The model is a lot of fun to assemble, but it is quite challenging. There are many, many very small parts so if you suffer from a loss of manual dexterity, this is not the project for you. Some of the parts require additional unspecified waxing, sanding or filing to ease their assembly. It took the breakage of a couple of small circular parts to “learn” this. I am hoping that their are a couple of spare pieces included in the kit to replace these parts otherwise I will not be able to fully complete the kit and that would be a shame after all the work put into its assembly.
I was very impressed with the way it snapped together. The only suggestion is the directions should have emphasised the need to lubricate the moving parts.. There is way too much friction envolved for it to work properly.. I did use the wax very liberally but it wasn't enough. t
