I am working on the Penelope's gunpla and finished building the Odysseus Gundam and am working on the FF unit. I just noticed the FF unit has two cameras built into the frame which is absent from the original design of the novel version of the FF unit. at 26 meters the Odysseus Gundam is really the largest non-Psyco Gundam unit ever built and the FF unit makes the thing too big to really fit on the catapult of an MS carrier. now remember the Penelope is a Newtype use MS so it's installed with a psycomu system of some sort (personally I feel its a psycoframe equipped unit.) and there is also no evidence of a secondary cockpit for the FF unit. so I think the FF and Argos units are actually the largest funnel/bits ever built. The Argos unit is teased at in the gunpla manual.
