What type of plastic are the arms are made of?

[RichK69]

I need to plastic weld a crack in one of the arms, to use the correct filler I need to know what type of plastic it's made of? e.g. Polycarbonate (PC), PC-ABS blends, Nylon, etc. I've looked online but haven't found anything, does anyone know the type of plastic it's made of pls?

It is HIPS Plastic (high-impact polystyrene) BUT before you start applying the JB Weld does this crack interfere with the flight of the Drone? Does this crack get bigger each time you fly? What Drone is this?

The best adhesive I've come across that gives an astonishingly strong bond but retains enough flexibility to resist cracking or breaking under (reasonable) torque is B7000. Other epoxies will bond, but at some point will definitely fracture under stress.
