Planebuilder62 Posted February 23, 2020 Share Posted February 23, 2020 Hi there Is it possible to cross kit a Brengun 1/72 Mustang Mk1 with something else and a Spitfire 4 blade propeller to come up with a Mustang X? I know there is a High Planes complete kit for this but I have built some of their kits and found it best to use the bare minimum from their set. regards Toby Link to comment Share on other sites More sharing options...
gingerbob Posted February 23, 2020 Share Posted February 23, 2020 (edited) I keep asking myself the same basic question, but in 48th. The first thing I would do would be see how a Spit IX top cowl looked, and take it from there. A 2-stage Mossie intake might be adapted? (Edit: neither idea seems particularly good, though there might yet be room for a Spit cowl top...) Hoping to come up with some better answers via this thread! bob Edited February 25, 2020 by gingerbob Link to comment Share on other sites More sharing options...
Max Headroom Posted February 23, 2020 Share Posted February 23, 2020 Depends whether you want to model a Rolls Royce re-engined example (Mustang X) which had a chin radiator, https://en.m.wikipedia.org/wiki/Rolls-Royce_Mustang_Mk.X#/media/File%3AMustang_X.jpg or the North American XP-51B which had a deeper ventral intake. https://www.worldwarphotos.info/gallery/usa/aircrafts-2-3/p-51/xp-51b-ex-mk-ia-raf/ Trevor 1 Link to comment Share on other sites More sharing options...

72modeler Posted February 23, 2020 Share Posted February 23, 2020 It would be a very distinctive Mustang, that's for sure! See the attached American Air Museum photo of AM121 for details. Looks like a Spitfire Mk Rotol prop and spinner. The upper cowling contours look to be the same as on the Allison Mustang, and you can use Spitfire fishtail exhaust stacks, from the look of the photo. I'm guessing the deeper chin intake feeds the carburetor and intercooler- you can see the exhaust gills for the hot intercooler air on the fuselage above the wing root. As for that chin intake and lower cowling, maybe a P-40E-N intake reworked and mated to a new wood or plasticard lower cowling. Good luck!

It explains all Mustang to Merlin iterations. There were several Mustang X with different cowling designs. http://www.hyperscale.com/2013/reviews/books/valiantwingspreviewbg_10.htm Link to comment Share on other sites More sharing options...
brewerjerry Posted February 23, 2020 Share Posted February 23, 2020 (edited) Hi I thought of doing one many years ago, but i never got around to it but i think i was thinking of using a merlin whitley or merlin wellington engine nacelle as a starting point p.s. and seem to recall having to use an allison engine mustang kit as apposed to a merlin engined kit something to do with the main wing position ? cheers jerry Edited February 23, 2020 by brewerjerry Link to comment Share on other sites More sharing options...
Jamie @ Sovereign Hobbies Posted February 23, 2020 Share Posted February 23, 2020 I think besides borrowing the spinner, propeller and fishtail exhausts it would be easier, faster and cheaper just scratchbuilding the firewall forward rather than destroying another kit to steal its front end which still looks nothing like the Mustang's beyond a superficial layout similarity. Just my 2p. I'd be starting with a pair of plasticard side profiles tacked to the kit fuselage halves and a pair of half-bosses for the spinner then build up from there. 1 Link to comment Share on other sites More sharing options...
JasonC Posted February 23, 2020 Share Posted February 23, 2020 The publication you'll be wanting is the Rolls-Royce Heritage Trust Historical Series No. 9, "Rolls-Royce and the Mustang". It gives probably the most complete account anywhere of the various Mustang X conversions (of which there were at least five). In chronological order, the serial numbers were: AL975/G, AM208, AM203, AL963 & AM121. https://www.amazon.co.uk/Rolls-Royce-Mustang-Rolls-Heritage-Historical/dp/0951171003 Despite all being called 'Mustang X', there were numerous detail differences both between airframes, and on each airframe over time. Notably, AL963 (eventually) had a much lower profile nose intake achieved by re-positioning the intercooler, and some were fitted with a broader chord fin (as opposed to a fillet). The latter mod is visible on the port side photo of AM121 above, in posts #4 & #6. I also agree with Jamie that the inlets bear only a passing resemblance to anything 'out of the box' from another kit (bar something esoteric), and that the best bet is likely a scratchbuild. regards, Jason 1 1 Link to comment Share on other sites More sharing options...

There were several Mustang X with different cowling designs. http://www.hyperscale.com/2013/reviews/books/valiantwingspreviewbg_10.htm I think a P-40F intake would be too big and too deep, as it had to contain the coolant and oil radiator, and carburetor air intake. I was thinking, after I posted, that if the op has a Hasegawa or Hobbyboss P-38J in his spares bin, the cross section of the chin intake should be pretty close to the right size, and would also have that same slab-sided contour. Not one I would want to do- distinctive, yes; attractive, no! Mike Link to comment Share on other sites More sharing options...
FinnAndersen Posted February 23, 2020 Share Posted February 23, 2020 I built a MK X with a HighPlane nose and a Hasegawa fuselage. This was clearly wrong as the Allison Mustang had a shallower fuselage than a Merlin engined. I do have some spare X's lying around, so if you want one, please ask. I contemplated doing a brengun/highplane hybrid, but the brengun fuselage is too deep and that has stalled the project for now. /Finn 1 Link to comment Share on other sites More sharing options...
Mr T Posted February 23, 2020 Share Posted February 23, 2020 I built the High Planes kit a number of years ago and put it on here, although I am struggling to find it. I know I used the basic kit and then added bits from a Revell kit as they were much better defined than the kit offerings. 1 Link to comment Share on other sites More sharing options...

FinnAndersen Posted February 26, 2020 Share Posted February 26, 2020 This is my HighPlane/Hasegawa hybrid. I now realise that it was made a while ago and has suffered some damage as it's missing the arial mast and tailwheel doors. Now I'm very tempted to try again, especially as I now realise that I did not correct the wing kinks. /Finn 6 Link to comment Share on other sites More sharing options...

Planebuilder62 Posted June 3, 2023 Author Share Posted June 3, 2023 To resurect this this thread, on second thoughts could an Arma Hobby P-51B have its nose cut off and turned into a Merlin Mustang Prototype? Photo´s of the Brengun P-51A seem to skow an exagerated nose up attitude, maybe its undercarriage legs are too long. Regards Toby Link to comment Share on other sites More sharing options...
Max Headroom Posted June 4, 2023 Share Posted June 4, 2023 No. Production Merlin Mustangs had a noticeably deeper fuselage. Others will soon arrive to give measurements! Trevor Link to comment Share on other sites More sharing options...

Compare the two drawings (and definitely visit the site!) Basically the wing was dropped 2-3 inches (forget exactly) 1 Link to comment Share on other sites More sharing options...
