Warped pieces.

Hello!

I checked out the sprues one more time and I believe you are talking about the lower wing part being warped. This would be a minor problem, because the top part has those heavy steering surfeces molded, that could act as reinforcement. What I would do is I'd dry fit it and then take lacquer thinner for glue, apply it heavy on the lower part (so that it penetrates a little and softens the plastic), then I'd mate the lower and upper wing part together and just then place the wing in a jig to straighten it out, clamped in three - four spots.

But is it worth it? That Hasegawa A-4s have that nasty dimensional error - the fuselage is much too long! I believe the Fujimi Skyhawks were much better, and you also have the option of grafting on some Airfix parts - the Airfix Skyhawk is a thing of beauty.

In any case good luck with your build and have a nice day

I have no experience with that particular kit, but I've had plenty of others that have had a warp issue. Cementing it to the other piece is usually enough to take care of the problem, or at the very least, make ok enough to "pass".

Maybe try dryfitting them and just using tape around the edges, to see if that will do. If it works...glue away!

put the pieces into warm to hot water til the pieces are plyable then put onto a solid flat surface either clamped or taped til pieces cool off & stay flat.

You can't rely on weight to hold the warped part straight. You have to physically bend it straight while it's still hot. It may take a few tries. Hold the part in boiling water for 15-30 seconds, then remove it and bend it straight. The downside to just leaving it alone and hoping it will straighten out once clamped to its other half is, that it wont straighten out completely, and once it's glued, you've screwed yourself. 

I have used the hot water method in the past. I have heated water on the stove, to almost boiling. I then put the part in until it warms up. Quickly remove the part and bend it slightly past straight. Most plastics have a bit of a memory and want to go back to the warped position, so going a little past straight counteracts that (usually). May take a try or two to get it right. Warped and twisted are a bugger to get to get right.
