I think there is an element of rose tints here.....
The G2 is a wonderful machine and much more forgiving to the average PPL. Reliability wise it needs to be kept in a hangar otherwise it suffers electrical gremlins as befell the initial machine at Leicester, and even when in a hangar once it has a few hours under its belt you'll likely fly with something showing as failed - EGT sensor, etc. The DI is utter junk and is £360 p/h with instructor and VAT common now a few more machines are out there?
