Default RV-12 Gross Load with new LSA rules

I realize this may be a loaded question for some and a liability question for Vans. However, I think it's worth asking.

I'm considering an RV-12 and have a sport pilot rating. Before I drop 100-140k for a new or new to me RV-12 what will the value be if the new LSA rules increase to 2000 - 3600? Would the RV-12 design allow for some increase if the new rules take place? Will the values of these 1320 LSA drop significantly?

I know there are some LSA's in the market that are certified elsewhere in the 1500-1600lb range. They are only limited by the 1320lb by FAA restrictions for LSA. I'm curious if anyone knows the actual design specs of the RV.

I would love to hear some thoughts on this topic.

Following! Iím contemplating building an RV12 myself. Iím interested to know if vans will change the Max gross weight (if the plane can handle it) and specifically what the changes might do to values.

First........Only Vans can answer that question. My guess is that the RV-12 was designed to the 1320 lb. specification and there is no margin for an increase.

Second.......I would not hold off on any decision waiting for the FAA to make that change. These changes literally take years to finalize.

Even if the rules change those of us flying are stuck with Max gross weight specified when we applied for our airworthiness certificates.

It’s not a big deal to get a new airworthiness certificate.

Purely speculative thoughts:

Even if the airframe could handle higher gross weight, and Van's made a decision to move in that direction, there are still challenges to effectively adding useful weight:

- engine/prop combo performance at higher weight
- the cost of changing engine / prop to achieve adequate/acceptable performance at the higher weight
- the effect of higher weight, different engine/prop, required changes in fuel capacity on CG limits
- reduced utility (space) with increased fuel capacity. Wing redesign not practical to add fuel capacity.

Bottom line - my guess would be that Van's would go another direction to accommodate significant changes in LSA weight limits, either changing the RV-12 design substantially, clean-sheet design, or modification of existing designs (9/9A, 14/14A?). The possible exception being a very modest (say 1350 lbs) increase in RV-12/12is gross weight if the cost to do so is reasonable AND the airframe design/ safety margins/ CG envelope permit. That small change would dramatically improve the utility of the 12 IMHO.
