When I first received this kit when I started to read through the instructions, I was immediately drawn to to the main wing flaps. I noticed that all of the structure of the flaps was photo etch and each piece seemed that it involved some very hard bending. The Photo etch on that comes with the Great Wall Hobby P-40 (GWH) is very thin and thus you get maybe two attempts at a bend and after than the piece will separate. Their instructions show little arrows along each piece which is how you are supposed to bend the parts but I found that the arrows and directions were less than stellar. You also have one long piece of plastic that is to help support the lower flap when opened. I assume it’s an actuator arm. For each side of the wing, you have 8 different parts that have to be added. There are a few issues, the main one being that it’s very hard to hold the parts once they have been bent since due to the folds you cannot get your tweezers around them without resending the folds back over. You can take a look at a few of these parts in the image below.
Once you have all the various piece folded you can line them up along the wing to attach them. Here I ran into yet an another issue in the alignment. Make sure you allow for the large single piece of photo etch that sits on top of 3 of the supports. If you don’t have the correct alignment, this piece will not look correctly placed.

I had planned to use Ultra glue to attach these parts to the plastic. Ultra glue is made by “Ammo by Mig” and is an excellent glue for photo etch. However the pieces need to be able to fit flush with no resistance as the glue does not have an instant bond. Instead I had to use Cyanoacrylate (super glue) to get the parts to stick in place. This was a bit tricky since you have to make sure you have the correct alignment before you stick the part. If your alignment is off, it’s best to use the cyanoacrylate debonding agent, pull the part off and start again. My finished effort is not perfect, but I am overall pleased with the final look.
