Oh wow....shots are wonderful...

That aircraft must be in all configurations then.
-floats
-amphibious floats
-wheels
-wheel/skis
-skis
Chuck will the skis retract for just wheel landings and are there different ski settings or just up and down?
If so then all aircraft developers should take note on that is the way to do it.
If the aircraft can be used in different configurations then that is the way to develop it...

Different ski settings would be much more realistic as there are reasons for using different ski settings when flying real world aircraft.
Oh I posted a question in the other Antarctica post asking about the Twotter configurations before I read this one.
Sorry Chuck...

Who makes this aircraft or is it Freeware?
