O.S. .91 SX-H C-Spec Ringed w/Pump - Inflight Control Needle

[siwind]

I just pick up a new Cspec PS for my raptor and after reading that some of the engines had problems running lean at idle and mid throttle, I would like to know if anyone had tried using an In-Flight needle Control Valve on an aux channel ?

Shannon Davis does on all his machines and I used to have one on my Extreme. On the top end needle. It is not needed on the idle needle, you will be setting that about as rich as you can. You can put it on one of your Variable knobs of your TX. Works great but adds a little weight to your copter.
Here is a photo.

Thank you for the photos, Iwill try that set up.
I already use a In-Flight needle Control on my Raptor 50 hyper.
