and 40" [1016mm] of red air line to the aft fi tting on
the air cylinder. There is not enough air line left over
from the main gear, so additional line will have to be
purchased separately (Robart #169 Pressure Tubing).
❏
11. Place the tail gear (fi xed or retractable) in the
fuselage while simultaneously guiding the pull/pull cable
through the white plastic guide tubes. If installing the
retractable tail gear, also guide the air lines through
the fuselage.
❏
12. Drill four 3/32" [2.4mm] holes through the rails
for mounting the tail gear. If your drill bit is not long
enough to reach the rail nearest the top of the fuselage,
use medium CA to temporarily glue a 3/32" [2.4mm]
drill bit in a 1/8" [3.2mm] brass tube. After drilling the
holes, the drill bit can be removed from the tube by
heating the tube.
❏
13. Mount the tail gear in the fuselage with four
#6 × 1/2" [12.7mm] sheet metal screws. Enlarge the
center hole through the 1-3/4" [44mm] tailwheel with
a #9 [5mm] drill. Cut the axle included with the Robart
retractable tail gear to the correct length; then, fi le a
fl at spot on it and mount it to the strut.
❏
14. Locate the fi berglass tail gear cover. Place it
onto the fuselage making sure you align the color
markings on it to the markings on the fuselage. Drill
three 1/16" [1.6mm] holes into each side of the cover,
drilling through the fuselage. Secure the cover with
six #2 × 3/8" [9.5m] screws. It is recommended that
you harden these screw holes in the balsa fuselage
with thin CA to be assured the threads are strong.

Did You Know?… Did You Know?…
The P-40 Warhawk was a deadly fi ghting machine in
trained hands. The formidable armament of 6 × 12.7mm
(.50 caliber) machine guns (up to 200 rounds per gun)
was complemented by the ability of the aircraft to carry
a bombload for an increasingly expanding workload.

1. Cut two 4-40 × 48" [1220mm] metal pushrods to
a length of 30" [762mm]. Insert the pushrods into the
upper pushrod exit holes on each side of the fuselage
as shown in the photo.
❏
2. Thread a 4-40 nut, threaded clevis and a silicone
clevis retainer, 12 turns, onto both elevator pushrods.
