| Thank you Pinecone,
I was not trying to be derogative.
Engine tuning, especially on helicopters has a lot to do with sound. A very experienced person can help you with the direction on where to go with your needles.

That would be my approach. Close the needles a tiny bit a the time until you get a nice steady note from the exhaust. Check the temperature while the engine is idling in between adjustments.
Things to remember:
Do not run plank 15% fuel on the engine, not enough oil.
If you switch fuel brands, be ready for a possible big change in needles, different oils make the engines act/tune differently.
Obviously 15% nitro will make less power than the 30%, as others wrote the needles are normally leaner, but stick with going always from rich to lean.
If you notice the engine loads up (blurbs) when you transition from, idle to mid, or from mid to high, but it clears out eventually, AND you cant turn the needles any leaner without overheating the engine, then try a hotter plug, like an OS A3 or an Enya #3, assuming that you are using an OS 8.
As for being called a dick, maybe I earned that for not giving a straight helpful answer. I still recommend highly to seek the help of an engine guru, but in the absence of one, keep at it, keep asking the questions here, and before you know it, you will be helping others.
Good Luck
