So I decided to scrap my Starviper mod as I wasn't liking the way it was turning out and decided to add the wings to my already painted Fang Fighter.

Right now the wings are only painted black, but will be painted with some yellow after, and are just being held on by some push-it (the white stuff).

My main problem is that by simply gluing them on top of the model the change will be too brusc and it wont look that good. So I was looking for advice to make it seem more natural, like it came out of the factory like that or, to make it look even more like it was welded on to it. So, any advice would be helpful, thank you.

Here are some pictures:

You can try using some two part epoxy putty. Uncured, it can be smoothed with a brush moistened with water. It will add some extra strength to the joint.

You might consider punching a small hex or circle of plastic to simulate a weld plate and attach the wings to that. If done that way you can run a thin "worm" of epoxy putty around the circle to simulate a weld bead. Use a sewing needle to texture the putty to look like a weld bead.

That's all I have at the moment.

That is so cool! I'm 100% stealing your idea.

@Barry Harker, what do you use on your custom models?
