Nonstop that is pretty good advice but it doesn't work for everybody.

Needle valve settings will very a ton depending fuel, temp, elevation and so on.

I was in Alb New Mexico a few weeks ago and my HS needle on the 170DZ (glow) was at 7/8ths and it was actually a bit too rich. Albuquerque is about 5000ft elevation.

I also ran the Focus Sport out there and it has the YS 110S on it. It ran about 1-1/8th open.

We were running 30% Cool Power Heli fuel. If a guy was only running 15% nitro the needle would need to be set even leaner yet. There are just way way too many variables.
If you travel to high elevations you will be amazed that you have to dial in the HS needle say 1/2 turn or more from Muncie to Denver. Not sure you conditions in TX...but try going to the Lubbock contest when Ed Deaver gets back on his feet. You will learn what tuning a engine at High elevation is like. I think Lubbock is about 4k to 5k.

So you can't use a blanket setting that is too lean. It just doesn't work. Peak it slowly a click or two at a time, and back it off 300rpm. This is the proper way to set the HS needle.
