The DA-42 is a good aircraft in many respects however as Fuji says...its new and that is not always good. I've been hiring one for about a year and i've had a problem every time I've flown it! Engine failure, ECU failure, MFD failure, AHRS failure...the list goes on, that aside SE performance isnt all that bad when its light, bit of a b***h when its fully loaded though!
The aircraft that I hire has had no expense spared on it so it could be bad workmanship on the part of Diamond or the maintenance dept. or it could be the fact that its a new a/c and any problems have not been ironed out yet.
I would say though that when it works its an excellent bit of kit! As is the Seneca II although a bit more physical to fly than the 42.
