That's too bad ! The pilot and machine guns look great ! What scale is this kit ?
You might be able to use some aluminum tubing to save the short shot struts. A company called "K & S tubing" makes materials in different sizes that might just work for you...
Another possibility would be to take some plastic sprue and rebuild the end that's missing. Biplanes can be tricky...Hope this helps.
Thanks for starting the build thread and welcome aboard !
