actually i have found this voxels in TS Total War mod. and i was trying to remove the rotor because it totally unused in TS.

This voxel was originally made by Ackron, it can be found here

Taking the rotors off was also done by Rico on PPM, on the same voxel - found here

Unless you are Rico, I'd suggest giving him credit if this came from him.

I also made a version of this voxel which had animated rotors, for a hva tutorial I began a while ago, long since abandoned.
EDIT: found it.
To make the animation work though you'll have to either use this in RA2,
or in TS make a it vehicle with the flying locomotor, which makes it somewhat buggy, and invincible during flight - but it'll look cool~

Thanks for watching over the vxl, but its really Ackron that needs the credit, I merely edited his work.

I'm just replying to let people know that the vxl has been updated. Also I have made a GDI variant, was wondering what people thought of it
