Thank you for purchasing TF model's 800 size Gazelle. We hope that it will bring you a great flying enjoyme
Please read instructions thoroughly before assembly of the heli fuselage.
Mechanic Assembly.
This Gazelle must use TF Model's won design mechanic, other mechanics will require extensive modifications
and will have to be performed by the customer themselves.
Packaged with the mechanic parts is an exploded view drawing for assembling the mechanic. Please follow
the drawing and assemble the mechanic accordingly.
The following photos shows the installation of the servos.

installation.
Landing Skid installation
The moulded landing skids are designed be adjustable with locking design. Insert the skids into the fuselage, then
adjust them to the width that you desire then simply drill 2 M3 holes through both the skid legs and the wood skid
bearers, use M3 nuts and bolts to secure the skid legs.
The red circles shows the 2 locations
for sercuring the landing skid legs.
Do the same for the rear skid legs.
Slide the skids into the skid legs and
secure with sheet screws.
Mechanic Installation into Fuselage.
The Gazelle comes factory installed formers and bearers for our mechanic, simply drop in our mechanic and slide
along the bearers to correctly locate the main shaft. After correctly locating the main shaft, mark the 4 holes for securing
the mechanic and drill through. Then secure the mechanic onto the bearers using M3 X 24 mm bolts and lock nuts.
Locate the top cover in photo.
With the mechanic sitting on the bearers
and the rotor head removed, put the top
cover onto the fuselage. Use tape to
temporarily secure the top cover.
Slide the mechanic until the mainshaft
sits at the central location of the top
cover hole.
Mark the 4 holes onto the bearers for drilling.
Use M3 nuts and bolts to secure the mechanic

Drill 1 mm holes at desired locations on
the top cover to secure it to the fuselage.
Tail Fan Unit Installation.
The tail fan unit comes installed from the factory along with the belt and motor drive.
Before gluing the tail onto the fuselage please check and adjust the belt tension.
This can also be done after the tail has been glued on via the access hatch too.
IMPORTANT !
We recommend that you test the rotation direction of the fan unit. The blades should
rotate towards the rear of the helicopter to be correct.
You can now glue the tail unit onto the fuselage, simple !!
After gluing the tail unit, now install the rudder servo onto the factory installed rudder holder.
The push rod is also installed just adjust the push rod to the correct length and install
onto the rudder servo.

Dummy Engine, Stabilizers and Accessories
Glue the dummy engine onto the fuselage
as in photo. Take care not to glue the
front of the dummy engine to the top
cover. The top cover needs to be removeable.
Photo shows the rear location of
the dummy shaft drive.
Refer to the above photo for the front
of the shaft drive.
Photo shows the locations for gluing the
dummy shaft drive supports.
Photo shows the layout for gluing the
horizontal and vertical stabilizers.
Setting Up of the IDTS (independent Tail Rotor Drive System) for Flying
Hook up the tail motor to the ESC and test for the correct rotation direction of the tail rotor.
After testing then plug the tail rotor ESC into an Aux channel on the receiver. Now test the main rotor
rotattion direction. Plug the main rotor ESC into the throttle channel of the receiver.
Now use the mixing function on your transmitter to activate both the throttle and the auxiliary channel.
The throttle channel is the master and the aux channel is the slave. Set the curve for the tail rotor motor
flat at 80 % at the beginning. You can set this higher if desired, but not lower. Set the main throttle curve as you
normally would any other helicopters. Remember to assign the switch to switch on this mixing.
You are now setup ready for your first flight !!
