    next is the SUU23 gun pod and centerline tank!

    I switched gears from MK84 to MK82. Again I split the model in pieces to limit the printed support required for the model. Here is the STL file. Let me know if you would like the cad drawings. These are to the same scale as the sparrow above.

    Looking great ! What is the FS number for the F-4 interior color? I know all the German & US Interior colors from WWII, but not the Phantom. Thanks!

    Here are the STL files for the AIM-7. These are scaled down for the length. Again I used 63' for full scaled Phantom that gave me 0.0807 X the full scale length. I don't like too much support on my prints so I sectioned them into 4 pieces with keyed plug / sockets for ease of assembly and to not be too long in the Z axis. So the only support they will require is inside the socket ends. Let me know what you think. If you would like my autocad drawings to mod or anything, Let me know.

    They are 11 5/8" long. A little short for scale, but the body diameter (3/4") is perfect.

    Even at 1/13 scale, my fins overlap some as well. These are from the Freewing F-14 ordnance set. I can live with it though.

Even though I scaled the missile close to the models scale ( about 11.5) , its "wingspan" goes past the centerline of the model significantly.

    So now I have to decide whether to scale down the entire missile ( to about 1:12.5 to make it work) or cheat something with the geometry on the fins.

    I can't find the actual length of the f-4d. I find the f-4e. It states its length @63 ft. I have been using that number to determine scale. 63'×12"=756" , 756"÷61.02=12.389, 1÷12.389=.08072. That is the number I have been using. So I scale the full scale down to this number.

    Thanks, guys. Just working on the next Freewing release.

    Bbaumer, you're finding the reality of how we scale our models --they're never 100%. We always adjust scale dimensions to achieve a believable degree of proportion. Wing thickness, intake size, etc all play a part in the influencing the final model. It's a good idea to draw based on 1:1 as a starting point, but ultimately, resizing parts against the actual model itself is required for a snug fit. Keep at it, though. It's looking good!

    This is for sure the coolest thread on the forum. Great work everyone, this is a lot of fun to keep up with.

    The sky really is the limit with this 3DP stuff.

    Maybe keep the current scale lengthwise and just scale down the width to just affect the fins? The missile body seems to be a perfect fit in the voids.

    I noticed I get 2 different scale numbers when using the planes length vs it's wingspan. 12.38 in one direction, 11.35 in the other. Personally I'll be rounding out my parts to 1/12, but like you are experiencing, certain things will need more changes to work.

    My canopies are propped up for static display. I fly with a stock canopy/cover.

    my bad, I was using the wrong length for the full scale Phantom. the scale I am calculating now is1/12.389381.

    The best part about modeling ordinance for the A-10 is there is a lot of overlap with the F-4. Here is an AN/ALQ-119 I made specifically for the hog, but can scale down and use on the phantom as well
