Frank,
Neither Van nor Rian mentioned the new wing design and I forgot to ask.
The current fuel tank is welded aluminum sheet. Other materials are being evaluated. They want to stay away from proseal if at all possible. The tank resides behind the pax seat to allow for a simple folding wing design.
Steve
PS
It's a tight fit under the cowl what with the radiator, ducting, and hoses leaving little room for a battery.

O.K., if Vans high number of 1000 hours is used, 18 months is 78 weeks, and that is less than 13 hours a week.
Figure Van doesn't know what he is talking about, it will take half again as long--------and go for 1500 hours build time, and you get less than 20 hours a week.
I think you can fit that into your schedule, if you try.

LOL -Yeah... but you haven't seen my schedule!  (Remember, I am in the busiest unit in the state... and there are unfortunately whole weeks where I will get nothing done due to work.) My numbers aren't precise, and admittedly probably conservative. While I would hope and plan to work more hours, I look at an average of 8 hours a week. Just trying to low-ball my hours so I don't have an unreasonable expectation of the project.
As mentioned - luckily I don't have to make a choice today. I'm not ruling anything out. Because of so many converging issues, I wanted my first project to be on the less expensive/faster build side which the LSA seems to address. (That, and the exact plane I will need/want just isn't out there yet -something like a "Stretch-9")
Thanks for the encouragement!

Kits may be available later this year.
Build time is estimated to be between 800 to 1000 hours.
The rivet holes are pre-punched to final size. No drilling, deburring, and dimpling required.
A quick build kit option is NOT being considered.
Estimated finished cost is between 40K - 45K.
The airframe is designed only for the Rotax engine.

Thank you for the update. Did anyone mention anything about the length of time it took to remove the wings?

Jabiru for RV12
I attended the Jabiru forum @ Oshkosh. Pete Krotje said said that Jabiru anticipated offering a firewall forward kit for the RV12. Or did he say the RV9? can't remember. Anyone else there?

The J3300 would be an interesting choice for the -9. Might be a bit underpowered, though.
The J3300 spins pretty fast at 2,850 max continuous (112Hp) and 3,300 max TO (120Hp). Power is down to 100Hp (83%) at 2,600. So, unless you had a CS prop, you're never going to get to the 120Hp figure; otherwise, you'd be loosing a lot of cruise speed with an underpitched prop. This would limit the climb a bit, but make for nice cruising economy. Not sure about the long-term longevity of the Jabiru.
I did enjoy flying behind the J3300 - much simpler than the Rotax for an LSA engine. It makes sense for the -12 for those who don't want the complexity of the Rotax and want something smaller / lighter than the O-200 at 178 lb with exhaust, starter, generator, dual CDI, etc. No mixture control with the altitude compensating Bing carb.

RV-12 News
I flew into Aurora OR. on Friday the 3rd. Took a tour of Van's factory. I asked our tour guide Rob when they expected to have the 12 ready for builders. He stated Dec. Hope this helps. I myself got my Demo ride in the RV-9A and walked out the door with the Preview Plans for the 9. The project has began. Went to Lunch in Independence. Their setting on the ramp was an RV-9 just out of the paint shop.  The owner was as proud as a new Father, I guess in a way he was. If I figure out how to post photos. I will do so.

Jabiru will be looking at the RV-12
We will be doing a FWF for the RV-12 as soon as we get the final details of firewall layout, thrust line, CG limits, etc.

Good to hear that Jabiru is on the job here. I think this could be a good market for the J3300 if you had a good FWF package.

Might require a longer nose - which may make the RV-12 look better. It will be nice to have another engine option - especially the Jab. I would have to assume that putting out more max HP, it will really climb out on initial, before you have to throttle back. And, developing more HP at say 75%, will probably yield an even higher cruise speed for those of us NOT building the RV-12 as an LSA. For the LSA types, it may have to be really under propped (is that the right term?) and would climb like a rocket...
Pete - understanding that you are a dealer for Jabiru... but any thoughts from the manufacturers side regarding the current status on the 3300 - IE reliability claims, TBO, etc.? Any 3300's gone to TBO yet?

It would not require a longer nose. The Jabiru is heavier than the Rotax. I had to shorten the nose of my bi-plane to accommodate the 3300.
