I went to the field yesterday to fly for a few hours due to bright, sunny skies and no wind. I cranked up the TT .46 pro and tuned the high end for the heat (~92 and humid). However, I did notice that when I first start the engine and remove the glow plug the idle goes down significantly. It doesn't die but goes down a fair amount (you can definitely hear it). I believe it's the low end needle tuned slightly off but I'm not sure exactly how to fix it. (turn the screw to adjust.... I know) but I'd rather ask and educate myself here than mess around for too long out there.

Thanks!

John
