RE: Dx6i
It's an Exceed Raptor G2 ( Walkera36). Head is not adjustable from what I've been told, and it's the stock all plastic head.
so just a basic set up I'm guessing. I've got the throttle/pitch curve set linner from low - high for now, unless you have a suggesdtion.
I may experiment with a steaper pitch curve once I'm sure it's running correctly. I just started basic slow forward flight and very basic turns, all VERY normal flight mode for now LOL
