The Warbuggy and Wartrakk are easily the two worst models still used in Warhammer 40K. I made these as replacements.
The Engine Folder is common to both models with the exception of the exhaust systems - for a warbuggy just print the warbuggy cylinder heads and for a wartrakk print either the warbuggy cylinder heads or the plain cylinder heads and the wartrakk zoomies. The zoomies don't fit on the warbuggy.
The vehicle drive shafts are not included and you'll need to supply some thin rod for them.
Once you've printed a vehicle then add a weapon and possibly some extra armor plating. You will also need two GW ork Torsos and two GW ork heads to complete this.
The warbuggy frame in the zip file is an old version. Use the one that's not in the zip file.

The intake manifold requires a larger raft to keep it stuck down when the print head inevitably catches on one of the tubes. Probably couldn't hurt to use a larger raft on the zoomies either.
