Important Information
Covering coming loose is not COVERED UNDER WARRANTY. Due to temperature changes the
plane may develop some wrinkles in the covering that you will need to remove with an iron. Be sure
to seal the edges down first so that you do not cause the covering to shrink and leave exposed
areas of wood. Please inspect the plane before beginning to assemble to make sure you are happy
with it. After assembly has begun you cannot return the kit. If you find a problem before beginning to
assemble the plane you must contact us, please do not return it to the dealer.

Congratulations on your purchase of the
Radical 330 ARF. Every effort has been made
to produce a lightweight, straight, easy to
assemble aircraft. Because of its oversize con-
trol surfaces which are double beveled to allow
for extreme throws, great care must be taken in
the set-up and flying of this airplane. Quality
hardware components have been provided to
allow for 3D set-up while maintaining adequate
mechanical advantage to eliminate flutter. It is
your responsibility as an advanced pilot to fly
the aircraft in an intelligent manner. THROTTLE
MANAGEMENT IS A MUST!!!!!!! Lanier RC
has flown the Radical 330 ARF through a very
rigorous flight-testing schedule and have
stressed the airframe beyond all practical
parameters without a single failure. Lanier RC
will NOT warranty the Radical 330 ARF against
flutter due to improper set-up or excessive
speed maneuvers. having said that, we believe
you will find the Radical 330 ARF to be one of
the most responsive, in-the-grove aircraft on the
market. Just remember to use common sense
when flying this high performance machine.
We are very proud of the construction of the
Radical 330 ARF and all of our other ARF air-
craft. Each aircraft is jig built to insure a straight
true airframe. Every effort is made to build as
light an aircraft as possible. As with any profes-
sional builder, glue is used sparingly. Please
take a moment during assembly and run a
bead of CA or aliphatic resin into the high
stress joints that you can reach such as the
landing gear plate, servo mounting trays,
wing hold down blocks, Firewall, etc. Also,
during the course of shipping from the manufac-
turer to our facility in the United States, it is not
uncommon for the aircraft to experience several
changes in climate. This may cause the iron-on
covering to develop wrinkles. This is not a fault of
the manufacturer. Please take a few minutes with
your heating iron and heat gun to iron down the
seams and re-shrink the covering where needed.
The results will be a beautiful aircraft with a
breathtaking finish that you will be proud to dis-
play at your flying club.
Before beginning assembly of your Radical
330 ARF, we highly recommend that you study
this manual in its entirety. You should begin
planning your radio installation based on your
choice of engine and equipment from the begin-
ning.
Because the Radical 330 ARF is intended
for those with some degree of modeling
experience, every minute detail will not be
covered. This is not a basic trainer.
Assembly of this aircraft will be easy for the
experienced modeler, and by following the
instructions within this manual and using
the skills you’ve gained during your model-
ing career you will be able to produce a first
class aircraft.

read through these instructions. They contain
some important building sequences as well as
instructions and warnings concerning the
assembly and use of the model.
We expect that you have some building experi-
ence to take on this model. However, every
minute detail is not covered. This is not a basic
trainer. The instructions together with the sim-
plicity of this kit will allow you to produce a first
class Radical 330.
BUILDING SUPPLIES NEEDED
Hobby knife w/ #11 blade
Thin Zap CA
30 Minute Z-poxy
Thread lock
Wire cutters
Pliers
Drill with bits: 1/8", 5/32"
Phillips and standard screwdriver
Small clamps
Masking tape
Tape measure

Paper towels
Rubbing alcohol
See the list at the end of the instruction book for
a list of additional R/C equipment you will need
to complete the Radical 330.
1. Test fit the wing in the fuse. Make any
adjustments needed with a sanding block or
round file. Try to keep the fit as tight as possi-
ble. Use a ruler to measure to make sure dis-
tance A - B are same on both sides of the fuse-
lage and C - D are equal on both sides of the
fuselage. This is important to make sure the
plane tracks straight and predictably.
2. Use a washable marker to mark the loca-
tion of the wing in the fuse on both sides, then
remove the wing. Remove the covering from
the wing joint with a sharp hobby blade, being
careful to only cut the covering and not the
balsa.
3. Slide the wing back in the fuse, almost to
the wing joint. Coat the bare balsa at the joint
with 30 minute z poxy and slide the wing in the
rest of the way. Use your marks to realign the
wing, then remeasure A to B, and C to D.
Clean up any zpoxy that squeezed out with a
paper towel and alcohol. Block the entire
assembly on your workbench until cured.

