Thanks Bob,

I'll try that.

After I started my engine today I was making some adjustments in the Tx while my engine was sitting idling for at least two minutes. I didn't notice if the RPM was increasing or not, but it seemed to be running fine, but I'll try your test tomorrow. Interestingly, the idle always seems to increase from where it was when I first start the engine to a higher rpm after the engine has warmed (after a flight). I always have to bring down the throttle trim several clicks to bring down the idle rpm when it's time to come in for a landingthus, indicating it may be a little lean (as you suggested).
