All,
Still watching the UL. The Jab was such a disappointment, advertised
the same low price, ease of maintenance, price advantages, etc.. It has
been disappointing watching the early engine buyers painful lessons.
The Jab has some improvements and bears watching. I am watching the UL
with great hope, as I know many are. Even the high power UL has a
limited prop diameter of 64 inches, higher than expected fuel flows, a
large drop off in torque above 2400 RPM, a high rev requirement to
produce it's 130 horses and an unknown amount of ducting and tweaking
necessary to cool.
Of course I have a love hate relationship with everything on an
aircraft. I have found dependability, reliability, maintainability, and
ease of installation are all considerations first, then price. You get
what you pay for, not what you hope for. Right now the big UL is the
price of a 912S, or so, I hope it stays that way. I am really looking
at a couple guys I have met with UL engines to see just how the UL is
working out, right now they have huge inlets and much ducting and
instrumenting. Needs a high speed climb to cool so far on one.
Flying is believing, anything else is rubbish.
Just my dumb opinion, I'm getting cranky in my old age. I have the
right, as my 914 is one of the oldest models and has had to go through
it's problems, ADs and worries. The new 914s are a gem, but just like
my RV owner friends, all engines need growth and have issues, even
Lycomings.

Why not Go all the way and check out the UL-Power engine instead?
Bet the spare parts are very reasonable if compared...
That will be my future choice!
Cheers!

Fellow Rotax owners:
Having worked with Jason Parker on the SDS setup, I am not surprised
by the requirements, electrical, fuel and air will change.
Eric's wedding takes precedence over the review of the new manuals
for this week.
Concerns I have, like you:
ECU will be proprietary you can bet. Dealer only settings etc.
Rotax will have a special class on it you for sure.
Plumbing will be tight with two pumps and revised air intake.
I had hopes they would use an engine driven pump but if it needs
dual alternators, one can bet it is dual electric pumps.
Are the pumps in the fuselage only, and now must we contend with
40 psi fuel in the fuselage. Quite the hazard.
Are the pumps designed to be in the engine compartment. which is
safer in a crash if proper fuel shutoffs are included.
This would allow a retrofit to any kit without changing normal
Rotax plumbing.
Rotax is not keen on making things retrofitable, so I doubt any
of us current owners will benefit. I hope I am wrong.
I know that putting the Jason Parker setup with turbo fuel
injection didn't warrant the cost as it would be years to get payback,
so learn to service the carbs was my opinion.
Many more questions abound, but I will patiently wait for a proper
manuals and documentation review.
Damn, just as I really got proficient with the dual bings and could
make them sing, another thing to go wrong and have to learn how to fix.

Better than the press release, the Install, Operators, and Light
Maint Manuals are up on the ROAN site.
>From a quick perusal:
Looks like it will fit under the Europa hood with the new steel
air box
sitting on top of the engine.
No description of the new engine/panel instrumentation based on
the CANbus interface to the ECU.
ECU requires a dongle for service - Is this a dealer only device?
Two alternators built-in to the engine now with automatic rollover
for failure on one to keep the dual fuel pumps turning.
Manuals have altitude power performance chart now, but not fuel
consumption with altitude. From claim about 10% improvement in
consumption, I'll bet the EFI reduces richness at altitude better than
the
Bing 64s
No word yet on update kit to existing 912s
Looks like something to check out at SnF later this month
