i have the original Q 500 4 K ( black ) and after my crash ( after almost 3 years ) i had so much invested in my first Q that i had to buy another , of cost at half the price , i though my original Q would never see the sky again ( air frame busted , camera all over the ground props gone , battery 20 feet away ) , but after some down time i opened the Q up and re soldered all broken wires and got GPS lock and all motors and ESC 's were working is when i bought the new air frame , it is the last version , for the most part they are the same , you may have the latest frame .
good luck , if i can help let me know .
fly safe
