It's to do with how Ranwers modified the meshes. Instead of creating and importing new 3d meshes from 3DS Max, he used a hex-editor to change them. The FMB doesn't like that, hence the problems. The way I fixed the E-1 was to identify the meshes he had changed with the hex-editor and then make new ones in 3DS MAx to replace them.

That was relatively simple for aircraft like the E-1 which just needed a new canopy and mid-wing section. But for aircraft like the Cant which are totally edited meshes I don't think there'd be a fix aside from remaking the entire thing from scratch.
