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.

BUILDING INSTRUCTIONS
Before starting to build this kit, we urge you to 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 experience to
take on this model. However, every minute detail is
not covered. This is not a basic trainer. The
instructions together with the simplicity of this kit
will allow you to produce a first class EX-TREME
330 3-D.
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
Washable marker
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 EX-TREME 330 3-D.
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 possible.
Use a ruler to measure to make sure distance A -
B and C – D are equal. This is important to make
sure the plane tracks straight and predictably.
2. Use a washable marker to mark the location 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 bottom of the
fuse with two 2mm x10mm 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 2 CA
hinges and pink zap.

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 and one throttle servo
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.
The aileron servos should be located to the
outside of the servo trays from the fuse, the
throttle servo needs to be close to the fuse.
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 2mm x
20mm machine screws and backing plates.
13. Trim a hole using a sharp hobby blade, just
behind the radio hatch on each side of the wing,
aligned with the servo, for the aileron control rod.
14. 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 left 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 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 the included wire tube , two brackets, and 4- 2mm
x10mm screws to hold the wires down the length of
the fuse
22. Cut the tube at an 11degree angle on one end.
23.
24. Lay the angle cut on the tube on the bottom of
the wing next to the fuselage with the back end of
the tube just in front of the bottom servo. Mark
the position for the hole and cut a notch in the
bottom of the wing next to the fuselage 3/16"
wide and 1/2" long for the rudder and elevator
servo leads to exit the wing into the

tube.
25. Attach the tube to the side of the fuselage with
the two brackets and 4 sheet metal screws. You
can now run you wires from the rear servos
through the tube into the wing.
26. 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, then drill for the 3mm engine mounting
bolts.
27. Mount your engine to the fuse with 3mm x
20mm 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.
28. Prepare and install a servo wheel on the throttle
servo as was done with the control surfaces.
Make sure your servo is at low position and the
travel matches up with the travel of the

carburetor.
29. Drill a small hole in the leading edge of the wing
for the throttle control rod to exit, then slide 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.
30. Install an “EZ” connector on the outside position
of the servo wheel, 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.
31. As an option, you can use a micro servo on the
throttle. Remove the covering from the area just
behind the engine with a sharp hobby blade.
32. Secure the servo with the screws supplied.
33. Use a servo horn as is described above.
34. 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.

35. Drill the holes for the gear, then install the gear
using the 3mm x 30mm bolts and lock nuts.
36. Install the axles in the end of the landing gear
using the 4mm lock nuts.
37. Install the first collar and set screw on the axle.
38. 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.
39. Lay out the parts for the fuel tank assembly.
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.
40. Bend the long fuel tube so 1/3 of it is bent up at
45 degrees.
41. 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.
