The ultimate target of these designs was not to equip Tempest with Allison V-1710, which would be a step backward, but to a slicker engine, something a little narrower but longer.
I first considered Griffon, but it is too narrow IMO for this design. Now I am considering Wright Tornado; this is equally wide and 35 cm longer (5 mm in 1/72).
Would it need contra rotating props? IMO, no.
Please your comments. :thumbsup:
