Installing J-11A in 1.5?

[Grafit164DK]

I would like to ask, if is possible to copy New J-11 from 2.5 to 1.5? New 2.5 is totally unplayable on my coputer, while 1.5 works fine, so I am interested if am I able to move new plane (and may be other ones which will be released in the future) to 1.5?

It's not Possible to Copy a New Module to an Version before it was released.

Thank you for clarification.
