Hi, everybody. So after struggling with my P4 I understood that DJI won't fix the problems on it and it is actually getting worse and worse. and I decided to move on to Inspire.
My question is Can I buy Inspire body only and use my Osmo's X3 camera on it? Thus saving some money.

Thanks

No, the OSMO camera won't work on the Inspire.

Inspire cam will work on OSMO, but not the other way around.
There are hardware differences apparently.

Inspire has dropped in price quite a bit lately.
Be aware that the Inspire has a few quirks as well - be informed before you shell out the $$ and make sure that it will do what you want it to.

thanks for great info, Do you know what kind of problems does inspire have?

I didn't say problems, I said quirks.
The Inspire is a solid ship - very capable and you will be impressed coming from the P4.
Just suggesting that you do your research before spending the $$.
