I recently went out of warranty too, so guess this is coming out of my pocket. The gimbal is working and I have perfectly fine propellors, but the IMU is not calibrating and the accelerometer is saying that it is not right or something like that. Anyone got any solutions, this is my first crash after a year and a half, super dissapointed.
It's most likely an main controller issue, it would be best to send it in to DJI for service. They do provide invoices before initiating any repairs so you can choose whether to move forward.
Balloons and similar objects that float about are to be kept away from ... they tend to get drawn into props if not careful ..............
We do a lot of Limbo and streamer flying at shows with our club ... guess what !!
We did try balloons once ... once was enough ! Only time they are OK is when tied to a stick !!
My sympathy ... hope it all gets fixed soon.
Note : I noticed the focus went all fuzzy at times on the video - was that your processing of video or auto-focus of camera not knowing what to lock onto ?
