XK X260 Instruction Manual - Fail Safe / Signal Loss

To active headless mode you have to press and hold down the headless button for 2 seconds. 

Once CF/Headless mode is active the transmitter will emit a constant beep to show it is in 

headless mode.

Once in headless mode no matter which way the quadcopter is pointing, forward will always be 

forward, backwards will always be backwards, left will always be left and right will always be right.

Fail Safe / Signal Loss

If the X260 loses connection with the transmitter, after 2-3 seconds the power to the motors will 

reduce and then cut to save the X260 from flying out of control. The LED’s on the X260 will also 

begin to flash.

Gyro/Accelerometer Calibration

If you experience any abnormal movements during flying you can recalibrate the X260’s gyro.

To recalibrate the X260 place the X260 on a level surface and connect the battery.

Make sure the throttle control stick is positioned downwards and then turn on the transmitter.

The Transmitter will make a constant beeping while it is binding to the X260. Once bound the 

transmitter will stop beeping and the X260 LED’s will change from flashing to solid to show the 

quadcopter is bound and ready to fly.

Hold both control sticks to the bottom left, the LED’s will all flash to show calibration is taking 

place, once the LED’s stop flashing you can move the throttle stick back to the lowest centre 

position and the right stick to the centre. The X260 is then recalibrated and ready to fly.

No response after the battery is 

connected to the Quadcopter

Motor does not respond to the

Unable to bind to the transmitter.

1. Battery is not charged.

2. Transmitter batteries are low

3. Poor battery connection

Quadcopter LiPo battery voltage 

is too low

Throttle trim has been 

accidentally knocked during 

flight

Repeat the power up sequence 

and rebind the Transmitter and 

Quadcopter

1. Make sure the battery is fully 

charged

2. Check and replace the 

transmitter batteries

3. Re-seat the battery to ensure 

a good battery connection

Fully charge the battery or 

replace with a fully charged 

battery

Check the throttle trim is in the 

centre or slightly below
