Hi scoots just had an annual done on my Raven II. It cost about £2,500 plus vat and they also scratched the tailboom! My wheels were missing and being used to transport another heli when I went to collect it. Personally think the whole maintenance thing in the uk is crap with this "fixed price servicing". Purchased my heli in Belgium and the main dealer there simply charged 48 euros per hour for the work. Even if that was pounds I'd be happy but trust me you aint going to change it. If your machine came back as bad as you say then I wouldn't pay the full amount and get it done else where in the future. Sorry to hear about your troubles.
