So for the G4, is a 5 seater with a turbine engine using the Cabri design philosophy doable? The G2 beats the R22 in lots of ways, however the R44 has fewer of the drawbacks of the R22. So a 4 seater piston isn't the step up from the 44 than the G2 is over the 22?
A competitor for the R66 though could be interesting.
