Default RV-12iS Details

Spoiler Alert! If you are at OSH and anxiously awaiting the arrival of Van's new iS airplane and want to discover all the little details up close and personal, then stop reading now. She is on the way today (Saturday) so should be there on display by Monday. Otherwise, I'll share some of the details I learned yesterday at Van's headquarters with you here.
____________________

Of course the fuel injected engine is the main attraction and that will no doubt be
the major source of discussions at OSH.

This is the airframe systems VR (marked B) and it is cooled by one of the ducts on top of the cowl:

The cowl VR cooling duct:

There is another VR for engine systems. Neither are Ducati.

Some of the bigger details include the center console with the new throttle. The detent is a stop at what is the best economy cruise, as I understood it:

Van's is experiencing significant fuel use improvement and a bit more power. Ask them about it.
The electric flaps are fast but not as fast as the johnson bar. There will now be a flap position indicator on the display. When toggling a Go-Around on the flap switch they will retract in about 3 to 4 seconds.

I also noticed that the ammeter on the display is "Generator" amps and not "Battery" amps as before. This in my opinion is more useful information if it shows the actual generator output.

And, there are a lot small details that may not be noticed in all the ballyhoo. Nice little details.
Like they added a holder for the oil cap on the oil door:

Those louvers in the top cowl are to cool the ignition modules, one of the many changes needed to adapt the iS engine to the 12.


More nice details:
The MLG entry points into the fuselage now have removable covers with rubber seals:

These I think will be retrofittable.
They have added strengthening gussets to the cockpit rails:

The gascolator is now behind the rear baggage bulkhead as is the ADSB-in black box. The ADSB antenna is now a small post type like the transponder antenna:

Default RV-12iS Details #2

The ADSB antenna now only needs a short coax. No wires or Coax have to be routed through snap bushings in the new fuselage.


The ELT is now located under the baggage floor with an access cover:


More little details -- headset hangars:

The upgraded steps come with plugs for the tubing:

An improved canopy hold open catch and canopy latch:

The hold-open catch is easier to engage, and the handle rests on plastic instead of the metal roll over bar.

The translucent filler neck so you can see the fuel when the tank is full:


Some new nomenclature will have to be learned:


There is a new muffler based heating system with heater doors for both pilot and copilot sides; an attempt to improve cockpit heat. The old water radiator heating is least effective when the wx is cold.

I did not see a rocker switch for the autopilot. Assume (not always a good idea) that you would need to pull the AP fuse if the AP servos would not let go of the aircraft for some reason.

The optional stab fairings are a good looking fit; lots of rivets are used:


The lower cowl inlets look a lot different from what we're used to! The coolant radiator and oil cooler are up front. The duct on the lower left side of the cowl is the heater air intake.


There is more to come as development continues, including the panel with an IFR navigator...

I wonder if filler neck could remain in current position behind the rear window and extend with a longer transparent flex hose to the tank?

Maybe Van's could give builders an option for the tank filler location, new or original.

That might be the only thing needed to clinch a deal for me...

Default Cowl Material?

Tony is the cowl made of aluminum rather than fiberglass? From the look of the vents on the top it appears to be.

The cowl is fiberglass.

I wonder where all the water goes when you fly in heavy rain. Top louvers duct air/water to the ignition modules and the NACA inlet ducts air/water onto the voltage regulator and what looks like the FADEC engine control.

This is out of the 912iS HMM (look at manufacturers name etched into the edge of the case.)

The good news is there are no bing floats.
The ECU should be reliable, it's made by Rockwell Collins.

So…is there a new fuselage and engine in your future??

Mike
Actually, N912VA, the plane in the pictures, was done that way.
If I were to build another one, I would start from scratch. I enjoy the building part.

There will be no option.

The hose used (and shown in the photo) is resistant to effects of fuel exposure but it is not a flex(able) hose.
It can be bent slightly but only enough to allow getting it aligned as installed. It would be impossible to bend it aft to a different filler location.

Hey, just curious what happened with this feature. IIRC, the tube in my iS kit was black.

As a point of reference, my Finish kit shipped early Feb. 2019 and it's black too, so also interested to hear the answer. Sounded like a nice feature.
