They mention in the roll-out announcement that they did add a stall-warning vane in the wing that automatically plugged in when the wing was installed. I suppose it would be possible for a similar hook-up to be done for a wing mounted Dynon pitot. Interesting to see if Van's does it on the S-LSA or if it is something individuals would have to do on their own if building as an E-AB.

I'm not an engineer... so I don't know what sort of trick quick-connect couplers could be used to accomplish this. I've seen some pretty amazing stuff in these RV's.The stall warning vane is a simple mechanical device. I personally think constantly plugging/unplugging your vital pitot-static system is perhaps not the best of ideas...

What's the hole in the centre of the spinner? Is it the pitot tube?
Cheers...Keith
It is a pitot tube. There is a closeup photo of it and a short mention of it in an article on the RV-12 in the November 2007 issue of Kitplanes magazine.
It seems that at high angle of attack the nose pitot was yielding speed numbers much too low, so the tube was beveled. That allegedly corrected the problem.
What is the silver/white handle that extends past the bottom of the right side of the panel? A parking brake? Flaps?

I agree with Bill on the toe brakes. From what I can tell, pushing on the toe brake rotates the assembly at the bottom. The brake cylinder is mounted on a tab, and the rotating action pushes it upwards against the rod.So, is this what the mystery Autopilot switch and fuse are for:

As for the brakes, it looks like the toe unit swivels forward and activates the hydraulic lines...

What is the little recessed push-button switch above the fuse panel? It looks like it has it's own fuse which has tape on it.
I'm thinking of heading down to Van's this week to look at the -12 and get some better pictures. Is there anything special that people want me to look at/take pictures of?
--Bill
Yeah... they're busy in there working on my "2+2/Stretch-9" and "RV-4 based LSA High-wing Parasol" which I'll be building as planes number 2 and 3 after my RV-12.The proto shop is way off limits, so no chance of getting in there. --Bill
Van's is the manufacturer. He can do whatever he wants so long as it meets ASTM standards for LSA. The manufacturer must approve any changes that you want to make.What happens when these get replaced with newer units (Garmin, etc) and someone has a failure and needs to replace it. Will Van's need to re-certify and add new units as time goes on? Will there be a more general guideline of what can be used?
Thanks, Joe
Only Van's can answer that.So there's no "standard amateur built" option (like current RVs)?
Even if I did know anything, I would not be at liberty to say.Mel--
Any idea if the FAA is thinking of revising the EAB rule? I had heard that other manufacturers were complaining of the new interpretation, but haven't seen anything on it come out of Washington.

I spoke to a unnamed source at Vans today, Wing kits will be for sale at SnF
and on the web April 8 with the rest of the kit to come,
Hmmmmmm....wonder why Vans will release the wing kit, but not the tail kit. I had planned on purchasing the tail kit first.
Don't know if demo flights will be conducted. The latest -12 to fly is being trailered to Florida because the time has not been flown off.
I think 412RV is an "Experimental" as it is still a proof of concept. Subsequent -12's will be E-LSA. I'm not positive on this so verify with Van's.What time do they have to fly off 412RV? Do they fly 40 for experimental? Or 5 for E-LSA?
I don't understand you comment. If Van builds an S-LSA, he must fly off a minimum of 5 hours. If you build an E-LSA, you must fly off a minimum of 5 hours. If Van or you build an amateur-built, someone will have to fly off a minimum of 40 hours.If I understood Mel correctly, Van will have to fly off the test hours and the builder will have to fly off 5 hours if it is E-LSA.
Usually the FIRST LSA will be done in R&D which will require more testing. Once the concept is proven then it goes into LSA and only requires 5 hours. Also remember this is a minimum. The designer will undoubtedly do more than the minimum testing.Sorry Mel, I was making an assumption from posts 65 and 66 that the mfg. of the S-LSA would have had to fly much more than 5 hours to insure the reliability of the product.
