DJI Inspire 1 crashes – DJI acknowledge IMU “bug” – Firmware update available now.

Firmware update is released: Download here Inspire 1 Firmware v1.2.0.16

2015.1.15
Overview:
1. All-in-One Firmware version updated to: v1.2.0.16
Major Updates:
1. Enhanced self-check when aircraft is powered on.
2. Optimized IMU calibration process.
3. Raised the electro-magnetic interference standard for compass calibration.
4. Optimized aircraft yawing motions.
5. Auto-takeoff altitude set to 1.2 meters (3.9 feet)
6. Aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 20
meters (65 feet) radius of the Home Point.
Notices:
 Update the firmware to the latest version, otherwise you may not be able to start the motors. If you
are unable to takeoff after updating, perform an Advanced IMU Calibration. This is found in the DJI
Pilot app under MC Settings -> Advanced Settings -> Sensors -> Calibrate -> Advanced.
 Re-link the remote controller to the aircraft if the connection is lost after the firmware update.
 After the update, the aircraft must be powered on and carry out its self-check procedure on a flat,
stable surface. Do not perform the self-check on moving surfaces (such as on the moving vehicles).
 The Inspire 1’s propellers may come off during flight if they are not correctly hand tightened and
environmental factors (including sand, heavy dust, or high winds) cause the motors to stop or slow
down suddenly.
To prevent this, DJI is offering free Propeller Locks to all current Inspire 1 customers. If you ordered
your Inspire 1 from the DJI Online Store, they will automatically be shipped to you. If you purchased
your Inspire 1 at an authorized DJI dealer, you can collect them there. These Propeller Locks will
become available next week, and DJI recommends that you do not attempt flying your Inspire 1
before receiving and attaching the Propeller Locks. Future customers can get Propeller Locks from
the DJI Online Store or at a local authorized dealer.

After footage of Inspire 1’s crashing out after takeoff has been circulating for a couple of days, DJI has officially announced an IMU bug – here’s what it is and what to watch out for.

There is a firmware fix coming, but until it arrives pay close attention to your IMU MOD values in the app and recalibrate if necessary before flight. Original announcement on RCGroups: http://www.rcgroups.com/forums/showpo…
