Hallo Lothar, hier der Hersteller zu diesem Thema:
„
The F3G fuselage is slimmer behind the wing and shorter in front than the hobby fuselage. The fuselage is not squarer it is based on the same base in the front and the fuselage for the F3F in the rear.
If you will be using a motor with a gearbox (28mm diameter ) we recommend a fuselage sport.
It seems to us that the flight characteristics are better with this fuselage.
