Thought you might like to see some pics of an Asiatam Stug IV I am currently building, its not the easiest thing to work on but not so bad either. I bought it ages ago from an ad on this forum, it consists of the asiatam metal hull, stug top kit and an SLU system.
So without further ado here are the photos:
First step was finding out as others have on the forum, that the lower is a tad longer than the heng long, the irony being the Stug IV upper is the same as a heng long lengthwise, so even asiatams own upper wont fit the lower
so out came the hacksaw:
Also found the rear plate was warped but managed to straighten it.
Next was to build up the suspension, its not the best as others have observed, biggest problem for me was the self tappers asiatam supply to hold the wheels on. The holes in the bogies were unthreaded so I ditched the screws supplied, drilled out and tapped each arm to an M3 thread and used a machine screw instead:
The return rollers are also a problem, the axles supplied are stepped which in theory prevents the axle from binding when the nut is done up inside the hull, sadly though they dig into the metal roller mounts when tightened so I found a point where the axle is tight but still lets the rollers turn, then superglued the nut in place.
I also modified the fairly weak asiatam idler tensioners so the axle of the idler is locked in place by a grub screw, without this the idler axle tightens itself going back and loosens going forwards....
Gearboxes went in:
Next step was a primer coat (Wilko grey primer works well on the aluminium hull)
)
. I swore after the last tank I wouldn't do another, but on this kit it does hide the gaps
