Narses2 and darkmaster---thanks.
Though it ostensibly will be a "Henley", the major fuselage components will be from the Revell Tempest (Mk V, stretched), that has enough constant-diameter fuselage for two places. The chin radiator will be enlarged (a la Tempest), and twin rows of exhausts will sprout on the sides (like the Hawker Tornado with the Vulture engine--love that look). The engine will be the 24-cyl *AIR-cooled* inline "Exe" engine that was supposed to go on various FAA aircraft, but didn't (don't know why--the Exe engine had much promise, and was installed and tested on a Battle). I have to have some air outlets---will either go with cowl flaps like a radial, or perforated plates like the Mustang. I will put on the distinctive Henley tail, and attach some Hurricane outer wing panels to the (Heller) Tempest V wings for the longer wingspan and rounded tips characteristic of the Henley. I at first wanted "car door" entry typical of the early Typhoons, but have reconsidered. MAYBE the pilot will have that.
PS--at one point Hawker made a Defiant-like turret fighter---the "Hotspur", and my Henley will be like a combo of the Henley and smaller Hotspur. The rear turret will have only two MG's, over-and-under style, so will LOOK like the four-gun Hotspur from the side. I had considered the moniker "Hotspurious" for my concoction, in keeping with tongue-in-cheek names for obvious whiffs, but I think I will keep the more "serious" Henley name.
