MSH Protos 500 450 380 Aerobatic Electric Carbon Fiber w/ Parts

Protos helicopter I’m not sure if it’s 450 or 500 size the blades are 45mm long. It was supposedly only flown a few times the guy was scared of it. I used the servos in a different build it has a speed control and motor in it. Chip on front of cowl. Blades and tail rotors in smooth good condition
