    If machine tends to drift perform accelerometer calibration on a flat level surface.

    Tap on calibration on St 16 and choose accelerometer..... for more info watch this video:

    I agree there is nothing in the manual regarding how to calibrate the accelerometer. I had to post the same question as you. Regarding frequency. I only do it if I notice my birds (phantom, Q500, or H) is drifting around or I do a firmware upgrade on the bird...

    When the video has played for 3.16 minutes you can see where/what to tap for all calibration options ;-)

    Tap the tab and it will tell you what to do my friend! I understand Yuneec is not too informative on many things of yet, but just tap it and it will probably just tell you to set on a level surface and do not move, then tap ok, and let it do it's thing, I personally have not done the ACC Cali, as my bird fly's smooth as a babies bottom, Thank God !

    ACCELEROMETER C ALIBRATION

    STEP 1) Place the TYPHOON H on a level and stable surface. Switch on
    the ST16 Ground Station and the aircraft and wait till the RC and WiFi
    connected.

    STEP 2) Make sure the FLIGHT MODE switch is in the middle position.
    Tap the GPS Calibration but ton, and choose 'ACCELEROMETER'.

    STPE 3) Keep the aircraft stable during the calibration process. During
    calibration, the main led will blink red, green and blue slowly at first
    and rapidly afterwards. If calibration succeed. The copter will restart
    automatically. You will recognize the this when you hear the raising
    tone.

    NOTICE: You must do the acceler ometer calibration in no-wind condition.
    IMPORTANT NOTE: If calibration has failed, the Main LED Status
    Indicator will be solid white and you must repeat the calibration
    process. If the calibration continues to fail, either the site of calibration
    is unsuitable or the accelerometer is defective. Refer to your
    Yuneec service center.

    just leave it on the ground ?

    No, leave it on the ground or whatever flat and level place you have it sitting...

    Don't know if it has already been mentioned, but the SD card included with the H has several "How To" videos on it. Calibrations are among them.

    On a level table, grounds are not too level!, with props off

    you know step 3 that Yuneec mentioned above "Keep the aircraft stable during the calibration process."

    does not sound like leave the aircraft on the ground . since it was already on the ground in step 1

    maybe there verbiage is whats causing so many crashes . will wait for Yuneec's comment on the matter .

    Agreed, its not clear, I had the same thought as you. But one of my other posts somewhere, Yuneec says the Accelerometer calibration method is the same for both the "H" and Q500. The Q500 has it sitting in one place. I did mine sitting "still" and it "appears" to be working fine...

    Depends, I use a carpenter's level with the bubble to ensure where I do my Accelerometer calibration, the surface and the bird are actually level. I would recommend even if you do it on a table you use a carpenter's level to ensure the table itself is level, I've seen tables that leaned in one direction or another. Using a level will ensure no matter the surface, your bird is level...

    I will correct my list to add level table, not ground!

    Strange...in the Typhoon Manual V1.3 it clearly states that the calibration should be done taking off from a level surface and hovering in the AIR! So confused....

    ACCELEROMETER CALIBRATION

    STEP 1) Place the TYPHOON H on a level and stable surface. Switch on the ST16 Ground Station and the aircraft and wait till the RC and WiFi connected.
    STEP 2) Make sure the FLIGHT MODE switch is in the middle position. Tap the GPS Calibration button, switch off GPS and choose 'ACCELER- OMETER'.

    STPE 3) When the main LED indicator blinks red , green and blue slowly, hold the motor start/stop button to start the motor, then the main LED indicator will blink red, green and blue rapidly. Push the throttle joystick gently above the middle position to take off the aircraft. Meanwhile, keep the aircraft hovering manually until the main LED indicator blinks red, green and blue slowly again.

    STEP 4) Landing the aircraft and hold the motor start/stop button to stop the motors, the copter will restart automatically. You will recog- nize the this when you hear the raising tone.
    NOTICE: You must do the accelerometer calibration in no-wind condition.
