28. Remove the covering over the hole in the rear of the fuselage for the elevator servo.
We recommend the MKS 1220 metal gear digital servo for elevator actuation. Attach a
24" extension to the servo lead and install the servo with the output shaft toward the rear
of the fuselage using the manufacturer supplied mounting hardware. Thread a ball link
on each end of the metal pushrod and secure to the servo arm and elevator control horns
with a 3mm bolt and nylon insert locknut. We recommend the Extreme Flight 1.5 inch
servo arm for elevator actuation. Be sure to use a drop of blue Loctite on all bolts!!!
29. The canopy is retained by 2 spring loaded hatch latch mechanisms. There are also
plywood tabs with blind nuts installed and we recommend using these with 3mm bolts to
retain the canopy in addition to the latches when using a gas engine.
30. Included in your Extra kit is a set of side force generators (SFGs). These aerodynamic
devices add to the effective side area of the aircraft making knife edge flight and other
maneuvers that depend on rudder authority easier and more stable. The SFGs also tend
to make the aircraft more stable in high angle of attack maneuvers (harriers). I highly
recommend that you install them on your aircraft and experiment. They are secured to
each wingtip with 2 3mm thumb screws.
