eh i guess for a easy solution you could throw that together but i think making the materials degrade over time and when they're old enough just break and need repairing/replacing. leather parts and things of that nature would degrade fast so you'd be replacing those a lot for so many uses then the wooden, or whatever it ends being, frames eventually get worn down and parts of them break.

you'd be able to check on the rate at which its falling apart through visual cues and analyzing it(right click for a description which tells you how it looks). eventually you could have parts breaking down in mid-flight, after landing, right before trying to escape.
