This is a brief comment from someone who was has been seriously considering ordering an RV-12 kit:

It sure seems like there have a lot of changes. I would feel a lot better about placing an order if the design had been stable for at least a year.

You would not say that if you were buying a computer would you?
Think of the RV-12 as a pack of aluminum sheets bundled with a computer

On the flip side of that comment, I for one am extremely happy that the design has continued to grow and improve thru these changes. Seriously, none of them have been dealbreakers, and all have been improvements to an already fine design. I would be disappointed with a company that did NOT do that.

I'm thinking having a design stable for at least a year might rank right up there with having a house that's finished. I've never seen one (house that is).

My 1967 Cessna 150 had a change, requiring parts to be changed, in Dec. of 2009, when it was 42 years old.

On the other hand there's certainly nothing wrong with waiting. For me personally, there hasn't been any changes coming down the pipe, that would of kept me, nor did keep me from getting started.

If I thought that my airplane had anything close to the reliability of a computer, I'd be walking!

Then again, it sure would be nice to just reboot when the darned thing went teats up.

Default RV12 polyethylene tank with fuel cel safety foam

Does anyone know why Vans doesn't provide a poly tanks like Sonex does with fuel cell safety foam to minimize slosh? It seems safer, would cost less and much easier to build/install.

See the latest in poly tank design on page 53 of the Jan Sport Aviation(yellow jet on cover). It's mounted low and behind the pilot. And has to supply fuel at rates just a bit higher than a 912S

Just thinking out loud, but it could be as simple as the fact that they have the machinery to bend metal, so bending metal is what they do. It's not unlikely that they looked at the return on investing in new technology for a single entry in their fleet just isn't there.

There's nothing stopping a 3rd party from stepping in with a replacement tank, except for similar economics - how many would they have to sell the recoup the investment in custom design and engineering? How many 12 owners would be willing to make the change, especially if this latest SB is finally the last?
