Join The Control Surfaces To The Fuse; Install The Stab - GREAT PLANES Ryan STA Instruction Manual

4. Reposition the axle onto the gear and tighten the
screw. Be certain that the screw has "landed" on the flat spot
and that the axle has remained parallel with the leading edge
of the wing. If not, remove the axle and adjust the flat spot as
necessary. Securely mount the axle to the landing gear with the
6-32 x 1/4" cap screw and a drop of threadlocker on the screw.
5. Fit of the right wheel pant over the gear. (The right
wheel pant is the one that fits the right wing best when fit over
the landing gear.) Slip a wheel collar followed by a 4" wheel
and another wheel collar onto the axle. Adjust the position of
the wheel collars until the wheel is centered in the opening in
the wheel pant. Temporarily tighten the outer wheel collar to
the axle with a 6-32 set screw.

Refer to this sketch for the following two steps.
6. With the wheel pant positioned on the wing so the
wheel is centered in the opening, drill 1/16" holes through
the wheel pant into the landing gear blocks where indicated
by the arrows in the sketch. Enlarge the holes in the wheel
pants only with a 3/32" drill, then mount the pants to the
wing with four #2 x 1/2" screws.
7. Drill 1/16" holes into the wing over the landing gear
rails for the landing gear straps. Secure the landing gear
to the wing with four nylon landing gear straps and eight
#2 x 1/2" screws.
and wheel collars has been determined, remove the wheel
pant and the wheel from the landing gear. File a flat spot on
the axle for the set screw in the wheel collar that holds on
the wheel. Reassemble all the parts using a drop of
threadlocker on the set screw in the wheel collar.
8. Return to step 1 and mount the left landing gear and
wheel pant to the wing the same way.
While working on the fuse, it helps to have a stand or a
cradle. We use a Robart Super Stand II (ROBP1402).
1. Trim the covering from the fuse over the slots for the
stab and fin and over the holes for the rudder control cables.

2. View the aft former through the slot for the rudder.
Check to see if there is a balsa hinge block glued to the
former for the bottom rudder hinge. If there isn't one, make
a 1/4" x 1/4" x 1-1/2" (or a similar size) hinge block from a
balsa stick and glue it into position as shown in the sketch.
3. Temporarily install the stab in the fuse. At the trailing
edge, measure the distance between the tips and the fuse.
Position the stab until both measurements are equal and the
trailing edge of the stab is centered.
