FI or Carb?
I guess nobody has picked up on the fact that the "Carb Heat" on the G2 is "Automatic" and controlled by the EPM.
There are built in "self tests" and indications of system failures.
If you revert to "manual" or have any doubts you should select "HOT" whenever below 80% MLI.
Carb definitely starts a lot easier. FI has its own little foibles and is not the only answer.
With respect to FI - Lycoming would have to certify another engine as there is no equivalent to the current 360 model as used that is injected. It is not a case of just bolting an FI system on the existing engine.
A carburetor is lighter and cheaper to overhaul and or repair. USD 500.00 versus USD 5000.00.?
As to the zero G cuts - what were these people doing? If it was the competition the rotor probably would have departed as well.
The aircraft was developed personally by Bruno and first flew in 1992. I think his solution is a pretty good one.
Anybody ever experienced icing in a G2? Possibly not.
