Split the model

I found this tank model on wc3search. I want to split it into two models, one with gun only, and second one with rest because I want them to move separately (independent or how you spell it ). I tried to remove unneeded parts with Vertex Modifier, then save the model, but this model was crashing my WE. Someone wants to try?

Here the model:

TANK

If you deleted the geosets, then it will do that. Make sure you leave one triangle thing in each geoset and just scale it down or move it below the surface.

If you can work out what's what in Magos', delete them there. That will handle any geosetanim etc breakage.
