OK..we are moving. After spending 6 days putting 140 models in their boxes I vote PMA as being the most difficult to models to repack. Those with the 4 plastic pegs under the Styrofoam shell. Some AA are using the same but at least their pegs are in a funnel shape so the screw fall right in the hole of the peg(well almost). My most dreaded model was the Exoto Alfa Alfetta rolling chassis which was quite easy after all. The easiest one were the Kyosho with the cardboard strap around the Styrofoam clam shell. There is for sure no consistency when comes to packaging!
