Default Maintenance costs RV-9A vs RV-12

Bigger motor, a little faster, sucks more fuel. Less efficient for flying around the patch, payload is about the same... What am I missing about comparison of operating costs and insurance? I see many RV-9A's for sale, with steam gauges... Cost to upgrade to glass like a Dynon D1000 touch or ?

I would say that 50mph is more than "a little faster". 100 lbs vs 75 for baggage is also not insignificant. Not sure about comparing operating costs as I have never owned a Rotax but the costs for my O-320 are very reasonable, and parts are easy to find almost anywhere.

For trips around the patch and local flying, a 12 is perfectly suited, and even the occasional XC. More frequent or longer XC's would certainly favor the 9.

Panel upgrade costs depend on who does the work. If it's you, its the cost of the avionics, new panel, etc. If you hire it out, you can probably double that, if not more.

Hah, when I fly side by side with my Rv12 friend I’m burning about the same amount of fuel....but I can go much faster, higher and carry more in my 9A. The only different is I am usually burning 100L and he is burning auto fuel.

And in some places, as on a cross country, auto fuel (mogas) is hard to find without going into town. Update: All I was saying was that if the "other guy" in that post is burning auto gas, he might have to be careful where he lands on a cross country if he wants to continue to use mogas. Hey, I'm a fan of the 12.

Bear in mind, the RV-12 does not require MOGAS. It is optional. Burning AVGAS some of the time, or even all of the time, will affect maintenance frequency and cost, but it's not a problem. There are RV-12s being operated on 100% AVGAS.

I like the RV-12. It's a fine airplane, within its design limits. If it fits your requirements, it's a great little airplane. Having said that, if I were not limited to flying with Sport Pilot privileges, OR if those privileges extended to the RV-9, I would almost certainly be flying an RV-9. The RV-12 has better visibility, at least downward. The RV-9 has more speed, more baggage space (never mind weight capacity), and is a little more rugged. And you can put an engine in it that can burn MOGAS if that's a factor for you.

Yep, you said it. I am burning autofuel as well, and you can't do this in a 12. Midland, TX to Hot Springs, AR in 2:38 last weekend.

That's a tailwind of 56 kts... gettin a little help there, headed 054, gonna pay for it when you head back home. How much motor and HP are you running in your bird?

You asked about the difference between the airplanes, not about headwinds and tailwinds. I'm getting better than 22 nm/gal TRUE in that photo at 149 knots true, at 17,000'. That's what my 9A can do, and I still have a ton of drag cleanup to complete.

The two planes are not the same - they each have niche to fill. Different pilots have different missions. Pick the plane that fits your mission and fly it.

Coming from an RV-9A owner who just took his first RV-12 ride yesterday, this is definitely true. The additional visibility afforded by the 12 is very nice.

Apparently the Roncz airfoil wing likes 17,000 feet. Nice!
