I recently installed a TT roll servo per Dynon install instructions:
https://www.dynonavionics.com/includes/guides/RV6_Roll_Kit_Instructions_Rev_F.pdf

Page 7 shows my install.


What befuddles me is that the servo control arm darn-near travels 180 degrees, causing over-centering. If it over-centers to the left, I make small push rod adjustments to fix it but then it will over-center to the right!

What am I missing!!!??? I was particular in following the above instructions - or so I think....

Thank you!

First, you used a Dynon manual for installing a different manufacturers servo; Generally best to use the manual that matches the product. Move the heim joint to a hole closer to the pivot on the servo arm. That will reduce the arm travel
