What is the advertisement about? A non flying model?
The Tunnan - I can't imagine that thing doing any aerobatics- loops, rolls except for - BARREL ROLLS - sorry I could not resist. With lots of wing area should have handled nicely, most early jets have big wings.
Speaking of cartoons - have you seen the cartoon Mig 15 and Cartoon Sabre - they use a large prop inside an even larger fuselage :
So maybe a pusher model as some have suggested would be a better bet. Something like a Vampire where the centre of thrust if there is such a thing is closer to the one in the real thing - somehow that seems important.
