Assembly Instructions for the F35 Joint Strike Fighter
Note: During assembly of this model, you must at all times strive to keep the weight as
low as possible. This kit has been designed to build easily and fly the same. Excess
balsa, glue and any other components will only add to the weight and decrease the
performance.
This kit is built using taileron control, therefore a computer radio is required. If you do
not have a computer radio, an electronic mixing V-Tail unit can be used. Let’s get
started:
FUSELAGE:
 Identify all the laser cut parts and using a sanding block, remove any burrs around each
part.
 Remove the hatch and canopy from the fuselage.
 Using warm water and soap, thoroughly wash the entire fuselage, hatch and canopy,
both inside and out. Also wash the intake and exhaust ducting. Let dry completely. This
will remove any remnants of mold release wax that may still be on the parts.
 Using a rotary tool, cut the openings for the intake and exhaust ducting. Leave approx
1/16-1/8” lip around the face. This will be sanded and smoothed out after the intake is
installed.

 Using a rotary tool, remove the two face’s in the engine hatch compartment and engine
hatch to allow clearance for the ducting. Leave approx 1/8-1/4” lip around the edge.
TAILERON SERVO MOUNTS:
 Locate the taileron servo mount formers (2 F6’s, T1, T2).
 Trial fit together T1 and T2 to the spacer F6’s per the image below.
 Glue the sub assembly together using 5 minute epoxy, keeping assembly square
 Repeat for the opposite subassembly ensuring both subassemblies are mirrors of each
other
 Mount the taileron servos per the image below (mini servo’s are recommended).

 Slide the taileron sub assembly into the fuselage until snug.
 Glue in place using epoxy.
INTAKE DUCTING, ENGINE MOUNTS AND MAIN GEAR MOUNTS:
 Locate the following laser cut components:
F3, F4, EM, MGM (or FMGM), F3-S, F4-S, and F4-S2
 Glue F4-S and F4-S2 to former F4. Glue F3-S to former F3.
 Using 5 minute epoxy, double up the Engine Mounts (EM). Trial fit the EM’s into the
notches in F3 and F4 to verify the fit. Sand if necessary to obtain a snug, but not tight fit.
 Trial fit together F3, F4, both EM’s and both MGM’s (do not glue together the MGM’s
at this time). Disassemble when satisfied with the fit.

 Trial fit the intake ducting into the fuselage ensuring each part is positioned as far
forward as possible.
 If required, use a dremel rotary tool with a grinding wheel or a file to carefully remove
any of the corner filler inside the fuselage so the intake slides in place to the end.
 With the intake ducting in place, trial fit former F3 in place supporting the back end of
the ducting. Former F3 should be located flush with the end of the ductings.

Oakdale Aircraft F35 Construction

 Trial fit former F4 in place with the Engine Mounts (EM) in place. Former F4 should
be past the rearmost panel line of the main gear doors. If it is not, adjust the intakes and
former F3.
 With F4 temporarily in place, cut an opening in the side of the fuselage for the wing
spar to pass through and connect to F4.
Retracts, Fixed Gear, or No Gear
 If installing retracts, double up the Main Gear Mounts (MGM) using 5 minute epoxy.
 Temporarily mount the retract units to verify the mount and method of retraction.
 If you are installing fixed gear, use the FMGM’s instead of the MGM’s.
 If you are not installing gear at all (for bungee launch), do not use either the MGM or
FMGM. You will install a bungee plate at a later time.
Intake Preparation
 Using a hobby knife or razor saw, remove approx 1/4" from the inside edge of each
intake to provide an overlap over the fan unit. Also, remove material where the nose
cone of the fan unit will reside.

 Tape the two inlets together along the inside edge and temporarily fit it to the fan
shroud. Trim the inlets as necessary to ensure a proper fit.
Toki .18 Fan unit shown
 When satisfied with the fit between all of the intake and former components, prepare to
glue them in place.
 Using 30 minute epoxy or epoxy resin (recommended), produce a mixture with a
microballoon filler until it is of a thick, pasty consistency.
 Apply the mixture to the inlets of the fuselage where the intakes will be glued.
 Slide the intakes in place and ensure they are positioned as far forward as possible and
are glued all the way around. Remove any excess resin before it cures. Don’t worry
about shaping the intakes right now. This will be completed after the resin has cured.
 Slide in place former F3 to support the intakes while they cure. Using medium CA,
temporarily tack the intake to the former to ensure proper positioning.
 When the intake has cured, glue former F3 to the fuselage and let cure.
