Bruce88123 is correct readjust your servo arm on the servo to get a bit
more cable movement.. With the arm pointing almost stright back, I would
think you are losing some forward travel... That may just be enough??
Looking at your travel end points.. That looks to be enough movement,
That's more than I use on my 4*60-Mag 91 4c... Are you sure your cable
guide is not "flexing" somewhere?? I had the same problem on my 4* and
had to support the guide and it's worked great since...
