Yes, WooKong can be flown without GPS in Atti mode. However, position hold will be affected while altitude hold is maintained using on-board barometer sensor.

WooKong controller does not require high power consumption. When flying Flybarless, power requirement from digital servos can be higher than Flybarred setup. We recommend using external BEC with minimum 7.5A power. Use of external power pack such as 2S Lipo is recommended for gasser and longer flight time.

WooKong configuration software supports servo frequency speed from 125 to 560Hz. Please make sure to obtain servo frequency response from the manufacturer.

Please make sure you have downloaded the “driver” from our website, and install the driver so that Windows system can recognize the hardware.

No, a minimum 7-Channel radio and receiver are required to operate WooKong.

Yes, during test flight you can use radio sub-trim or trim to adjust for leveling flight. We do recommend you to use software trim afterward and re-set all radio trims to zero value.

Your radio might be set to Fail-safe. Please go to “Tx Cali” screen, program (your tx) the mode switch channel using travel adjust and or trim to set the three position switch effecting “Manual”, “Atti” and “GPS Atti”.

No, once calibrated, re-calibration is only needed when the flying field is far from the location of last calibration (over 20 miles).

WooKong only supports Windows 32 bits Microsoft Windows XP, 7 and Vista.

No, we do not recommend flying the helicopter in rain, as water might get into GPS compass and controller causing electrical shortage.

Once setup, you don’t need your computer or laptop. In normal setup, it might require a handful of parameter changes.

Your local DJI dealers should be able to guide you through. Or, write to DJI headquarter, likely we can offer assistance via phone contact.

Make sure in auto mode “System Check” the swash movements (up/down) correspond to the correct direction in providing positive and negative pitch.

Make sure you have servo frequency response from the manufacturer. Often times, the frequency response is not released. Using lower frequency will reduce tail wag and servo temperature.
