Reely X-140 RTF Operating Instructions Manual page 35

• Manual trim D buttons (12): These buttons will correct unintentional lateral displacement of the quadrocopter by
pressing buttons Trim D in the opposite direction to the sense that moves in an involuntary way until it is corrected.
It is advisable to make the final trim adjustment when the craft is airborne.
Automatic trim/reset
The quadrocopter is equipped with an auto-trim system whereby its initial settings can be restored, allowing the
aircraft to fly in an accurate and level manner. When do you have to use this function?
• If the quadrocopter has taken an impact and as a result its gyroscope/electronic stabilizer is off-kilter.
• If you have transported the quadrocopter from one place to another.
• If the quadrocopter does not maintain its fixed position when hovering.
Place the quadrocopter on a flat surface during automatic trim/reset.
• As you can see, when both joysticks are moved to the reset position (as indicated by arrow direction in illustration
Fig. 5) the lights on the quadrocopter will start to flash rapidly, which means that the reset process is being carried
out.
• Once 10 seconds have elapsed, return both joysticks to their initial position, at that time the lights on the
quadrocopter will stop flashing, which means that the reset has completed successfully.
