The servo arms visually appear to be 90 deg to the servo cases when adjusting the swash to level in step 7 of the wizard. I'm using the cable-tie around the main shaft approach to make this measurement as I don't have an official swash leveler tool for this Gaui X3. The swash appears to be very level after this was completed.
The work bench is very close to perfectly flat according to a bubble level I have used for heli setups before. I have a RC Logger type digital pitch gauge and when I put this on the tail boom or motor can top or the CF frame pieces near the motor, in both directions I'm within 1 degree of 0. I use the zeroing button on the gauge before checking angles at that point.
Personally, I like to set the collective pitch first Step 9 of the wizard. With the DX9 pitch curve set to 0, 50, 50,50, 100 to ensure level with at mid-stick I check both blades during this process and needed to pop off the ball links and turn in half-turns to adjust both blades to reach this to 0 degrees at mid-stick. I have only basic linkage rods - not left and right threaded type infinitely adjustable rods. I was able to get to within sub 0.2 degrees of level on both blades at mid-stick. I then check max/min aiming for 12 deg of collective range and I can get within about 0.3 degrees +/- on each blade at max/min collective. All seems good so far.
I then return to step 8 for the 6 deg setup and with the RC Logger again set to zero on the motor can / CF frame, and the blade towards the back - I adjust to -6 degrees. This is where when rotating the head around to blade forward I'm way off from 6 degrees.
I will double check this again and make sure the 50 PC values on the DX9 are showing 0 value on the Spirit setup tool. I will also check my other heli's that are setup with a Spirit and flying to confirm they show 6 deg both forward and back on Step 8.
Thanks for your input and thoughts.
