving up for like 3-8 seconds and dies - ok
c) it takes like 20 seconds to rev up and die - too rich.
What you want is b) and you shouldn't care if the screw is at 1 turn or 10 turn. What matters is what makes the engine happy.
2- Every pipe will slightly affect tuning. A hatori 521 might give other settings than a MP5 SB or an Outrage. Which one is the best... you need to do experiences or trust what other people say. I had very good results with the 522 and 521. Never tried a Outrage pipe.
3 and 4- no, just set middle point to be your present needle setting. Adjust your MGP mixture control to 115C or a little less (110-112).
Mine is at 116C and max temp in flight is 118C. This is with high quality 20% nitro (maybe equivalent to normal 25%. I would guess 110-115 is ideal for you. 115-120C is healthy for my standarts. More than that and engine life will start to be reduced.

Check Valve For 1 way pressure to the tank form the crank case
Review of engine:
This is my new experiance in YS engine,

-low needle at 1.5 turn
2nd tank break in close 3 click from 2 turn high needle temp at 140 farenhite
then 3 tank close another 3 click making it 1.75 turn out
thank now close anther 2 click from 1.75 turn low needle close 0.25 making it 1.25 turn out
temperature at this settting is at 170 farenhite
Glow Plug Use is OS8 as recomended from manual for 30% nitro
Nitro is Morgan Fuel - cool power 30% nitro LS 20% oil
soo far break in for 4 tanks gonna finish and change the plug after 12 tanks
and settle tune at 1.5 turn on high needle anda 1 turn on low needle as most ppl recomend on the forum plus this engine get more power at rich side of tuning..
