    Question Need wing mold for RC glider

    I am looking for someone to make the molds for RC Glider wings. This will be for multiple offs. I can get the CAD drawings for the wings. There will be a right and left wing in the 3' - 4' length each.

    Red face RC Glider wings

    Something that will be able to allow multiple wings to be pulled. I need something economical as this will be hobby/club project. May want to have fuselage mold made as well.

    Does your cad data have the airfoil curves?
    Do you need to develop 3-D contour model?
    Is it a NACA formula curve?
    Check this site:

    I am offering wing lofting experience and mold making experience.
    (former aerospace, complex wings or simple)

    Aluminum mold? multi-cavity? what material molded?

    Note: this can get very complex and costly.

    Red face RC Glider wings

    I am looking for the most economical mold type available. Airfoil is UIUC SD7032 with root of 8.5". Any idea what cost might be (rough idea)?

    Wild guess would be 4.5-7.0 Thou.
    80-120 hours, start to delivery.
    Anyone else ready to guess?
    This is an expensive hobby.

    How many parts do you need and what material do you want to make them out of?

    I'll kindly suggest this. Yer doin' it wrong.

    Instead of looking at a machined mold for a limited use, look into making your own mold out of glass with appropriate wood reinforcements.

    You need to make at least one "Master" to use to make the mold, then build your mold from there.

    A friend of mine was building small electric pylon racers in his basement with this method, and I have built, among other things, aircraft wheel pants and a couple sets of special purpose sinks (for alodine treating aircraft parts) using this method.

    It will bring the costs down to something that is not prohibitive. Mostly it's just about the same labor as building a model.

    Cheers

    wing moulds

    Hi I'm a long time out of serious model aircraft stuff, but still in touch with what's happening.
    Mike F( zone member,) built his own machine for ( mostly ) glider wing work, and the current build style seems to be pre-preg carbon over fully machined Rohacell cores. He's done cores for C/l Speed & T/R, F3B, Helicopter blades etc,
    and the core machining is quick enough that he can sell them without scaring the users.I know He's also machined female moulds for pressing the carbon skins.
    I'd go find the competitive F3B flyers, ask how they're getting stuff done. I can't imagine they're just marking time with old build methods.
    I always found fellow modellers ready to help and collaborate with tech.problems when I was competing.
    Hope you find the same,
    Regards,
    John
