As my title says build anything that is not injection moulded.
A quick summary is build anything that could be scratch built vac form wood metal so long as it is not injection moulded.
Basically no injection moulded allowed you could even build card if you so wish
I propose a six month build because of the complexity of some of the kits starting at the beginning of October finishing at the end of April
If I may be so bold:
Build a model built from any material that is not an injection moulded kit. Wood, Card, resin kits are fine. just not injection moulded kits.
A figure can also be of any material (other than the aforementioned injected plastic). As long as some assembly is required.
Most diorama are other materials any way so no worries there. If you are planning a diorama if may contain a finished kit but the build thread must focus on the diorama only, the vehicle can be added at the end. (unless the composition demands otherwise).
For the record, Mini-art buildings are vacuum formed so are fine.
No rules without exceptions.
A resin tank could use a set of plastic tracks. Let's face it resin track links are far from perfect!
If for a wood kit has a few parts in injected plastic, so be it
As long as the majority of the kit is NOT injection moulded.
@peterairfix Is this much what you meant to end with?
