    So with working in the Baden, I want to replace the rudder arms and go geared or even sprocket and chain. What's the best or easiest way to make sure they are all level to each other? By that I mean so they dont sit at an angle to each other, so they are in full contact all the time.

    I don't know if this would be considered best and/or easiest but this is what I did for my Bayern:

    3DP mount for the gear assembly and then a another mount for the servo. The push pull rods pretty much made sure that the servo was at the right height but a little slop there wasn't as critical. I've seen other folks use a 3DP mount that holds both the servo and the rudder shafts with the chain drive. That way everything is level and very little slop.

    I mount the gear directly to a servo wheel or horn whenever possible. I use formed blocks to make strong rudder post's so getting good gear mesh is as simple as putting it all together with a slip of paper between the gears for clearance and using rubber bands epoxy the rudder post's in place at the same time on twin rudders.