4. Test fit the horizontal stab in the rear of
the fuse. Center it the same way you did the
wing using a ruler and make sure it square to
the wing, then mark and trim the covering from
the joint. Glue in place with 30 minute z poxy.
5. Test fit the elevator on the stab with 4 CA
hinges, then glue in place with 1 or 2 drops of
thin Zap on each side of each hinge. Clean any
CA runs with acetone.
6. Install the tail wheel bracket on the bot-
tom of the fuse with two #4 screws. Align the
wire with the back of the fuse.
7. Recess the bottom of the tail wheel
bracket to accept the steering arm for the
wheel.
8. Install the rudder on the fuse with 30
minute zpoxy on the tail wheel bracket, then 3
CA hinges and thin CA glue.

9. Install the tail wheel on the bracket using
a small inner diameter wheel collar and set
screw on each side of the wheel. Use thread
lock on each set screw.
10. Trial fit, then install an aileron on each
side of the wing with 4 CA hinges and pink zap.
Make sure the wing tip and aileron tip are
aligned before you glue.
11. Install two aileron servos in the wing.
You may need to open the servo trays to accept
the size of your servos. Use a hobby blade or
razor saw to open the servo trays.
12. Position the aileron control rods off the
servos, toward the ailerons, keeping the rods 90
degrees to the ailerons. Mark the position of
the aileron control horns, then install them with
the #4 machine screws and backing plates.
13. Use a clevis on the threaded end of the
control rod and install one on each control horn.
Lay the rod across the servo arm, then make an
"L" bend at each intersection. Trim each rod to
¼" from the bend, install in the horn, and secure
with an "L" keeper. Place a small piece of fuel
tubing on each clevis to lock in place.

15. Trim 3 arms from a 4 arm servo wheel.
Center your aileron servos with your radio, then
install the trimmed servo arms on the aileron
servos.
16. Locate the servo positions in the rear of
the fuse and remove the covering with a sharp
hobby blade.
17. Install your rudder and elevator servos in
the openings, keeping the servo tops on the
right side of the fuse. Center the servos with
your radio.
18. Trim two more 4 arm servo wheels and
install on the servos, then locate the control
horn positions as was done for the ailerons, for
the elevator and rudder, trying to keep the rod
positions 90 degrees to the control surface.
19. Install the control horns with the small
machine screws, then install and clevis and rod
on each horn.
20. Position the rods across the servo horns,
mark, make an "L" bend, then trim as before.
Secure the rod on the servo wheel with an "L"
keeper.
21. Use a sharp hobby blade to cut a small
hole against the fuse for the rudder and eleva-
tor servo wires to enter the wing.
22. Use the included wire tube , two brack-
ets, and 4 #2 screws to hold the wires down the
length of the fuse.

24. Drill for the 6/32 engine mounting bolts.
25. Trial fit your engine on the right side of
the fuse. You can open the rails up slightly if
needed. Slide the engine forward so you have
at least ¼" clearance from the front of the prop
hub to the front of the fuse. Mark the location,
remove your motor
26. Mount your engine to the fuse with 6-32 x
1" bolts, washers, and lock nuts. There is no
need to add any washers under the motor as
the right thrust is built into the motor mounts.
27. Prepare and install a servo arm on the
throttle servo as was done with the control sur-
faces. Make sure your servo is at low position
and the travel matches up with the travel of the
carburetor.
28. Connect a control rod to the servo, with
the threaded end at the carb. Use a clevis on
the threaded end to mount to the carb.
29. Install an "EZ" connector on the outside
position of the servo arm, then adjust and
secure the throttle rod in the connector. Adjust
the position of the rod and connector to achieve
the proper throw on the carburetor.
23. Cut the back side out of the rectangular
nylon tube making it a u channel open on the
back so the wires can be fitted inside. Cut an
angle on the end next to the wing so it lays flat
against the wing over the entrance hole for the
wires into the wing.

30. Remove the covering from the area just
behind the engine with a sharp hobby blade.
31. Secure the servo with the screws sup-
plied.
32. Use a servo horn as is described above.
33. Position the landing gear on the side of
the fuse with the top of the gear approximately
1" from the LE of wing and the first bend of the
gear just above the bottom of the fuse. Angle
the gear approximately 15 degrees and mark
through the holes.
34. Drill the holes for the gear, then install
the gear using the 4mm bolts, washers, and
lock nuts.
35. Install the axles in the end of the landing
gear using the 4mm lock nuts.

