Just thought I would share some info I got from DroneDoctor here in the UK. They just did my repair following my goal post crash that was luckily just a recalibration of the gimbal. They mentiond there is a 6-8 week wait on parts from DJI at the moment & as a result  I didnt get my snapped sensor cover replaced (still fits fine its just cosmetic).

Food for thought if your gonna try any daring manoeuvres this month
