BB56 & Wild Argentina Pucara Project

  1. Well if all goes as planned this is what it should look like. I am going to opt with big air and somewhat efficient motors , couple new Turnigy 2826/10 1400kv motors that were meant for combat planes but I do have 4 of those fully loaded so I have spares. ;)

    I think you might need a larger Elevator / Tail fin? but looks very impressive

  7. The elevator control surface is pretty large so I don't think there will be any issues with it, (hopefully :) )

    The horizontal stabilizer looks small on the drawing. If it is too small there will be a pitch control problem like not enough damping.
    We can see what it looks like when assembled and if needed, we could increase the H-stab area before it is all glued up.
    On old school models which had rudder + elevator only controls it was customary to enlarge the H stab to make the model more docile.

  10. Some parts cut out. Built the spar, 6mm cf strip in the center section overlapping the dihedral point, outside of the spars 4 pieces of plywood to overlap the dihedral point . In the wing in the outer section there will be a 3mm cf strip just underneath the rear spar. Hopefully it should give me a good strong wing.

    Dry fitted the battery tray and formers all together, found a couple glitches but went together like it was suppose to.

    Check the rear lower formers 3 and 4.

  14. Well it is almost all cut out, just a little more on the fuse but I think that will wait until tomorrow as the back isn't liking me anymore. ;)

    I know that feeling:)
    I need to fix some extensions on my building bench legs so I don`t have to bend over so much.

    Nice work guys!
    The Pucara is a strange plane... the first time I saw in a air show at the distance impress me a lot because looks like a fighter jet but when I saw its motors was a little disappointing ... on air it was a little slow and nothing “acrobatic “ for a COIN airplane (compared with Brazilian Tucano or Super Tucano). Anyway looks awesome and magestic in air and twin turboprops always sound nice.
    Your model looks awesome and put a good pair of motors will not be too scale performance (fortunately !) but will make a justice for a good looking plane.

    Thanks Rodrigo, you are right, from the side it looks like a jet but from plan view the wings look more like a ww2 fighter.
    We are hoping it will make a good flyer and I`m sure being able to fly slowly would be a good thing for a COIN aircraft.
    The British evaluated a captured Pucara and they said it had disappointing performance, but we don`t care about that as we are not going to war with it:). I`m sure me and Jeff will get the depron version to fly very well.
    I was reading the stats and it has two 950hp turbo props and can only do 315 mph. Where is all that power going??:D
    The Tucano is a very capable plane after all 18 counties use it, but I wanted a twin :)

    I may have misunderestimated the size of this model. Don`t worry I`ll get a bigger car:D The wing span is only a few inches longer than the fuselage which is only dry fitted at this point.
    That`s a 1 meter ruler laying by the side of the fuse.
