PE is a whole new animal. It lures you in with the false sense of security thinking its just a bunch of tiny parts that will go together like the rest of the kit, but NOT! It will tease you and drive you to the brink if you don't prepare for it.
PE requires a learning curve due to the complexity of the parts, the thickness and quality of the material,and knowing which type of adhesive to use.
I hated it, just like I hated sheet metal shop, until I started actully learning how to use it, now I'm addicted to it to the point I have been enjoying building in 1/700 scale with it.
The key is to pre-plan the assembly. Its exactly like fabricating a bunch of sheet metal parts that you bend then weld them together, only Flea size.
You need to plan how to hold the part, whether its with a pair of tweezers, you make a jig, or use a PE bending tool, then figure out which type of adhesive to use based on how strong the bond needs to be and how complex the assembly is, CA? thin, thick or gel? or will white glue be strong enough? I have also found through research to use glue stick, ticky tac, double sided tape and modelers clay to hold parts in place either permamently or just during assembly.
