I just got my 85 back. There have been a couple of updates. If yours has not been back at all, I would say you need to call DA! I have #25?something, I sent mine in for a hub update when it was annouced, I was ready to maiden her last months and called to order another engine and was told there had been several updates to send it in again. There was a nice list of stuff they did! It is a hassle but well worth it compared to having problems in the air!!
