Yes it will be in 28mm-scale, I made some small sketches and I slightly changed my view on hot air balloons.
It wil not be so big as I thought (like an ordinary balloon) but it will be more like a 1-person observation- or safety-balloon (to stay out of harms way when giant dinosaurs roam freely through your camp, for people who watches jurrasic park II, the same manner as with the safety-lift when the trailer was attacked by a pair of T-rexes)
I came up with that particular idea while brainstorming about possiblities for a function for the balloon. And I really like it, the building will start tomorrow I guess,...
WIP's will follow during this week,
