Glad its working well so far! Not surprised that she's buckling here and there, I'll whip out the hammer and chisel, and make some internal bracing and templates for the next version. Lots of glue marks, uncoloured edges..... Hey that's what a beta is all about! slap it together quick and nasty, so she can zoom around the room, and blast the bad guys. ( insert appropriate sound effects) You've done well considering there is no guide or part numbers, give yourself a gold star! you'll be able to write/compile the assembly guide with your eye's shut. *Do you think the Engine Buckle issue, could be fixed with some bracing/internal template or do recon it needs a bit of a redesign? ,,,,???... as in make the engine module more of a 'box' shape = without the groove, then add the ridges on to that as separate parts? (The flaps can be made to resemble plating) *What sections would you brace ~ if you can give me an idea of what you had in mind, I'll try to supply them in card with the model. *Were there any parts that you found to 'Fiddly" or complex to fold? = would have been easier to assemble from smaller sub sections? *How big is it going to be? = Printed on 'letter' ? big enough / to big? Master Plan ~ Once the basic construction issues are ironed out, I'll dev some surface detail = bridge, ( build-able ) Engine ducting etc. ?? plus, rather than a bunch of complicated part number/placing issues, I had in mind to supply a page with some generic shapes, plating, pipes etc. Then texture it with bitmap editor for the polished goods. Thanks for the assist and feedback Doc.
