Just an idea - -
I have over 700 hours, and have not had a VR problem. I also have minimum demand for power. No lights, second screen, AP. If I had/have a problem, I think I might consider putting it in the air duct. Would seem you could cut out a square just big enough to allow it to go inside, and mount it on a fairly firm plate and could even use nut plates and bolts to hold it in place. Air-flow would be great, and away from engine heat upon shut-down. I don't think it would restrict that much air-flow thru the duct. Just a thought. Have not looked at it with cowls off. Might be hard to do. You would get smoke etc inside during winter with the heater on, but could close it quickly, if it ever burnt up, but less likely with a serious airflow.

Tom,
What do you mean by SK regulator? Are you referring to the SILENT-HEKTIK? If so, my interpretation is that no wiring changes are needed. The RV-12 already has a large capacitor located in the AV-50000A. I could not find a USA source either. I like WingedFrog's suggestion of using the radiator duct as a source of cooling air.

I checked with those guys and they told me that currently they do not ship outside of the EU. I suppose customs regulations are too much for them to bother with.
I like that the device is a drop-in replacement for the Ducati and would not require any adapter to work in our 12s.
The capacitor is an optional add-on if you would like to have a fail-safe 12V power supply in case the battery gives up the ghost completely. I haven't compared every part of the electrical diagram to our wiring but I am pretty confident that it would be indeed a drop-in replacement without changes to the wiring. They strongly suggest not to rely on the airframe to provide a solid ground connection but to run a ground wire from the regulator straight to the battery and to use a good diameter for that wire. That's something that should have been done anyway and would be a good addition in any case. While at it, one should also add another ground wire from the battery to the engine housing to calm down the sensors as some of us have already done.

Sorry Joe. You are absolutely right.
i was refering to the SILENT-HEKTIK. Typo, I meant to type SH, and missed. I was sure that I had empty connection lugs on my Ducati regulator, but I may be mistaken.

The additional ground wires sound like a winner. Not sure that we need the "fail-safe" capacitor, but it is worth considering.............Tom

I thought Rotax REQUIRED the 22,000uF capacitor.......

They do, and all RV-12 avionics kits supplied by Van's has the capacitor incorporated. It is not in the AV-50000... it is in the AV-50001 switch module (or AV-12 switch module for D-180 builders).

I had not looked at the Silent Hektik regulator before doing my last post. After reviewing its specs, I realized that it is specially designed for the Rotax 912. Although it is not commercialized in the US, I added it as an option for those who operate in the EU. As this looks to be the most promising alternative to the Ducati regulator what about organize shipments on our own?

The "L" (lamp) terminal is not used.
Maybe SILENT-HEKTIK would sell outside of the EU if they got a large order from an American company.

The other totally compatible replacement is GR6 from www.Schicke-Electronic.de
who also will not sell to US. Several Europa owners in the UK are using them and there is a LAA approved mod for their use in the UK. A few owners in the US have had UK friends purchase them and send them over here.
