Thanks a lot guys,I'm glad that you liked this model;finsrin, i was actually thinking on using the same system,used on a 1-144 scale ,f-14 or a Tornado kits from revell,but instead i used two simple pieces of plastic,cutted in a shape of a wing,but the must difficult part ,was to make the holes that attached the wings on the right place,so that they could swing backwards,but in the end,it came out OK.
best regards
Pedro
