On the servicing side, apart from the usual daily/weekly checks of levels etc., most items in the schedule are done on a lesser of miles/engine hours/time basis, which means you'll almost certainly meet the "yearly" criterion before anything else. There have been suggestions about modifying the rear engine bulkhead to allow access to the oil filters; if that's done then you'll only need to remove the pack for repairs.
I'm sure sharky will be along soon to give you a proper operator's perspective!
