14. Use a rotary tool with a grinding bit or a small file to create a flat spot on the tailwheel
wire for the set screws in the aluminum fittings to seat against. Reassemble the unit and
apply Loctite to the threads on the setscrews and reinsert into the aluminum fittings and
tighten snug. Slide the tailwheel onto the wire and secure with the included wheel collar.
15. Position the tailwheel assembly on the rear bottom of the fuselage and be sure the
tailwheel wire is aligned with the rudder hinge line. Secure the tailwheel with a couple of
pieces of masking tape while you drill 2 holes with a 1/16” drill bit. Apply a few drops of
thin CA to the holes and allow to dry then secure the assembly to the bottom of the
fuselage as shown with the 2 provided coarse thread wood screws and 2 washers.
Fuselage Assembly
16. We’ll begin by installing the landing gear. Locate the aluminum main landing gear,
4 3mm bolts, lock nuts and washers. Insert the gear into the slot on the bottom of the
fuselage and center it in the slot. Secure the landing gear with 4 3mm bolts, washers and
nylon
insert lock nuts by inserting the bolts and washers into the pre-drilled holes in the
aluminum gear mounts inside the fuselage with a long T-handle wrench. Secure with the
3mm nylon insert lock nuts
