Patience, Patience, and more Patience.
As far as any tips. Here is one that I struggled through my first PE go round.
With plastic it is fairly easy to use glue and hold the parts. They were designed to go together pretty easy (especially Tamiya).
With PE very many times you're dealing with itty bittty parts, CA with short work times and tight sweezes.
So - what I do is get all parts clipped, files, folded, prepped first. I test fit then I test fit again. Then I kinda go nuts and test it again.
If I can I will clip the receiving piece into a 3rd hand tool (not always easy).
I have a small scarp piece of foil or tile, something smooth and I drop one drop of CA on it. I take a piece of hobby wire and dip it in the drop. Then apply the CA to the receiving piece.
I then (using itty bitty tweezers) take the mating piece and place it on the glue. I try to use gravity as much as possible. I position the receiving piece as parallel to the ground as possible that way I don't have to worry about holding two pieces together.
Here are some more!
Couple other things - WATCH OUT FOR TWEEZER LAUNCH!!! Clean the floor and bench before you start working. It'll make finding the part easier. Be gentle.
Do your homework. I found that while the PE is very detailed it may not be totally correct. Research any questionable fit. I do more home work with PE than anything else.
One thing I do with PE is go through the kit instructions and highlight (circle) each part/assembly that will be affected/altered by PE before I do anything. That way I won't forget that I need to change my process.
Other tools you'll need (or that will be helpfull) a dremel/grinding tool to remove the plastic parts. Nice files for plastic.
Last tip - Ask questions!
