Pre-Flight Calibration

Quadcopter/Remote Link

Before flying, the quadcopter and the remote must be linked together, and the gyroscopes on
the quadcopter must be allowed to calibrate to ensure smooth and level flight.
Begin with the quadcopter and remote powered off.
Step 1 - Power ON & Connect
Connect the battery to the quadcopter, place the quadcopter on a flat surface, and turn on the
remote. This will calibrate the gyroscopes in the quadcopter and connect it to the remote.
YOU MUST PERFORM THIS ACTION QUICKLY FOR IT TO TAKE EFFECT.
When the receiver light at the front of the styrofoam body begins slowly blinking red and blue,
and the Power/Status indicator on the remote is red, the quadcopter and remote are successfully
calibrated and linked.

Step 2 - Take Off

Add light throttle until the quadcopter is in the air. If there are any problems, perform these steps
again until a stable hover is achieved. If there are no problems, you may start flying at will.
•  Use Left Control Stick and add
light throttle.
10
Attempt a stable hover, low to the ground.
Trim Adjustment
Countering Drift & Setting Trim
Even after the quadcopter is calibrated, it may show a tendency to drift while airborne. Adjusting
the trim will counter this effect and allow the unit to hover in place. Adjust the trim while flying
as controlled and low to the ground as possible.
Remember, the red propeller blades indicate the front of the quadcopter.
If the trim adjustments do not seem to be helping, or seem to be making the problem worse,
press the Reset button to the right of the Left Control Stick, to reset the trim to factory default
settings and try again.
Drift Type
Quadcopter yaws/spins left or right.
