Again the decision to use landing gear retracts must be made before
construction begins Construction provisions have been built into
the model for retracts There is room in the center of the wing,
foreward of the main spars, for a servo (mechanical retracts) or a
servo and valve (pneumatic retracts) The air supply tank (pneum
system) is located in the fuselage Be sure the tank(s) and air lines
DO NOT INTERFERE with the pushrod operation The model
can be balanced with the wheels up or down as the fore and aft CG
remains the same
This plane is designed to have operating flaps if desired The flaps
will have to be hinged and control horn added, instead of fastened
solid as shown on plans Provisions have been made in the wing
for the additional servo The decision to have operating flaps must
be made before the wing construction is started
Drill 1 /4" dia x 1 3/4" deep hole in leading edge in center of
wing Install 1/4" DIA x 2" LONG DOWEL with epoxy
Dowel should stick out at least 1/4" Sand slight radius on
end of dowel
Epoxy face of F—21 (PLY) and slip over dowel with epoxy
away from wing Do not get epoxy on dowel Put the wing
with F—21 (PLY) in place on the fuselage and align carefully
Temporarily fasten it down This will correctly locate the
F-2KPLY) on the fuselage
When the epoxy has set and while the wing is still fastened
down, drill two 1/8" DIA holes thru wing and thru fuselage
blocks See plans for location dimensions
Glue F-10C to wing only(not to fuselage) Glue F—9C on
wing See plan for location Make two cross pieces from scrap
1/8" stock Sheet over this area with 1/8" soft sheeting
Remove wing Tap fuselage holes with #8-32 self tapping
screw furnished Drill wing holes out to 11/64" DIA for
screw clearance Cut notches in planking for screw head
clearance
Drill holes in firewall at proper locations for throttle and
mixture controls and fuel line Install engine— 60 to 90 re-
commended Attach fuel line Install throttle and fuel mixture
control cables Check for free movement
Install the radio equipment (receiver, battery, servos, etc ) as
per the manufacturers instructions
Make cut outs in FRONT COWL for exhaust, glow plug, etc
Cement to rear cowl and sand lightly with 400 grit paper
prior to painting
Attach W-26(PLY) L.G DOORS to main landing gear wire
as shown on plans , Install main wheels and tail wheel
Cover the model (except cowl) with colored MonoKote, or
or cover the model with CHROME MONOKOTE, paint as per
color desired and then scribe panel outlines
Paint cockpit with flat black Install pilot (not furnished) Trim
and install vacuum formed gun ports and canopy See plans for
adhesives to use Apply markings furnished
Check radio carefully, including range check per manufacturers
instructions Check Center of Gravity Do not deviate from
position shown on plans If you are not a proficient R/C pilot,
get the help of one See warning on page 1 Save your plane-
avoid grief
Temporarily center the REAR COWL on fuselage so that the
mounting holes are at 45° to the vertical and horizontal center
lines of the fuselage Mark location of holes with soft pencil
Remove cowl and drill 1/8" DIA holes thru at marks
Drill a 3/16" dia hole in the center of each F 23(PLY)
piece Press a #4—40 blind nut firmly in each one
Fasten the rear cowl in place with four #4-40 x 3/4"
R H M S Use the F 21 (PLY) with blind nut inside the
fuselaqe
With wing bolted in place, form and fit wing fillets W-23,
W-24 and W-27 All fillets on each side of the wing must
be done at the same time for proper fitting W 23's are
fixed to the wing while W 24 and W 27 are fixed to the
fuselage Smooth joints with Dap
