2. If powering your PT-19 with a brushless motor, cut the
covering from the air exit vents in the bottom of the fuselage.
For a better fi nish, cut the covering about 1/32" [1mm] inside
the edges of each opening and use a trim iron with a rounded
tip to seal the covering neatly down around the edges.

3. Cut and remove the balsa spacer from the back of the
fuselage under the fi n fi llet.

4. Mount the wing to the fuselage with two 10-24 x 2"
[50mm] nylon wing bolts (for convenience, you may shorten
the wing bolts by cutting off up to 5/8" [15mm]).

5. Test-fi t the CA hinge and the tail gear into the rudder.
❏
6. Test fi t stab and fi n (with CA hinge and tail gear) into the
fuselage. View the model from behind. Check the alignment
of the stab to the wing—if necessary, you can use tape to
hold the elevators level and even with the stab.
❏
7. If necessary, adjust the slot in the fuselage to get the
stab horizontally aligned with the wing—in most cases, all
that will be required is a small amount of weight on the high
side of the stab. The stab saddle can also be sanded slightly
to get the stab to align.
❏
8. Remove the stab and fi n from the fuselage. Leave the
CA hinge in the rudder, but take out the tail gear.

denatured alcohol handy.
