You have to know that only the Germans would develop something this crazy to fly. If they could come up with a jet propelled Meteor, than this is nothing. It actually was a very challenging build. Thank goodness for all the sub assemblies that give time for each other to dry. Because I would recommend just that. Let each step dry thoroughly before moving on. Some procedures felt like I was trying to glue toothpicks end to end. The instructions were sufficient and the locators were also sufficient. What was lacking was in the paint schemes. Some were okay and some needed modified. The only real problem I experienced was that the blades were heavier than their wimpy mounts would tolerate. I had to beef up the joints with extra glue to hold them. The decals were good but, all in all, I would only recommend this to serious modelers. It was definitely challenging, but fun. I love Helicopters. See my photos.
