The frame work of all four parts, the left and right flaps and ailerons are pretty much the same and is technically fairly easy to assemble. In reality, however, I made many errors because you need to be sure which is what and what's up and down and outer or inner. And once you removed the identity stickers for anti corrosion treatment you're left with your memory. So, there is no use to try to make it fast. That will only stall you. Just take it easy and sip a lot of coffea. When the coffea is cold you'll have it all sorted out. All hinges and reinforcements are now on the right places and the skins are tightly rivetted. It's amazing how light these parts are - and still very strong.
Now I need the rivet gun to close the trailing edges with solid rivets.
