Mount The Engine - GREAT PLANES Ryan STA Instruction Manual

4. Use curved-tip scissors or a hobby knife to carefully
trim the molded fin and stab fairings. Note that the longer
fairing is the one for the fin. Trim the fairings as necessary
for a good fit, then carefully glue them to the fuse using thin
CA sparingly.
5. Join the rudder to the fin and the elevators to the stab
with the hinges. The same way you did the ailerons, use thin
CA to glue in the hinges. Connect the rudder cables to the
rudder and connect the elevator pushrods to the elevators.

Mount the Engine

1. Use four 8-32 x 1-1/4" SHCS, #8 lock washers and #8
flat washers to mount the Great Planes 60-120 Adjustable
Engine Mount to the firewall, simultaneously adjusting the
mount to fit your engine. Be certain the mount is centered on
the vertical line on the firewall. Tighten the screws and make
certain they do not contact the fuel tank. If they do, move the
tank slightly aft, or add additional washers to the screws.
2. Mount the back plate of the spinner to the engine.
Position the engine on the mount, so the back plate will be
5-7/8" from the firewall. This will provide the correct
clearance between the spinner and the cowl. Temporarily
hold the engine to the mount with clamps. Use a Great
Planes Dead Center ™

of the holes for mounting the engine to the engine mount.
3. Drill #29 (or 9/64") holes through the engine mount at
the marks you made, then tap 8-32 threads into the holes.
Mount the engine to the mount with four 8-32 x 1" SHCS
screws and #8 lock washers.
Refer to this photo while hooking up the throttle.
4. Mount the throttle servo in the servo tray the same way
you mounted the rudder and elevator servos (drill 1/16"
holes, harden the holes with thin CA).
5. Place a brass Quick Connector body on the carb arm
of your engine and secure it with a nylon retainer. Drill a
3/16" hole through the firewall in alignment with the Quick
Connector. Cut the remainder of the tail wheel guide tube
you saved to the correct length for the throttle pushrod guide
tube. Use coarse sandpaper to roughen the tube so glue will
adhere. Guide the tube through the hole you drilled in the
firewall for the throttle and glue it to the firewall.
