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.

I would use MEK. Just use a small syringe and flow a tiny bit into the crack. The mend will be almost unnoticeable.

But that's also because I have 10 gallons of it.

If you do it make sure the motor is EXACTLY in the same position it was, Otherwise your other motors will suffer the consequences.

It's the MP1. I won't be using a glue or epoxy but plastic weld it with staples and fine wire mesh, this will surely be a stronger joint than glue.
