    Remember, too, you will want to change the airfoil for something more appropriate for the speeds and load intended, as well.

    I'm currently doing exactly that on my project. See my thread here

    Hey all, new here but hope I can contribute and maybe get some help. I have the Jurca 3/4 scale P-40 plans already, BUT,
    I'm thinking about having Jim Stewart (Stewart S-51) do the engineering for a all aluminum fuselage. I would also have the rest of it looked at as the project progresses. As for trying to scale, draw and build from the original factory drawings, the parts count would be daunting. I put a fair amount of research into options and the Jurca plans seemed to be the only viable way to build a scale P-40 with any real performance more than say the Loehle.

    Years ago I was at a local air show and froze in my tracks when going by a hanger! A P-40 fuselage on a stand. Looks funny. It was old skins from a restoration project that were put together. Come to find out some hot rod car guys who make fiberglass bodied tried to make a replica in fg, and that was the mold. I don’t think it went much farther. Especially if it was chopper gun glass. I’m constantly looking for the P-40 owned by Fed Ex. Came with buying the old Flying Tigers company. It had been on display in various museums but not now. All I can think is it’s sitting in the CEOs office. It has to be around here somewhere.

    I would be concerned about appropriate structural calcs and testing. Is the builder familiar with that end of airplane design, because that is really what he is proposing.

    Interesting. For a while it was not on display at Pearl. It’s in there with the jets so makes me wonder

    I often thought how easy it would be to take the Taylor mono and with some creative building make it look just like a P-40 or even a spitfire

    Dana, does the jurca P40 only have the wood fuselage like the ME109. I wonder if you could adapt the (MJ77) P51 metal fuselage to the P40.

    Not necessarily. According to the Incomplete Guide to Airfoil Usage, the root was NACA 2215 and the tip was 2209. These aren't sophisticated high speed airfoils or anything. It might be necessary to add a bit of wing twist or other dodge, since according to Profili the 2209 has a lower max CL at the lower Reynolds number the tip has to operate at. (I used 1,000,000 and 650,000, but a heavier or larger replica might have higher numbers.) According to the Incomplete Guide, the WAR replica used the 23015 and 23012. Something different might be advisable to lower stall speed somewhat for a Part 103 legal replica.

    Yes, the MJ77 structure drawings could be used for the engineering and just alter the mounting points for wing and tail wheel, ect. Here's where I diverge with typical thought. I have to go to the bother of making a metal skin, it's going to be a stressed skin structure and not have the extra fixturing, labor and all of the steel tube structure. That and I've not found anyone that has the drawings.

    Dana, I have a set of MJ77 plans for sale with the tubing frame option if you are interested. PM me if you are interested.
