Setting up the throttle on the radio and doing the tuning on a new engine have always been a bit of a mystery to me. There seem to be a many subtle adjustments needed between radio and engine to get a really good high end and low engine setting. I basically always end up relying on somebody at the field to do the fine tuning.

So I'm wondering about what "step-by-step" procedures you all might have to do the initial setup and tuning of a newly installed engine? Below is roughtly my "procedure" (but there more guessing the thinking in this).

First, before I take the model to the field, I set up the radio/servo/throttle so that at the top of the throttle trim setting the carb opens full at the full stick position and just a crack open on the idle setting.

Now comes the hard part at the field:

1. Set the needle initially to about three turns open.
2. Set the stick at full throttle.
3. Start the engine.
4. Close down the needle until I get a good high end (with my Saito engine I take that to be in the 9500-10000 range)
5. Move the stick to half throttle.
6. Start adjusting the EPA on the throttle low end so that I get something about right on the idle end of the stick.

At this point I usually have an engine that runs well full open but dies so after I move the stick to idle.

7. Then I start "messing around" with the low throttle setting.
8. Get nowhere.
9. Look around for someone who knows what they are doing!

ALL ADVICE WELCOME!!!
