Hello, When flying today somehow my controller RHT button became detached possible can I reguest a RMA to have this repair.
How long does a repair take located in the United Kingdom. Thanks

Contact your local dealer first.  If its DJI go here and start a ticket for an RMA.

Had the same happen to me, returned the transmitter to the dealer (CVP in the UK) and within three weeks DJI had given me a new one.  Great service and CVP loaned me a transmitter while mine was away..  Looks like it may be a common fault.

Sadly you are not the only person with this issue. There have been other Posts noting the same issue.

Hi ,Strawberry
Sorry for that ! Please concact your local dealer for that  .
