Install the wheels onto the axles and secure with the wheel collars, as shown.

Slide one wheel/axle assembly into a wheel pant, and install the wheel assembly on the landing gear leg.
Tighten the locknut as shown to secure the assembly onto the gear leg. Repeat for other side.

Attach the gear to the fuselage with short 3mm screws, use loctite. Install gear cover plate as shown. We have used clear
tape in this photo, but thick CA or epoxy glue works well.

Measure back 2.25” from the hinge line on the bottom of the rudder. This is where we will install the
tiller guide for the tailwheel. Make a hole in this location (using a 1/16” drill bit or the end of one of
the wire pushrods in your kit) and glue the tailwheel tiller guide as shown with medium or thick CA.

Install tail wheel as shown. Use two wood screws to secure bracket to fuselage. Remove the set
screws in the tailwheel assembly, apply loctite and re-tighten.

Remove a square or two of covering on the bottom of the fuselage behind the wing as shown, for
cooling.

Remove covering as shown from horizontal stabilizer opening and rudder pull-pull wire slot.
Remove covering from the elevator servo opening on the left side of the fuselage as shown.
