Default S-19 Flies - Decision Time!

The visibility is way better in the 12.

Default S-19 Flies - Decision Time!

One of my reservations about the 12 was the Rotax engine. Saturday, I got a ride in an Evektor Sports Star that is powered by the same engine as the 12. It starts instantly and the engine idles at 1800 rpm and contrary to what I thought, the engine does not sound like it is screaming. Even at max rpm the engine does not sound like it is working hard. It just purrs along and is soooo smooth. I no longer have any reservations about the Rotax. I am looking forward to getting my kit.

As I'm fond of saying, the Rotax is a good engine, just a different one. You eventually get used to checking the coolant as well as the oil before every flight, installing metal foil tape over the oil cooler / radiator in the winter, frequent oil changes with 100LL and - of course - the carb balance routine. It takes no time at all to get used to the simple starting and smoothness. Treat it like the manual says and you'll enjoy it.

One thing that you need to do, though, it design the cowl to allow you to check cooland and oil levels easily. On the CT and Evektor SportStar, you have to remove the cowling to get at the expansion tank (45 sec job, but still). The T-211 Thorpedo uses the Jabiru 3300 engine, but has a large latch for an oil door, maybe 9" x 9", front and center of the cowling. Not pretty, but it makes for simple, quick yet safe preflights.

After many hours of running both carbs and EFI on a 912 on the test stand, I have to say it is a pretty smooth little engine and never sounds strained. It is also very quiet with the supplied muffler- prop noise drowns out the exhaust note.

BTW Doug, I have a flight in the CT scheduled on July 10th, weather and wind permitting, I'll give you my RV vs CT evaluation.

Default EFI

Ross:

I am unware of EFI as an option for the Rotax 912. Is this a product that your business offers? How many are out there running?

It is very quiet with the muffler exhaust. If you use a ground-adjust prop and match the blade pitch carefully, it is amazingly quiet on the ground.

I have flown the CT and a -6 back to back, but I won't bias you with my thoughts; I'll wait to hear yours.

We are doing preliminary studies at this time to gauge performance increases and possible cost of a complete kit. Only one running at this time.

Is anybody else contemplating a Subaru EA-81 or EA-82
based engine?

There's a little company near Akron Ohio (Ram) that is
promising 100 to 140 hp fuel injected, turbocharged
aero engines based on the Brat motor.

Subaru has made an awful lot of the things and they all
conformed to some very demanding Federal emission standards
which require 100,000 miles of operation with minimal degradation
in emission performance and subject to typical American bonehead
maintenance procedures.

Water cooling (cockpit heat), fuel injection, available parts and
support (thousands in service), O/H cam, all aluminum flat 4.
What's not to like? Throw on a gear or Gilmer belt reduction unit
and it's an aircraft engine.

Cool RV-12 Fuel Tank

I would agree that Van's has more kit-planes in the air than anyone. But looking at the photos, and knowing that the wings are removable, and seeing what appears to be a fuel cap behind the right passenger seat really scares me! I want the fuel to be about 2 miles behind me in the event of a crash -- not bathing me with fuel from behind the seat.

Does anyone know where the fuel tanks really are? Look at the photo of the right rear quadrant on Van's website.

I like the fact that the S-19 has fuel tanks about 4' away from the fuse.
