Spot on L4

The Amphibious APC is on hold for the time being. It is mounted a bit differently on the chassis than the other turrets (which simply sit on top of the hull) and there's some issues regarding the front hull vision slits that might cause problems. It would be easy enough if people were to carve off the slits before mounting the turret, but Tom would prefer if people could just assemble the model straight out of the box. This either means that some kind of holes need to be made in the underside of the turret, where the slits are located (which again causes some problems with metal that may be too thin to cast on the sides).
We also discovered that the models shrink a bit durig the bronzing and moulding process meaning that the production MBT hull is in fact almost 2 mm shorter than the blue version from Print A Part. We need to know if this shrinkage is consistent before attempting precision work where 0.1 of a mm would make all the difference if the turret fits or not.
An alternative option is to have one more MBT hull made which accounts for these problems but of course that is much more expensive, so there's also the question if an amphibious APC generates enough interest to be profitable.
As it is right now, there's no plans for further turret variants untill some other projects have been realized. ...But of course the project could be revisited if some great ideas pop up in the future.
Right now Otterman is tinkering with the treads for the updated Enforcer Super Heavy. The plan is to find new areas to improve the detail based on the lessons learned from the MBT.
