Here are some tips for when you assemble and load the Boeing fuselage onto the flat car.
1. Be really careful with the supports and ice breaker piece, they are 3D printed and use filler support strands (just like sprues) to support it while it's printed, these need to be removed but the ice breaker is quite fragile and even though I used a great diagonals I managed to break the ice breaker, a little CA glue fixed it.
2. For putting on the decals, it's best to watch their video, thankfully Robert
showed me this link and I'm sure it will be a help for others.
3. I used CA glue to carefully line up and glue on the supports, I used their picture on the instructions to see how it should align up. Basically, the front support lines up with the letter "B" on the flat car, glue this support on first, and let dry, then put the fuselage on it, with the rear support to see where the rear one will go, glue the rear support, then put the fuselage on to check for alignment before the glue dries.. This takes patience since there are no guide holes on the flat car.
4. Take your time and have fun, they give you an extra decal set in case you mess up.
