The Extra 330L kit is precisely crafted to produce an airplane that is capable of winning at the highest levels of
precision aerobatic competition. It should only be flown only by radio control pilots experienced with this type of high
performance, low wing airplane at flying sites that comply with the standards set by the Academy of Model
Aeronautics or other nationally recognized radio control sanctioned organizations.

AirWild will repair or replace individual parts, or all, of the kit for defects in material and / or manufacturing for a
period of thirty (30) days or until the customer builds the kit whichever occurs first.

This manual divides the assembly into several sub-assemblies; fuselage, stabilizer, wing, fin, landing gear, etc.
Please read each section carefully and familiarize yourself with each step before starting on the particular sub-
assembly. Photos and illustrations are provided in this manual to clarify and detail many sub-assembly steps. The
two should be used together to facilitate your assembly.

F Some General Guidelines To Follow When Working With A Composite Airplane
1. There may be some small loose fragments of harden epoxy resin or balsa shreds caught inside the structure of some
components. Most of the time you can free them loose from cut-outs or slot opening. However should you find unable to shake
loose the last few remaining bits, we often find squirting some thin CA into the structure where the loose pieces are could
conveniently glue them in place.
2. When cutting into the composite skin, always do a round corner instead of a sharp transition. This will reduce chances of cracks
developing from the corner.

Remove fuselage from the shipping box and place it on a flat working surface. Refer to the following illustration to
familiarize yourself with various key features of the fuselage before attempting to assembly the airplane. A good
preparation goes a long way.

An integrated cowl ring is built into the cowl to facilitate mounting of cowl. Cowl is secured to the fuselage through
the use of four (4) M3 x 12 socket head cap screws.
Screws are attached from the inside of the fuselage as illustrated in the photos below (for illustration only, not actual
Extra 330L). Use of a ball-tip hex key would be most convenient to access the socket head screw at an angle.

Since there are many excellent choices of engines for this airplane, we did our best to design the engine box to
accommodate various types of engines available. Use the following dimensional drawings in conjunction with your
engine’s outline specifications to determine the correct length of spacers needed to set up your particular engine.
Please carefully consider this issue before proceeding.

Doc. No.# AW70-105-01, Copy Right 2005, AirWild Hobbies, Inc. page 8of 8
Use the reference lines noted above to identify the offset center mark for your engine mount. Mark the bolt pattern
for your particular engine based on the center reference. Please note that there is approximately 2.5-degrees of
right thrust offset built into the engine box design. For illustrational purpose we have provided an installation diagram
for mounting a DA100 twin-cylinder engine which we used for prototyping. Make appropriate changes to the length
of the stand-off for your choice of engine.
Obviously there are various ways to construct engine
spacers. However we find the following method to very
simple and effective. Don’t mind giving them a try:
Stand-off Fabrication: Obtain 0.75’‘ ~ 1’‘ diameter
wooden dowel from your local hardware or lumber
store (ie. Home Depot). Cut dowel to the desired
length. Make sure they are all of even length. Use a
drill press to do the next step. Drill a center hole of the
appropriate diameter for the engine mounting bolt
through the dowel. Next, saturate the through hole and
two ends of the dowel with thin CA. This will prevent
the dowel from splitting under pressure. Repeat same
steps to fabricate three more and you’re done.
Different brand and size of prop may require you to adjust right thrust accordingly. For our prototype setup
(DA100, NX 28x10) we added some minute amount of additional right thrust by shortening the right stand-offs.
Left Stand-off Set: 30 mm long
Right Stand-off Set: 29 mm long

rFuselage 1rAluminum Landing Gear 1
rSocket Head Cap Screw, M4x16 4rLock Washer, M4 (optional) 4
rGear Fairing 2rAdhesive-Back Velcro (optional)
Place the fuselage up side down and locate the main landing
gear block. Note that four blind nuts for securing the main
landing gear have been pre-installed. Remove the main landing
gear from the shipping box and you will notice that it also has a
matching hole pattern. Simply secure the main landing gear to
the landing gear block using four (4) M4 x 16 socket head cap
screws and washers. To protect the composite surface from the
harsh wear of landing impacts, we actually added a piece of thin
fuel-proof foam sheet underneath the landing gear. In this case
we use a sheet of automotive gasket for this purpose.
Next you are going to add the gear fairing. Your kit comes with
one set (left & right) of gear fairing. The bottom of fairing has a slit. You can pull open bottom of fairing at the slit to
install without having to remove the attached landing gear. Get some adhesive backed Velcro for this installation;
1. Cut a piece of Velcro just long enough to adhere to the inner ball of the fairing. This can be either the hook or
loop part of the Velcro. Whichever you choose to use you will need the mating part for later.
2. Spread open fairing at the slit and mount it to the installed landing gear. Mark on landing gear the end of
fairing (where Velcro tape is).
3. Cut two pieces of mating Velcro and tape them to top and bottom portions of the landing gear at the marking.
4. Tape up slit with a piece of clear 3M tape. This will prevent fairing from flapping in flight.
5. Reinstall fairing. Now it is held to the landing gear by the Velcro tape.
6. If you do not expect to remove landing gear frequently, add a thin bead of silicon caulking between top of
fairing and fuselage to cushion the parts and hold them together more securely.

rClear Canopy 1rCanopy Hatch 1
Clear canopy has been pre-trimmed to size. Simply position the canopy
over the hatch and align it to the recessed layout. Once you are satisfied
with the position, glue it to the hatch cover with adhesive such as RC56,
Zap-A-Gap-A-Goo or Liquid Nail. These types of adhesive give you
ample time to work with positioning the canopy, yet once hardened any
excess can be easily trimmed off with a sharp blade.

Trial fit a main wheel with a wheel pant. Enlarge the wheel cutout if necessary to assure an unrestricted rotation.
Install axles onto the landing gear. Position wheel pants onto landing gear. Adjust them to the correct seating angle
and mark on wheel pants position for the wheel pant hold-down screws.
Remove wheel pants and drill a pilot hole at the mark. Enlarge the pilot hole for mounting a 6-32 blind nut into the
plywood piece that’s on the inside surface of the wheel pant. Use thin CA to secure it in place.
For final assembly, mount the wheel pant with ∅5/32’‘ wheel collars and ∅4’‘ wheel. Secure the wheel pant to
landing gear with a #6-32x1’‘ socket head screw into the blind nut. To obtain a flush mount you may want to install
a piece of spacer between the landing gear and wheel pants.
