I'm building various r/c vehicles like warplanes, tanks, auto-turrets, etc. and I want to fit some of them with some kind of a weapon. I've decided an air soft gun is a good choice. So, mounting and shooting the gun is easy. The problem begins, when I want to create a software damage model for my vehicles. I need to find a way to detect when and where my model was hit.
I'm thinking about to layers of plastic or some other slightly elastic mterial, each covered with sth conductive. They are placed close together. When a bullet hits one, it bends, touches the other and the current flows. However it doesn't seem to be a very elegant solution. Especially when it comes to hit angles like 60+ degrees or centrifugal forces acting on my plane. I don't think it will also work on sloped surfaces like airfoils etc. I will also probably fail on thin surfaces, because the sensor would be quite thick itself - the upper layer, the conductive things, the gap, etc.
Is there a better way of doing this? I'm really out of ideas so any help means a lot. Also, please don't tell me how good/bad my idea is. I just need to find a solution to a problem.
P.S.: I don't need an exact hit location. Locations like: wing, elevator, first half of the fuselage are totally fine.
