kink the tube. Test fit the stopper into the fuel tank.
The seam around the tank should be horizontal
and the stopper hole on the left as you look at the
front of the tank. By holding the tank up to the light
you will be able to see where the vent tube is, in
relation to the top of the tank. If necessary, bend
the vent tube to position it about 1/8" below the top
of the tank. When satisfied with the fit, make sure
the stopper is fully seated in the fuel tank. Tighten
the stopper screw until the plastic cap is indented
about 1/16". Doing so will lock the stopper into
position. Check the clunk and pickup tube to make
sure they move freely in the tank without binding or
stopping.
3. Locate the foam fuel tank collar and remove
the center portion. Install the collar to the front of
the fuel tank.
4. Before installing the tank, make sure the bent
vent tube points toward the top of the fuselage.
Apply a bead of 100% silicone sealer around the
sides of the rubber stopper and the front edge of
the fuel tank. Insert the tank fully into the tank
compartment while working the stopper into the
hole in the firewall. The silicone will seal the
opening and help hold the tank in position after it
has cured.

1. Locate the 1/8" [3mm] plywood stabilizer
mounting base and test fit to the fuselage. Lightly
sand the base if necessary to obtain a good fit.
Remove the base from the fuselage. Reinstall the
base using a generous amount of 30-minute
epoxy. Be sure there is enough epoxy to properly
secure the base to the fuselage. Remove any
excess epoxy from the outside of the fuselage with
a paper towel and rubbing alcohol.
2. Draw a centerline on the top of the horizontal
stabilizer (stab) from the aft edge to the leading
edge. Center the stab on the stab saddle using the
centerline, and slide it forward until the leading
