ZYX Pitch confusion
I was setting my pitch to -10 -- +10 for maiden on my 450SEv2 with a dx8 TX.
I had to back way down to 34% __ 37% to get -10 -- +10 on the travel in pitch servo setup. I use the Software with usb interface for programming. Is this Normal or am I missing something?

I have an almost identical setup to you with hitec hb 65's
I have the dx8 set at or about 100% each way for throws and about 11 degs each way on the pitch, collective pitch creen is set to 60% on the zyx and this give reasonable climb out. My first guess is that you have the ball to far out on the servo arm, or if you have a positional ball on your blade grip, then can this be moved further out to reduce the throws? |

I'm redoing everything, and have found like you did that using the collective pitch variables on the pitch screen limits the pitch range while setting the dx8 at 100%. The only problem now is I'm at about -17 +5 so think I may need to raise the swash some

When you go through your setup from the beginning, clear your pitch range in your tx to give a 0 25 50 75 100 line. Make sure you have everything centered on the setup screen. Use subtrim and atv & reverse/normal to get the sliders moving the same way as the sticks, make sure you see a 0 when you centre the stick and 100% when you push to the limits.
Then when you are setting up the head put your stick to mid stick setting 50% and then go to the monitor screen and confirm it is 50% or pretty near. Set your swash to give you equal throw up and down. Then check you have a level swash, adjust on the screen using the buttons,if its miles out use your links once this is right put your head back on and set the grip links to give 0 at mid stick, this should get you somewhere near the correct settings, Then use the screens to give you your desired throws, and collective range. Thats what i did with mine and it flies great, |

Thanks that is exactly what I did and I only had to adjust 1 link to the head 1 turn to get it all sorted out. Won't be able to maiden until this weekend if the weather is good but everything is in order now.

I had the exact same problem. With the program set a 34% when I tried to lift of I couldn't hover until almost full stick. I have the same servo's to. I raised it to 65 and it takes off a couple of notches above half stick. What do you mean by adjusting only 1 link? When i'm at 50% stick my washout arms are parallel with each other and to the main shaft.
