My crashed P4 was shipped, inspected, repaired and returned in 18 days. 12 days were just for shipping. Here's the email they sent to me with my RMA:
"Note: Failure to complete any step below may cause delays in your repair, and could require our logistics team to ship your product back without repair service provided.
1. Please fill out and print the Customer Information Sheet attached to this email/ticket. This is required for every RMA.
2. Please include a copy of your proof of purchase. Not including your proof of purchase will automatically categorize your repair as Non-Warrantied and you will be invoiced after analysis. Please keep your original proof of purchase for your records.
3. Please review the warranty terms for your product to see if you should expect an invoice or may potentially be covered by our manufacturer’s warranty:

4. Do not ship swollen/punctured/visibly damaged batteries. If you do ship batteries in this condition, we are required to recycle them and cannot ship them back to you. If your battery was damaged in a crash and you would like to be considered for warranty replacement of the battery, you will need to provide proof of purchase and pictures of the damage and serial number(s) of each battery affected in the package you ship to us.
5.
Please do not include any product accessories, such as batteries, propellers, chargers, tuning stands, micro SD cards, cables etc. If you choose to send in any of these items, you acknowledge that DJI is not liable for any of these products.
6. Please do not include any non-DJI equipment, such as aircraft accessories, hard carrying cases, SD cards, and third-party transmitters. If you choose to send in any of these items, you acknowledge that DJI is not liable for any of these products and that we are unable to test your DJI products with any third-party products.
7. Pack your equipment safely. Include protection such as bubble wrap and packing peanuts. Keep in mind that any product shipped just in the on-shelf packaging (i.e. white Phantom box) is not acceptable and will automatically qualify it for invoiced repair. You can always place the product box or case in a cardboard box, this is acceptable.
Inspire 1 is the exception to rule 6, please do ship it in its original hard case, packed safely inside of a cardboard box.
