The wheelbase is different, YIKONG YK4083 is 10mm longer than YK4082.
YIKONG YK4083 shell is newly molded with better details and lighting than YK4082.
There are also different shells, different approach and departure angles, and YK4082 is a bit stronger in terms of data performance.
Other than that the difference is not much!
That said, a lot of the parts should be universal, except for the shell.
