The Litchi documentation does include a user’s guide which makes clear what functions are supported. A quick search of that documentation does not reveal any mention of IMU calibration. It would be impractical for Litchi to list functions that it does not support. Such a list would have to be updated whenever a feature was added to a DJI drone that Litchi does not (yet) support. Another user has compiled a list of functions for which the DJI app is still required. It may not be 100% complete but should be pretty close: > [@Do I need to have DJI Go4](https://forum.flylitchi.com/t/do-i-need-to-have-dji-go4/1834/2): > > You need the DJI App for: -Activating a new drone. -Firmare updates. -Unlocking No-Fly-Zones -Calibrating (if needed) the IMU. -(Re)Naming the drone. -Some MC settings. -Some obstacle avoidance settings. -Gain & Expo tuning. -Some Remote controller settings: -Stick Mode -5D button customization. -Remote controller calibration. -Remote controller linking. -Read the Sensors State. -Image transmission settings. -Aircraft battery settings. -Payload setting. -Beginner Mode. -… Per… > [@tlacombe](#): > > This is a required feature as my drone will not take off without the calibration being done.

Why is it that you need to re-calibrate the IMU before every flight? > [@tlacombe](#): > > Apparently there is another third party app that supports IMU calibration which tells me it is a part of the SDK. For curiosity sake, what is this other app that can calibrate the IMU? --- _[View the full topic](https://forum.flylitchi.com/t/imu-calibration/18827)._