10
36. Install the first collar and set screw on the
axle.
37. Install the large wheel, then the second
collar and set screw to secure the wheel.
Leave a small amount of space from the wheel
hub to allow the wheel to turn freely. Use
thread lock on the set screws.
38. Lay out the parts for the fuel tank assem-
bly. Check the tank for any debris inside, then
check the fit of the stopper. You may need to
remove some flash with a sharp hobby knife.
39. Bend the long fuel tube so 1/3 of it is
bent up at 45 degrees.
40. Assemble the stopper as shown, with the
small washer to the inside of the stopper, then
the stopper, and the large washer. Secure with
the machine screw. Just start the screw for
now.
41. Insert the bent tube through the stopper
and one of the shorter tubes. (a 3 tube is sup-
plied if you would like to use a fill line to the
tank, remember to cap this line for flight).
42. Insert the fuel tubing on straight line,
then trim to length so the clunk installed on the
end does not interfere with the back of the tank,
then insert the stopper in the tank and secure
with the screw. DO NOT OVER TIGHTEN THE
STOPPER SCREW. It just needs to be tight
enough to seal the opening.
The two pieces of balsa 1/4”x5/16”x3-1/8” are
used to space the tank out over the back side of
the throttle servo

11
43. Twist the bent line in the tank so it faces
the top of the tank.
44. Position your tank on the left side of the
fuse, directly behind the motor, with the center
of the tank level with the upper engine rail. This
height is important for the proper location of the
tank to the carburetor.
45. Mark the location of the top and bottom
indentations of the tank on the side of the fuse
with a felt marker, then drill four 3/16" holes.
46. Cut a piece of latex foam the approxi-
mate size of the tank.
47. Secure the tank to the fuse using the
included wire ties, then trim the excess with a
pair of wire cutters.
48. Cut two pieces of fuel line with a sharp
hobby blade to run from the tank to the engine,
you can drill two ¼" holes to pass the fuel line
through the fuse if you like. Secure the fuel
lines to the tank with wire ties.
49. Install your muffler using your engine's
included hardware. Secure your fuel and vent
lines on the proper fastener.
50. Install your radio switch in the bottom of
the wing, just to the rear of the receiver access
hatch. Use a sharp hobby knife to cut through
the balsa.
51. Position the radio hatch in the radio
opening and temporarily hold in place with
masking tape. Drill a pilot hole in each corner,
through the plywood corner plates. Install the
radio hatch with the #2 screws and a phillips
screw driver. Tighten the screws until the just
contact the balsa, as to not crush it.

52. Install your spinner back plate, balanced
prop, and prop nut. Tighten it securely.
53. Install the spinner cone and tighten just
snug.
54. Set the control throws initially to +/- 3/8"
for all surfaces. (After flight testing, adjust as
needed.)
55. Set the cg to 4-1/4 to 4-3/4 from the lead-
ing edge, measured at the fuse side. Keep the
cg to the front for the initial flights, then adjust
as needed.
56. Double check that all bolts are tight and
use locktite where needed, and double check
the cg, then charge your planes batteries.
57. Have fun.

The Elevator
This maneuver has your plane drop vertically in
a nose high attitude, depending on wind condi-
tions any where from a 45 degree angle in low
wind to almost backwards in higher wind condi-
tions. To perform it, at a high altitude with high
rates on, pull your throttle back and feed in the
elevator until you have the full high rate applied.
Use the rudder to guide the plane, and adjust
attitude with minor throttle inputs. You will loose
altitude quickly, to recover, apply full power and
fly out level. Watch out for getting too low or
applying too much rudder, it could cause the
plane to snap.
The Harrier
This maneuver has your plane in very slow for-
ward flight in a nose high 45 degree attitude.
To perform it, enter the same way as you would
an elevator, then feed in power until the plane
maintains altitude and starts to fly forward at a
nose high attitude. Maintain it by holding up
elevator and adjusting power, use the rudder to
change direction. Using ailerons may cause the
plane to snap and should be avoided. Add
power and push the nose back over to recover.

15
The Waterfall
This maneuver has your plane flipping around
the axis of the wing, while dropping. Starting
from a high altitude, go to low throttle and grad-
ually pull the nose up to near vertical. Just
when the plane is about the stall, give it full
down elevator and full power. Make attitude
corrections with the rudder and ailerons to keep
the plane flipping on axis. Cut the throttle and
hold full down elevator as the plane flips around
to nose high again, add power to flip it over
again. Watch your altitude as to not get too
close to the ground. Neutralize the elevator and
add power to recover.
The Blender
This is a violent maneuver that starts with a ver-
tical rolling dive that stops the descent as it
changes into a flat spin. Start at a good high
altitude, go to low throttle and push the nose
down into a straight dive. Feed in full left
aileron and complete 3 rolls, then immediately
move your transmitter sticks to an inverted snap
position, down elevator, left aileron, right rudder,
all full throw. Now feed in high throttle to flatten
the spin and stop the altitude loss. Recover by
neutralizing the rudder and ailerons, and hold-
ing a little down elevator. After you gain some
airspeed you can roll out to upright. Use cau-
tion as this is a violent and high G maneuver
that will put a great deal of stress on the air-
frame.
