Inspire 1 Grounded By Faults

In a update to the ongoing saga with DJI’s new Inspire quadcopter that we summarised here, DJI has e-mailed dealers (confirmed by a number of dealers on both Facebook & Twitter this morning) to warn users not to fly until the new firmware is available to address IMU miscalibration along with prop locks, the warning has been posted as follows:


A required update is now available for your DJI Inspire 1. This update will fix an issue that some users may experience with their system’s IMU becoming uncalibrated during shipment. Please download the firmware package from the official DJI website and update your aircraft’s firmware immediately. If you have not yet flown your Inspire 1, please download and update the firmware before your first flight.

If you have questions regarding this update or any other concerns about your Inspire 1, please contact us at


The Inspire 1’s propellers may come off during flight if they are not correctly mounted 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 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.

The release note for the next firmware is here.

An admin of the UK Inspire group made the valid observation “I guess if DJI actually sent Inspires to knowledgeable Beta testers instead of Celebrities and DJs they would of known these problems well before release.”

In further embarrassment for DJI, the 1st Inspire to be repaired having crashed just over a week ago, crashed again as confirmed by the owner on Facebook.  Gizmodo and the UK’s Daily Mail newspaper have been amongst those now reporting on the IMU bug.
