VMA-E240X Easy 3D 40-52 & Electric ARF - Aileron Horn Hole Location
Question: We have a VMAR Easy 3D and find that when we install the aileron servos and the aileron control horns they don't quite line up and the control rod ends up not quite perpendicular to the hinge line. Can we move the control horn slightly?
Answer: Yes. Simply redrill the control horn bolt holes so that your aileron control horn aligns better with your aileron servo arm. Depending on your servo arm length and the orientation of your servo you may wish to redrill the new horn bolt hole slightly inboard or slightly outboard of its original location.
 
To fill in the original hole use Epoxy or a short length of wood dowel.
