Import it and edit the settings and then export it again is one option.
The other option, if you are good with a hex editor, is to look for w3d_file.h and parse out the file, editing the "Flags" field of the CHUNK_MESH header.

Tried the import thing for hours, doesnt work properly.
within this model only the collision-setting for the mainbody must be set the "projectile", then it is fixed.
And yes, I've used a hexeditor a few times.
BUT NEED TO KNOW THE CORRECT PLACE...
The flags are:
define W3D_MESH_FLAG_COLLISION_TYPE_MASK 0x00000FF0 // mask for the collision type bits
#define W3D_MESH_FLAG_COLLISION_TYPE_SHIFT 4 // shifting to get to the collision type bits
#define W3D_MESH_FLAG_COLLISION_TYPE_PHYSICAL 0x00000010 // physical collisions
#define W3D_MESH_FLAG_COLLISION_TYPE_PROJECTILE 0x00000020 // projectiles (rays) collide with this
#define W3D_MESH_FLAG_COLLISION_TYPE_VIS 0x00000040 // vis rays collide with this mesh
#define W3D_MESH_FLAG_COLLISION_TYPE_CAMERA 0x00000080 // camera rays/boxes collide with this mesh
#define W3D_MESH_FLAG_COLLISION_TYPE_VEHICLE 0x00000100 // vehicles collide with this mesh (and with physical collision meshes)

Saberhawk, you are a hero! 
I wasted hours and hours trying to redo the beta orca, but without the best result.
changing the collision settings in the hexeditor is real easy, if one got the trick.
so you have to lock in the header of each mesh for this string: "02 00 04 00 XX"
-> the XX is the Col Settings flag!
E.g. change it to 02 00 04 00 20 to make projetiles hit!
Edit: The 02 00 04 00 was just for this model. The best way is to make an other w3d-file with the settings you like and compare the two files in hexeditor to find the correct place for editing.
Its always the fourth byte before meshname.
