screw and screw part way down into the blind

nut.

21. ‡ Install the MOTOR MOUNT BOTTOM and both

MOTOR MOUNT SIDES to the fuse,as shown.

Use a generous amount of glue, as this is a high

FIREWALL GUSSETS in place. They should be

located 1/4” back from the edge of the motor

mount, as shown.

23. ‡ With the blind nuts to the inside and the V-notch

on top, epoxy the FIREWALL into the fuse. Use

plenty of epoxy and let dry thoroughly.

upright position.

through the bottom of the wing.

‡

Remove the wing from the fuselage and, using

the pilot hole as a guide,

19. ‡ Test bolt the wing to the fuse and, following the

procedure used before, again check the align-

ment by making sure the dimensions from wing

tip to tail are still equal on each side of the

model.

‡

Being careful not to get glue on the dowel, glue

the WING DOWEL SCAB PLATE over the wing

dowel and to the front side of Former B2.

‡

Glue the LANDING GEAR COVER PLATE in

position.

‡

Make sure the holes are aligned. Then, taking

wing bolt pad and glue to the wing.

NOTE: Brush On™ Super Jet is excellent for this job.
