Hi everyone. I'm new to this site and fpv. Looking for ways to lighten my drone without too much cost

Welcome to the site!

Gotta post what you have before we can make any suggestions...

Welcome.

What I have found is that my wallet is much lighter since I started into the FPV hobby
But it is really much fun.

I've got a 5 inch rooster clone but I've seen a 4 inch frame that fits my 30x30 flight controller but i don't no if I'd have to downgrade my motors as they are 2205 2300kv.

Welcome to the forum! You won't find much difference changing to a 4" frame with the same components. Keep that 5" as is and build yourself a little 3" screamer. They're a ton of fun!

Welcome !

I'm trying to save on money to start

HI and welcome

I'm thinking of a challenge but I don't know if it's possible. Transferring everything off a 5 inch and onto a 3 inch?? Any input would be welcome

Well, since you have a 30x30 flight controller you would need to find a 3 inch frame to accomodate, I do believe there are some but I don't know of one off the top of my head. Also, 3 inch frames can pretty much only accomodate a 4in1 esc setup, small vtx and micro camera. Motors will have to change as well.

There are some lightweight 5 inch frames out there. You haven't really stated why you are trying to save weight.
