    And, FWIW, the aoi of the A-plane is 1.1*

    Also FWIW a second set of eyes agrees with your math. ...if it's a 54" chord.

    FWIW = For What It's Worth

    AOI = Angle of Incidence

    For the minimax wing to be at the same height as the affordaplane I have to make the attatch point 3 1/2 " above the tube.
    I'm having a hard time doing that without adding alot of weight. Would it make any difference if the mm wing was three inches lower. I think there is still plenty of head room.

    You got me interested in the affordaplane! Can you post some pictures of your fuselage.Is it per the plans?
    More than a few are flying.I think it is catching on.

    If you're happy with the head room I don't see why it would be a problem. But I think you could raise them 2" without adding much weight or hassle.

    I think the Stewart Headwind wings would work very well on the Affordaplane.Thay are much easier to build than the minimax wings if someone decides to go from scratch.

    I would just build the whole Stewart Headwind as it's at least 10x better than the AP

    Do we have to go through this crap again? It's apples and oranges. The Headwind is also 10x more complicated and more expensive to build. Old fat guys don't like the yoga contortions you need to do to get into them. People who don't want to do any welding wouldn't want to build one. The spars for a set of Headwind wings cost almost as much as the fuselage of an AP. etc. etc.

    fuselage/engine weight distributions probably are different.....be very careful as to where you mount the wing and doing your weight and balance calculations.

    The LG seems a bit different.Looks like its based on the airbike LG.Looks good otherwise.
    I think it should be a very quickbuilding aircraft.
    With minimax wing it should have similiar flying qualities.I hope.Not that the affordaplane wing is any less,though.

    I got the idea of the landing gear from a picture of a challenger. I have to make another pair of brackets that attatches the legs. Those are a little off.
    If anyone needs a pair of wheels and tires, I'm going to sell those on the plane.
    I agree.

    Not much of a drawing but if you can make sense out of it, tell me if making the gussets as large as this is overkill. The reason they are so much higher than the original AF is because the MM wing attatch straps are at the very top of the spar. Thanks Lee

    Looks good.The cross tube for the strut attach may have to go back a bit to stay inline with the front spar.

    Lee, could you move the attach straps down, to the lower part of the spar?
