Thanks for your reply.
And a radar ART2000 with an MX200 (that goes in place of the MX20)...?
My mechanic quoted me a very high amount of hours and I’m trying to understand how we get to 126 hrs of labour for this, installing Gaminjectors, removing a prop to change an alternator belt, putting a new prop governor (engines are already de-cowled), say a day of setting/up/troubleshooting/couple of flights.
Maybe he’s right, I’d just like to have another opinion...
