Wings will be setup with two different configurations,
precision and 3D. For the precision setup two servos will be
used one is mounted inboard and second servo outboard
of the wing. Middle servo bay will be left unused. This is
the configuration as the wings come out of the box. For 3D
setup, all 3 servos will be installed and middle servo control
horns need to be glued in. Follow the below steps.
Precision Wing Setup
1. Prepare the aileron servos by installing the rubber
grommets and brass eyelets.
Hint
: Prepare all servos for the wing at this time.
2. Secure a 36-inch servo extension to the outboard
aileron servo lead using string or a commercially available
connector. This will prevent the extension from accidentally
disconnecting inside the wing.
3. In order to harden the servo mounting holes in
the bays, mount the servo screws, back them out and
apply some thin CA in the hole. Wait until CA is dry before
installing the servo. Do this for every bay that a servo is to
be installed in.
4. A string has been installed in the wing to pull the
aileron servo extension through the wing. Tie or tape the
string to the end of the extension and pull the lead to the
wing root.
5. Mount the servo such that the output shaft faces the
leading edge and prepare the linkage for installation.
