The Sling2 is maxed out in other parts of the world at 1540 lbs and is one of the reasons I am looking at it as a purchase, in case the max weight for LSA increases,I would possibly be able to take advantage of the increase.

I understand the reasoning behind not flying over design limits for LSA designed for 1320lbs, and am not willing to fly over the 1320 lb weight in a current Sling2. My question is if the weight changes do occur, would the Sling be safe at 1540, since it's designed for that weight, or does being "LSA" preclude that?
As Warmi stated, existing Sling 2 LSA’s are all built the same. The factory has already stated they embrace the change if and when it comes for existing aircraft. Until that time comes, if you fly in the USA, it’s 1320 until the change, unless you’re EAB.
And have a Private Pilot certificate and 3rd class medical or Basic Med.
Yes, which I have.

Even with an E-AB, you can't just arbitrarily change max gross weight. You're limited to whatever the DAR signed you off for.

Yup, I know a fellow pilot with a E-AB RV-12 LSA and he follows all the same rules I do except he needs an A&P to do his annuals and not a LSRM. I'm sure there are other rules but it's still an LSA and he follows the LSA guidelines.

Correct, build a Sling 2 and it’s 1540. Cam’s Sling will be 1540.

Yeah, the factory let’s you build Sling 2 planes as either 1320 lbs Light Sport or as 1540 lbs EAB.
It is the same plane just different certification.

The gross weight can be changed for E-AB fairly easily depending on when the operating limitations were issued. Older operating limitations may require requesting a ne airworthiness certificate, but it is just a paperwork issue. No new inspections are required. Newer operating limitations just follow the requirements for a major change, which include notifying the FSDO and placement back into Phase 1 flight testing.

Which the OP does not have or plan to get and the guy who asked the question. I am responding to him.

Thanks for the clarification, Tom. I've never done this for an experimental, but I did raise the max gross wt of an SLSA to 1320 from a lower number. It required an FAA airworthiness inspector to personally verify the mod (and the revised dataplate) and issue both a new airworthiness certificate and new Operating Limitations.

I don't think that E-AB operating limitations actually have an assigned gross weight that is approved by the DAR.

Then, who establishes E-AB operating limitations, if not the DAR?

Yes, but - wouldn't all those groovy performance charts and specifications in the POH have to be modified to allow for the potentially increased maximum load? Same conversation was held some years ago regarding the Cessna Skycatcher, before it was discontinued. Would Cessna recalculate and retest the data to provide the updated info to the approximately 200 odd owners? Or, how does that work? Good Luck, Chuck; you're on your own?

The DAR establishes limitations, but not performance limitations like standard category aircraft have.

Caution: This post is purely speculation on my part.

Or, Cessna could simply say, we have not tested the SkyCatcher to any higher weight limits and are not going to recertify to a new LSA definition. Why would they since they are no longer selling new SkyCatchers?

My guess is manufacturers who have tested their designs at a higher weight will offer a new model at that higher weight. If allowed by the new regulations governing LSA I suspect they would also offer a path for older aircraft that can safely be flown at a higher weight to increase their gross weight as well. Until the new rule is out no one knows what will be possible.
