2.Keep it away from high temperature environment and corrosive chemicals for storage and flight.
(the operation temperature: from:-10℃to 50℃)
3.If you are not an experienced pilot or have not flown this type of model before, we recommend that
you get assistance of an experienced pilot for your first flights. Please avoid flying with other RC
models with same frequency.
4.Please choose a open flight area and use the training gear set for your first fight in order to minimize
your loss due to control mistakes.
1.To avoid the loss of the property of others, please keep away from high tension power lines, high
buildings or any other obstacles while flying！
2.Keep away from crowds in case of accidents！
3.Do NOT operate in rain, thunder, storms, lighting, strong wind or any other bad weathers to ensure
your and the helicopter’s safety！
4.Please avoid using in a bathroom or a rainy day to prevent moisture or water vapor from entering the
helicopter inside which may lead mechanical or electronic components malfunction and cause unex-
pected accidents！
5.Do Not re-equip, upgrade or repair your helicopter with the accessories outside the DTS parts catalog
in order to ensure the safety of the model structure!
6.Keep people and objects away from the spinning unit and parts in case of damage or injury!
1.Please make sure the helicopter frequency will not interfered with others before every flight.
2.You should confirm the batteries of your transmitter and helicopter are fully charged before every
flight and your first flight.
3.Both the throttle stick (left-hand stick) and throttle trim MUST be in their lowest position before every
flight. Each time before your flight, you must ALWAYS turn on the transmitter power first before con-
necting the flight battery to the receiver. After your flight, you should disconnect the flight battery from
the receiver before turn off the transmitter.

Pre-Flight Controls Test
1.Control Test: Throttle
2.Control Test: Elevator
Push the throttle stick upward till the motor start to spin. Ensure the motor spins anti-clockwisely while the main blade
spins clockwisely.
Please don't push the throttle stick upward over 1/5. The motor will spins at high velocity if the throttle stick is over
pushed. This may cause damage on the product or self injury. Besides flight operation, when performing mainten-
ance or adjustment and fine-tuning indoor, please remove the connection between the motor and the ESC. This
can prevent the motor from unpredictable spinning and cause acidents.

Disconnect the connection between ESC and motor, turn on the power of the transmitter and helicopter, move the
pushrod to check the sercos direction.
1. Hold the helicopter rotates around the main shaft, gyro will control the tail servo to compensate the movement of the
rotation direction.
E.g. When helicopter tail rotates rightward, the gyro will control the tail servo to rotates the tail leftward. (Picture A)
2. Hold the helicopter and tilt the fuselage to a certain direction, the swashplate will be tilted toward the opposite
direction of the fuselage.
E.g. When the helicopter tilted forward, the swashplate will be tilted backwards. When the helicopter tilted backward,
the swashplate will be tilted foward. (Picture B)
If the helicopter tilt laterally, the swashplate will be corrected in the opposite direction. (Picture C)
When the fuselage return to the initial horizontal position, the swashplate will also return to the initial position.
