BALANCE
With the radio system still on, move the throttle trim
lever up the middle. This should open the carburetor
barrel up slightly(1/32"-1/16") and allow the engine to
idle satisfactorily. To shut the engine off from the
transmitter, simply move the throttle stick and trim lever
all the way down. Now move the throttle stick up and
watch the carburetor barrel. It should reach full open at
the same time the stick reaches it end point. If it does
not follow the instructions below. If the barrel does not
open all the way, move the pushrod in one hole in the
carburetor throttle arm. If the carburetor barrel reaches
full open and makes the servo " hum" very early in the

IMPORTANT- Do not attempt to fly your model before
completing this every important section. A model that is
not properly balanced will be unstable and could cause
serious damage and /or injury.
The balance point for this model is 4-1/8’' behind the
leading edge of the wing. Measure this distance and
mark it on both sides of the fuselage right under the wing.
With your model fully assembled but without fuel, pick it
up with your index fingers at each of the two balance
marks you made earlier. If balanced properly, the plane
will hang horizontally. If the plane hangs with the tail
down, then you need to add (or redistribute) some
weight in the nose. Usually the plane will either balance
or hang slightly tail heavy. The easiest cure for a tail-
heavy plane is to move the receiver and battery forward
as far as possible. If the plane hangs nose down, then
you need to add some weight to the tail. Stick-on lead
weights are available from your hobby dealer that will

If you are an experienced pilot, some of the following
text will not apply to you. Simply disregard references
to “your first flights”.
LOCATE A GOOD FLYING SITE
Generally, the best place to fly your model is at
AMA
(Academy of Model Aeronautics) charactered club field.
Your local hobby dealer can tell you if there is such a
club a club in your area or write the AMA for information.
It is also a good idea to join this organization before
flying your model since they offer liability insurance that
can protect you if your model causes damage or injury
to others.
If there is not a chartered club field in your community,
you will need to find a large area free of obstructions,
which has a smooth grass or asphalt surface to be used
as a runway. For safety's sake, it should be located well
away from houses, building schools, power lines and
airport. If you will be flying within 6 mile of an airport,
you should check with the airport manager before flying
your model.

The batteries are the heart of your radio system. Make
s u r e y o u h a v e f u l l y c h a r g e d b a t t e r i e s ! W i t h
rechargeable batteries, follow the manufacturers
instructions to make sure the batteries are fully charged,
especially the first time the radio is used.
If your radio uses dry cells, make sure your batteries are
in new condition. You have a lot of money invested in
this project so it is not worth the risk of using old
batteries.
A NOTE ON BATTERIES
You should perform these checks before each flying
session.
1. Check all control surfaces for possible looseness or
deterioration.
2. Check all screws, rubber band, clevises, nuts and all
other connectors to make sure they are securely
fastened.
3. Check which radio frequencies are being used. Do not
turn your radio until absolutely sure you are the only one
operating on that frequency.
4. Check for proper operation of all control surfaces.

33.Wrap your receiver and battery with packing foam
which is available at local hobby shop. Install the
receiver and battery in the front of the servo tray.
Receiver is near the servo tray and battery is far from
the servo tray as shown.
Drill a 1/16'' hole through the fuselage side, about one
inch behind the switch mount. From the inside out,
thread the receiver antenna through this hole. You may
want to tie a knot in the antenna 3'' or 4'' from the
receiver to act as a strain relief. Attach the end of the
antenna to the top of the vertical fin with a small #10
rubber band and a T-pin. Maintain only a slight amount
of tension on the antenna wire.
34.Correctly install the prop in front of the spinner
backplate using the engine prop washer and prop nut.
Note that the spinner backplate has two little posts that
must be rotated up against the prop blade before the
spinner will fit on. Rotate the prop counter clockwise
until it is vertical when it is against the engine's
compression stroke. Securely tighten the prop nut using
a prop wrench or correctly fitting wrench. It is not a good
idea to use pliers when tightening the prop nut! Attach
the spinner to the spinner backplate using the two
3x12mm self tapping screws provided.
Make sure the direction of servo moves correctly. If not
switch the reversing switch on the transmitter. If the
control surface does not move far enough, either move
the pushrod out farther on the servo horn or move the
clevis in farther on the control horn. If the control
surface moves too much, either move the pushrod in on
the servo horn or move the clevis out farther on the
control horn. Adjust the control throws as following
suggested.

Grasp the throttle pushrod, and while looking at the
opening in the top of the carburetor, adjust the pushrod
until the throttle barrel( inside ) is all the way closed.
Tighten the setscrew in the pushrod connector to secure
the pushrod in that postion. Cut off the excess throttle
pushrod approximately 1/2" past the EZ connector.

Congratulations!! Now the Tiger Stick is
ready to fly. Pease do the radio movement
check as well as the balance and contrl
throw before you go to fly. All Thunder
