HOW TO FIX YOUR TWIN ROTORS
If the linkage between your twin rotors comes undone and is dangling below the bottom rotor,
it is very EASY to fix!
(A)
Carefully re-attach the linkage back onto the top connector and gently push it into place.
(B)
While your there, you might want to check around the area for any fibers or debris that might
affect your flight performance. Carefully remove it with tweezers and you are ready to start
flying again!
A
WRONG
B
RIGHT
- During Car Mode, gently push the throttle stick up to make the
helicopter cruise.
- When the helicopter is cruising, push the LEFT or RIGHT Transition Button
once to activate the flight mode. Slowly push the throttle stick up to make
helicopter fly.
- DO NOT look at the controller/charger but focus on the helicopter.
- As soon as the helicopter leaves the ground, reduce the throttle slightly.
- Make slow gentle adjustments when reducing or increasing throttle.
- VERY gently add throttle if the helicopter goes down.
- VERY gently reduce throttle if the helicopter goes up.
- For turning, give short and small inputs to the direction stick (most beginners
will easily over control the helicopter).
- For moving forward, turn the helicopter pointing to more open space before
pushing the forward buttons.
NOTE: The helicopter won’t hover even if the throttle is positioned at
maximum in Car Mode.
The helicopter will be in car mode by default under the following conditions:
1. The throttle is positioned at minimum.
2. The helicopter and/or the controller/charger is restarted (switched "OFF" and
then switched back "ON").
3. LIFT-OFF PROCEDURE (after Trimming procedure):
Ground Cruising:
Put the helicopter on a smooth surface. Slowly increase the throttle. Slowly
push the throttle stick up to make helicopter cruise faster (pic.14). Slowly
push the throttle stick down to make helicopter cruise slower (pic.15).
4. FLIGHT CONTROL:

Hover down
Accelerate & Decelerate:
If you turn the helicopter slowly counterclockwise, the helicopter will decelerate. And if you turn it clockwise, it will accelerate.
Turn counterclockwise and clockwise:
Slowly push the direction stick left to make the helicopter turn
counterclockwise (pic.16). Slowly push the direction stick right to make
helicopter turn clockwise (pic.17).
To hover up or down:
When the helicopter flies steadily, you can slowly push the throttle stick
up to make helicopter fly higher, or release the stick a bit to make the
helicopter fly lower. Only small amounts of stick position change are
required for smooth flying. (pic.18 & pic.19)
Turn counterclockwise and clockwise:
Hold the helicopter at a height. Push the direction stick toward the left to
turn counterclockwise (pic.20), and push the direction stick toward the
right to turn clockwise. (pic.21)

HOW TO ADJUST YOUR HELICOPTER’S FLIGHT PERFORMANCE
5. FLYING INDOORS
Location
– Fly in a wide-open room [ideally over 10 ft (W) x 16.5 ft (L) x 8 ft (H)], away from breakable items. Avoid flying near vents and/or fans, as these may
overpower the Havoc Razor™ helicopter and make it difficult to control.
NOTE:
Always get permission to fly your Havoc Razor™ helicopter indoors.
CAUTION:
Never fly near your face. Keep rotor away from your fingers, hair, eyes and other body parts. Always lift off from a flat surface. Never hold the flying
heli in your hand when lifting off. DO NOT launch heli near people or animals. Stay away from obstacles and electrical hazards.
FORWARD WEIGHTING
Stick the CG Adjuster
label here to obtain
different performance.
Optional
CG Adjuster labels
If you would like to adjust the directional
control of your Havoc Razor™
helicopter, you have the option of putting
on the optional CG Adjuster labels. Stick
one label on the bottom of the
helicopter’s nose as needed. These will
forward weight the helicopter and allow
for a different flight performance.
