Mount The Servos - GREAT PLANES Ryan STA-M Instruction Manual

18. Holding the fin fairing in position, use a fine-point
ballpoint pen to draw a line around the fairing onto the
covering. Remove the fairing and poke several pin holes just
inside the lines.
19. Use a tissue dampened with denatured alcohol to
wipe away the ink line, then position the fairing and carefully
glue it into position with thin CA. Refrain from using CA
activator. If activator must be used, apply small drops with a
T-pin or a small wire.
20. Cut and fit, then glue the stab fairings into position the
same way. Note that the stab fairings go around the trailing
edge of the stab.

Mount the Servos

Before the servo trays can be mounted, the blind nuts for
the engine mount and the fuel tank must first be installed.
1. If using the included Great Planes adjustable .60 - 1.20
engine mount, cut out or photocopy the engine mount bolt
pattern template provided on the back cover of this manual.
Use spray adhesive or tape to hold the template to the
firewall aligning the lines on the template with the lines on
the firewall (if necessary, extend the lines on the firewall with
a straightedge and a pen). Mark the center of the holes on
the firewall through the template with a sharpened piece of
wire or something similar. Remove the template, then drill
7/32" [5.6mm] holes through the firewall at the marks.
2. Install the 8-32 blind nuts in the back of the firewall
using an 8-32 x 1-1/4" [32mm] socket head cap screw and
#8 washers to pull the blind nuts all the way in.
3. Assemble the fuel tank. Arrange the stopper and tubes
as shown in the photo, then fit them into in the tank.Tighten the
screw to expand the stopper, thus sealing the tank. Be certain
the fuel line weight (clunk) at the end of the fuel line inside the
tank does not contact the rear of the tank. Otherwise, the line
may become stuck during flight and discontinue fuel flow.
Remember (or use a felt-tip pen to mark) which tube is the fuel
pick-up tube and which tube is the vent (that will be connected
to the pressure fitting on the engine muffler).
