    DB601 powered Hurricane!

    In 1941, a “Hariken” was modified with a DB-601 A engine

    The “Hariken” was the name for the Hawker Hurricane in Yugoslavia. The kingdom had bought 12 Mk.I’s in 1940, and a license to manufacture further aircraft locally, to be equipped with imported Merlin engines. However world events made the supply of Merlin engines for export very problematic.

    The Germans were asked if Merlins could be available from war booty in France and Belgium, but none were bought.

    And so the next proposition was to install a Daimler Benz DB 601 A in a Hurricane, as this engine was in stock for the Me 109Ea-3 at VVKJ. With this modification it was deemed logic to give the type a new designation, and it became the L.V.T.-1, meaning L - lovacki (fighter), V - vazduhoplov (airplane), T –prekonstrusian (redesigned) number one.
    It turned out to be very well liked by its pilots, and even took part in forcing a Me110 down on April 1st 1941, six days before the German invasion of Yugoslavia. The plane were engaged in battle on the first days of the war, and were seen with smoke coming from it. Sources do not agree whether it crashed or made a landing, but it disappears from history after that.

    To my knowledge no kits exists in 1/48 of this plane, even though Omega has a resin kit in 1/72 for those preferring that scale.

    I have been gathering some parts to use with help from fellow iModelers, stay tuned for an update soon

    This is going to be an amazing conversion, Erik @airbum
    Looking forward to how it will look like in the end.

    Gonna be interesting indeed @johnb and @fiveten.

    Comparing notes. . . or rather, noses

    In order to see what to expect I broke out a few other kits.

    No photos are known to exist, so all will be speculation, except that scetches has survived, and it is known that it was a fabric-covered Mk.I with the early non-armoured windshield and five-spoked wheels. To the best of my knowledge the centerline will have to be 11,4 cm below the RR engine plane, roughly 2,4 mm In 1/48 scale.

    How would the nose have looked compared to a Hurricane Mk.I then? Well, fortunately this engine was manufactured by other nations, and their planes may be giving us an idea.
    First, we have a few Italian planes


    quite a different nose.

    And looking at Japanese offerings


    sort of gives us the same general idea.

    As for the kit chosen for the conversion, John B was so kind to get me a Hasegawa Mk.1, in the shape of a rebox by Hobby2000. The old classic airframes kit is very expensive when they pop up on auction sites, and besides the old Hasegawa kit is with separate fuselage and engine, making it ideal for this.

    Now, the classic is with the correct fabric-wing, and Hasegawa is a metal-wing. I found a conversion for the wing for this kit in Canada. A few years back my good friend and fellow iModeler Klavs (@klavs1972) gave me a Hurricane book, and I have been plowing through that one in preparation for this build. A few pictures of the kit, conversion and book.




    and now it is off to the workbench!

    I have to figure out how to make the surgery, will it be some scratchbuilt re-shaping of the kit-nose, or will I need to sacrifice one of the other kits to use the nose from one of these?

    Very interesting subject, Erik @airbum. Looks like you have some work ahead of you. I will be following along.

    Glad I was able to help you, Erik @airbum
    Quite some surgery on the way.

    Welcome aboard @eb801. I shall be happily chipping away in a few hours time @fiveten and @johnb!

    Card.

    A simple card profile made to check alignment etc.
    I decided to use the Ki.61 as a template for locating the engine. First the fuselage and nose were dry-fitted to get a visual reference.

    Then the spare clear fuselage from the Ki.61 was used to check the propshaft location against the hurricane parts.



    and the panels checked for exhaust etc.

    Then a cardboard profile were made and the kit-nose cut off along the panelline



    All in all it looks like it is doable. There will be an issue with the exhausts and intake for the air, and some online drawings make guesses on how it might have looked. Considering it took 3 weeks to install the engine and make testflights, my guess is that it had minimum changes to the hurricane cowling. The prototype Hurricane had a panel under the exhaust that went from the nose to the firewall, whereas production examples had two panels, the one aft covering the area including the firewall, so on an operational plane the firewall is actually behind the middle of that panel. The exhausts on a DB engine will be the deciding factor!

    Let me hear your ideas too – nothing is fixed yet, but I hope to get moving later today!

    I think your approach has most chances to render the real thing, however it might have looked like, my friend @airbum!
    Looking forward to this mos interesting conversion!

    Your current approach looks like to have the best chance of succes, Erik @airbum
    Incredible to see the difference in height with the original nose.

    I am really looking forward to your conversion, Eric (@airbum). I don't think I have ever seen photos or diagrams of this plane at all. I think the templates you have made show that the conversion will make a plane that looks correct.

    Another exquisite project my friend! And surely another DB engine pouring high octanes 😉 @airbum
    To my skills this would be a daunting challenge, and probably a sure fail, but in your capable hands it’s already a joyride

    Yes. An “exquisite project“ is the word. Erik @airbum, you are a bonafide plastic surgeon. Your research is scholarly.

    Thank you for all the positive vibes gentlemen. A small update on this mornings progress @fiveten, @johnb, @gblair, @holzhamer and @eb801.

    Office dryfit.

    I painted and assembled the major parts of the cockpit this morning

    I had to sand a little to make it fit, but nothing major so far.



    I am certain this kit has had its innards revealed a lot of times, so I shall not go into details.

    Suffice to say I did thin the armourplate and seatback, all else is OOB


    Now the small parts will be added and then I will close the fuselage.

    with the fuselage assembled next, it will be left for a few days to cure, and then I shall commence some scratchbuild on the nose – or perhaps fit the wings? Tune in again later to check.

    Nice progress, Erik @airbum
    Good decision on thinning that armour plate, it does look much more like a real one this way.
