❏ 27. Glue the shaped 7/8" thick balsa Elevator

Root Blocks to the elevators then use a razor

plane and a sanding block to shape them as you

did the tips.

❏ 28. Draw centerlines on the leading edge of the

elevators and on the trailing edge of the stabilizer.

Mark the position of the hinges on the elevators

and stabilizer using the locations on the plans as

a guide.

❏ 29. Cut the hinge slots now and temporarily

install the hinges. Refer to the detailed hinging

instructions on page 48. NOTE: Do not glue the

hinges yet, but wait instead until after the

model is covered.

❏ 30. Sand the elevator LE’s to a “V” shape to

allow for the elevator travel (see the stab cross

section on the fuse plans).

❏ 31. Hold the bent 1/8" Elevator Joiner Wire up

to the elevators and mark the location of the holes

(see the plans). Remove the elevators from the

stabilizer and drill 1/8" holes in the elevators to

accomodate the joiner wire.

❏ 32. Make slots inboard of the holes to allow the

wire to be inserted into the elevators. Hint: A piece

of 1/8" brass tube sharpened at one end makes a

great gouge for cleanly removing material from the

leading edge of the elevators. Trial fit the stabilizer

to the elevators with the joiner inserted and confirm

that the elevators align with each other. Make

adjustments if required.

❏ 33. Mark the location for the 1/8" x 7/8" x 1"

plywood Elevator Horn Block on the bottom of the

right elevator. Remove material as needed to allow

the horn block to fit flush with the surface of

the elevator.

❏ 34. Glue the elevator horn block to the elevator,

then sand it so the pieces blend together.

BUILD THE FIN AND RUDDER

The Fin and Rudder are built simultaneously just

the same as the stabilizer.

❏ 1. Remove the die-cut 3/32" balsa ribs V-1

through V-5 and R-1 and the die-cut 1/8" balsa Fin

TE’s and Rudder LE. Be sure to preserve the

jig tabs.

❏ 2. Cut the fin leading edge to the exact length

shown on the plans from a piece of 1/4" x 11-7/8"

tapered balsa stabilizer LE stock. Notice that the fin

LE fits into a notch on top of F-9.

❏ 3. Slightly bevel the front edge of the ribs to

match the angle of the leading edge stock.

DRAWING CONTROL SURFACE CENTERLINES

1. Accurately measure the center point at the two

extreme ends of the surface to be marked.

2. Insert a T-pin at each of the marks.

3. Hold a straightedge against the pins, then draw

the centerline.
