Hi
A Little help required if you please gentlemen and ladies(Of Course)

I am currently elbow deep in one of my little projects and trying to figure out turret rotation
The model I am working on has a turret ring diameter of No bigger than 63.1mm diameter and the turret itself is only a few mm bigger.
This is way too big for any cut and shunt off a tamiya kit. Can anybody think of any model I can kit bash
i.e a heng long model that has a turret ring less than 63.1mm diameter.

what about one of the smaller 1/30th heng longs? the must have a smaller turret ring. hope this helps.
