Great Planes Giant Aeromaster Kit - GPMA0502 - Manual (Page 30)

D 24. Draw a line on the landing gear plate 1-1/2" from the
aft edge of former (C). Then draw a centerline from front to
rear. Position the aluminum landing gear so that the
square edge is aligned with the centerline and the 1-1/2"
line is centered in the middle hole. Mark each hole location
and drill a 5/32" hole through the landing gear plate at
each mark.
D 25. Install six 6-32 blind nuts from inside the fuselage.
Use 6-32 x 5/8" socket head bolts and #6 flat washers
inserted through the landing gear and threaded into the
blind nuts. Tighten the bolts to seat the blind nuts in the
holes. Add a few drops of thin CA around each blind nut to
secure it.
D 27. Place the tank floor in position. From the 1/4" x 1/4" x
16" hardwood stick, cut a gusset to fit in the joint between
the tank floor and the firewall. Use 6-minute epoxy to glue
the tank floor and the gusset in the fuselage.
D 28. Fit the top deck in position. From the 1/4" x 1/4" x 16"
hardwood stick, cut gussets to fit in the joints, on the top and
bottom, between the top deck and the firewall. Use 30-minute
epoxy to glue the top deck and gussets in position.
D 29. Drill a 3/16" hole through the firewall and former (B)
at the mark for the throttle pushrod exit. Use 150-grit
sandpaper to roughen up the 36" outer tubing. Insert the
outer tubing through the firewall and slide it up to former
(E). Trim the tubing flush with the firewall. Drill two 5/16"
fuel line exit holes through the firewall aligned with the fuel
inlet on the carburetor.
D 26. Use medium CA to glue the 3/8" x 2-9/16" x 4" balsa
blocks to the bottom front of the fuselage between the
firewall and the landing gear plate. From a 1/4" x 1/4" x 16"
hardwood stick, epoxy two gussets inside the fuselage at
the joint between the bottom front blocks and former (B)
and between the bottom front blocks and the firewall. After
the epoxy cures sand the front of the blocks flush with the
fuselage sides.
D 1. Use thin CA to glue the die-cut 1/8" plywood formers
(N), (P) and (Q) in position perpendicular to the top
rear plate.
