I'm paying £347 inc VAT, but you pay based on a calculated engine time, which seems to involve adding 0.1 to the Datcon for each flight. Makes it like an R22 whiere the Datcon runs on the engine time rather than collective.
If you have short flights, that makes it a bit more expensive (you pay 0.6 hrs for 0.5 hrs in the air), but for a 1 hour flight in the air, you'd be paying £382.
