Er .. Rob, the wingspan of your 1/72nd scale 'cruiser will be around 23 inches, and narrow in chord.
The He111 in 1/32nd scale will have a span of over 27 inches, and a thick, wide chord, bulky wing. The fuselage will also be big and bulky, with a length of over 20 inches, and around four inches in diameter!
For a twin engined model, that's big, bulky, and probably heavy, even though it's plastic!
