One kit (would have to be 1/72) and everybody builds the same.....
One day, start to finish.....From breaking the seal to weathering. Speed-bashing.
Only OOB of course.
Couldn't be live due to time differences but progress could be updated.
Then post pics and full desciption of how it went, however it ended.
Could be set up for a Holiday or weekend day too...Well in advance.
I think it would be really interesting to see what a group of builders did with the same kit under a tight schedule. Might be worth the logistical nightmare of clearing the decks for a one day build. But who are we kidding, It would be a blast.
