Ok, back in bussines, the eye is doing good, vision is excellent, but not 100% yet, the right eye at least
With sirrom's help ( aka Patrick ) I was able to complete the final steps of programming the independent trims on all the control surfaces using a Flight mode mix, I'm still scratching my head as to how F modes works, that's a subject for another build.
I will prepared the KC to take to the field tomorrow to do some checks there, no flying, even if I could, that's an honor for my friend, the owner.
Will report tomorrow night.
