2.Keep away fromcrowds in caseof accidents
3.Do NOT operate in rain,thunder, storms,lighting, strong windor any otherbad weathers toensure
,
your and thehelicopter s safety
4.Please avoid using in a bathroom or a rainy day to prevent moisture or water vapor from entering the

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 andobjects away fromthe spinning unitand parts incase of damageor injury!
1.Please make surethe helicopter frequencywill not interferedwith others beforeevery flight.
2.You should confirm the batteries of your transmitter and helicopter are fully charged before every flight
and your firstflight.
3.Both the throttle stick (left-hand stick) andthrottle trim MUST be in their lowestposition 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.
4.Please make sure that every servos function properly with correct directions after powering on.
5.Make sure every connection of pushrods is proper and the helicopter battery placed in fixed position.

Pre-Flight Controls Test
1.Control Test: Throttle
Please don't pushthe throttle stickupward over 1/5.The motor will spins athigh velocity ifthe throttle stickis
over pushed. This may cause damage on the product or self injury. Besides flight operation, when performing
maintenance or adjustment and fine-tuning indoor, please remove the connection between the motor and the
ESC. This can prevent themotor from unpredictablespinning and causeacidents.

6.Gyro adjustment
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 swashplatewill be tiltedfoward. (Picture B)
If the helicopter tilt laterally, the swashplate will becorrected in theopposite direction. (PictureC)
When the fuselage return to the initial horizontal position, the swashplate will also return to the initial position.

Main Blade Adjustment
1
DTS 450
Blade tracking is an important step to affect the flight performance. Main rotor blades that are out of track may cause vibration and
instability. Although the main rotor blades of each models are tracked at the factory, minor adjustment to blade tracking
may be required after blade changes. Thus one of the main blades pasted a coloured tracking tape to identify which blade is running
low or high in the blade tracking process.
Caution: Be sure to maintain a safe distance from the helicopter (3~5meter) when tracking the main rotor blades.
Coloured tracking tape
(From the topto the bottom)
Adjusting Pushrod When 2 mainblades stay onthe same rotatingrail,
the main bladeadjustment is completed.
2 After confirming which blade is running low and high, switch off the helicopter power supply before making any necessary
adjustments to the linkage. You can increase the pitch of the low blade by shortening the mixing arm to inner swashplate linkage.
This is achievable by turning one of the Ball Link ends in by one-half to one full turn at a time. Or, you can decrease the pitch of the
high blade by lengthening the same linkage.
3Remark: The blade you choose to raise or lower when making tracking adjustments will depend on the pitch of each blade. Open the
3D aerobatics (the tail motor power supply wire should be cut off) and the throttle/ collective stick in the middle position, both rotor
blades should be close to 0 degrees. You can easily identify which rotor blade to adjust. If one blade is lower than 0 degree, raise
it to match the other blade. If one blade is higher than 0 degree, lower it to match the other blade.
4 Generally, there is not much adjustment should be necessary to properly track the main rotor blades. If significant adjustments are
required, be sure to double-check the length of both mixing arm to inner swashplate linkages. You should also check the blades for
any damaged or twists. In fact, you should be able to get both blades tracking perfectly in the same helicopter. However, the small
defects in the ball links and threaded linkage rods/ pushrods may not always be possible to affect the blade tracking. Don't worry, the
helicopter should be able to have a good flying performance even the blade tracking is adjusted as close as possible.

Tail Drive Servo Adjustment
As this model is a precise craft, unexpected self-rotationduring flight couldbecause of severalreasons.
Could adjust throughfollowing procedure: (disconnectthe motor andthe ESC can avoid unexpected accidents)
First switch onthe transmitter.Then connect the helicopter with electricity, and tilt the rudder stick and trim to
the middle position(Figure 1); Keepthe tail driveservo boom mountand the tailboom perpendicular (Figure 2).
Adjust the position of the tail drive servo and keep the distance between the Tail Pitch Control Slider Ring and
the tail case (approximately 1/3 of the spindle) (Figure 3). Keep the servo and the servo arm perpendicular
(Figure 4).

Loosen Belt is one of the reason for tail-lock fail besides gyro setting. Adjust by following the above:
Loosen the screws that mounting the tail boom to the main frame, then pull the tail boom backward. Pay
attention to the belt's elasticity. Fasten the screws back when the belt is adjusted.
