WING
TAIL
Rudder
1.Carefully and slowly insert the main wing into the
fuselage then center it in place.
2. Glue the CFK rods on Aileron, Rudder and Elevator
as indicated.
4. Install four CA hinges on the aileron as shown,
carefully use the sharp hobby knife to cut the slots on
aileron and trailing edge of wing for the hinges.
5. Attach the aileron to the trailing edge of main wing
then apply CA glue to all hinges and make sure
they are jointed well. Do the same procedure on
the other aileron.
7. Glue the FRP control horn and elevator reinforced
plates together as shown. Make sure the two
rein forced pieces are glued properly at each side of
elevator so the control horn could be installed
perpendicularly at left.
8. Do the same procedure as elevator control horn
to install the rudder control horn as shown at right.
10. Cut a slot at the bottom rear fuselage, install tail
skid in place with CA glue.
11. Drill 5/64”(2mm) pilot holes for mounting the
elevator servo, next connect a 12” extension wire
before you secure the servo in place. Do the same
way on rudder servo.
3. Install and center the horizontal tail in place, make
sure the horizontal tail is perpendicular to the vertical
fin and parallel with the main wing. Next CA the main
wing and horizontal tail firmly in place.
12. Locate the pushrod and clevis, thread the clevis
6. Install four CA hinges on the rudder, use the same
way as you did on aileron. Next glue the rudder on
the vertical fin.
4
9. Do the same procedure on both aileron control horns.
at least 6mm then snap onto the FRP control horn,
make sure servo is in neutral position then make
Z-bend and cut the excess pushrod. Insert the
Z-bend end to the servo horn and secure the servo
horn on the servo as shown. Do the same way to
the other pushrod.

MOTOR
LANDING GEAR
13. Secure the aileron servo and attach the aileron
pushrods as shown.
14. Secure the cross mount on brushless motor with
four 3x6mm sink screws. Install the adaptor to the
brushless motor with three 2x6mm screws as shown.
16. Open the hatch and place the Lipo battery in the
compartment. Secure the battery in place with the
2.3X12mm wood screw.
17. Connect the receiver and controller properly,
secure these electric devices with the furnished
wide Velcro.
19. Apply the furnished glue on fuselage opening
and Velcro, wait for 10 minutes before gluing them
together. Hint: It is very important to wait for couple
minutes before gluing together. You may blow the
glue area and it will be cured faster. Do not
separate the Velcro. Carefully attach the Velcro to
the fuselage opening on one side first then apply the
other side of fuselage to the Velcro.
20. Locate the landing gear wires, mounts, wheels
and stoppers. Bend the wire as shown and trim the
excess wire.
22. Trial fit the landing gear wire and mount first,
CA the wire and landing gear mount in place
when satisfied. Note two landing gear wires are
angled properly.
23. Install the wheel and CA the wheel stopper. Make
sure wheel rotates freely.
15. CA the firewall in place then install the brushless
motor on the firewall with four 3x10mm wood screws.
Next install the furnished propeller and with prop nut.
If user would try extreme 3D then APC 10x4.7
SF is recommended.
18. Locate the narrow/long Velcro strip and trim as
shown to accommodate the fuselage opening.
Note: do not cut it off and make sure it is connected.

21. Locate the landing gear mounting slot where
near the leading edge of main wing as shown.
Congratulations! Now you are ready to fly. Make
sure to adjust the plane as the suggestion in next
two pages.

LONGITUDE BALANCE
C.G. Must be set on thrust line
C.G. is too low C.G. is correct
As 3D planes do a lot of hovering so it is very important to do longitude balance to make hovering much
more stable. Try to create a small hole after the motor and on the thrust line. Get music wire or string then
thread the wire through the hole. Make sure that model hangs perfectly vertical as illustration. If not then
try to adjust the location of battery, receiver or ESC to get good longitude balance.
BALANCE
It is important to balance the plane to get correct C.G. before you fly.
Balance Point as indicated in each diagram.

Congratulations
Your done, may you have many successful flights filled with fun and lots of 3D maneuvers.
Thank you for purchasing this plane from Thunder Tiger and we look forward to providing you with other
great R/C products in the near future.

SETUP
Exponetial
To make your 3D flight successful, the most important
is to set up your radio properly and fine-tune the
exponential. We would suggest that could show the
exponential graph as the illustration.
Normally this computerized radio has dual rates or
even triple rates. Once you fly it fine with low rate in
normal flight. Next you will have to set up 3D rate.
We suggest the 3D-rate setting is same as low rate
setting around 1/3 of the total stick travel in the
beginning. If you look at the graph , the middle section
of 1/3 travel are most likely the same at low rate and
3D high rate .Beyond this middle section the 3D rate
setting is far higher than the low rate.
SIMULATOR
FLYING
Even though you set up the airplane , it needs to be
setup and fine-tuned in the air. Always start on low
rates when launch the airplane or take off of the
ground. Once you fine trim the airplane in the air then
tune the exponential setting, you will be able to fly it
all the time on the 3D rates.
Once you got confidence to do hovering or do 3D
aerobatics, we suggest you fly it near you. The closer
the airplane, the better you fly it near you. The closer
the airplane, the better you can control the plane as
you can see it very clear even if it has a slight
movement. The other advantage is the lower or closer
to ground, the less potential energy. It is useful for a
dead battery or ESC cut off suddenly.
A good tool to practice 3D easier is to fly simulator.
One may say simulator is not realistic but this is not
true. There are some simulators available in the
market and its scenery and performance are just like a
real thing .For example, Aerofly Pro Deluxe USB
version from ikarus or Real Flight G3 from
Greatplanes are all good simulators you can choose
from .
Simulator is a must buy tool if you seriously want to fly
3D aerobatics. There is no genius or born 3D pilot,
remember that practice makes perfect.30 minutes a
day on a simulator can help you do hovering, torque
roll easily as well as other aerobatics. If you would like
to be a good 3D pilot, flying everyday is necessary.
The reaction to control the airplane will be more
nature. As there is no time to think when you do 3D
aerobatics.
Simulator practice might be perfect yet suggest to do
some actual flying as the supplemental so it will not
go too far from the real thing as there are many things
that you can not learn in screen.
