1. Locate fuselage and remove the covering from the throttle servo mounting hole, the wing slot, the
rudder and elevator servo mounting holes and the elevator slot using a sharp #11 blade.

2. Locate the landing gear components including 4 screws, 8 washers, and 6 nylon insert locknuts.
Assemble the axle/wheel assembly first. Place a washer onto the axle screw, then insert the axle
into the aluminum landing gear from the rear side. Place another washer onto the front side of the
aluminum gear followed by a nylon insert locknut. Tighten securely. Place a wheel onto the axle
screw followed by another nylon insert locknut. Tighten until the nut is flush with the wheel, but does
not cause binding.

3. Center the landing gear between the lightening holes just below the leading edge of the wing
slot. The bend in the gear should be even with the bottom of the fuselage. If you are using a light­weight engine you may want to angle the gear slightly forward to help achieve proper CG. Mark the
location of the two mounting holes and drill for the mounting screws. Use a washer on each side of
the landing gear and secure with the 2 nylon insert locking nuts.

4. Locate tailwheel components including tailwheel wire, tailwheel, wheel collar, and plywood trian­gle. File a flat area onto the wire where the wheel collar will reside. Place the tailwheel onto the
wire, then the wheel collar. Use thread lock compound on the retaining screw and tighten onto the
flat area. Use a #11 blade to open the slot in the rear bottom of the fuselage. Use a toothpick or
small piece of wire to apply 30 minute epoxy into the slot. Coat the portion of the wire that will go
into the slot as well as the plywood triangle with 30 minute epoxy. Insert the wire into the slot, fol­lowed by the plywood triangle. Use a piece of tape to secure the assembly while it dries.

5. Insert the horizontal stabilizer into the slot in the rear of the fuselage. Carefully measure to cen­ter the stab in the slot, and measure from a fixed point on the fuselage to the tips of the stab to
ensure proper alignment. Also use a square to to ensure that the stab is perfectly square with the
fuselage. Trim the slot as needed to achieve proper alignment. Make several positioning marks on
the stab with a fine tipped marker so that it will be easy to reposition the stab when gluing it in place.
Remove the stab and using a #11 blade, carefully remove a strip of covering from the stab to allow
for a wood to wood bond between the fuselage and stab. Glue the stab into the fuselage using CA
or epoxy. Use all of the criteria mentioned above to ensure that the stab is properly aligned to the
fuselage.
