OK...like I said...it was just my 2 cents worth.
I <thought> I was very careful not to 'bash' the Rotax in my message...or
start misinformed rumors...that wasn't the intent of my message.
That's just what I remembered from my one ride...maybe the prop was pitched
too flat...or the tach was wrong...and that is possible because they had
just replaced the engine the day before...
Sorry if others were offended too!

Tim,
Don't know what kind of Rotax was in that Kitfox, but it sure
wasn't a 912 - they have a max. rpm of 5,800 on takeoff !!
The 2 stroke Rotaxes are high maintenance, and have a relatively
short service life (about 250 -300 hr. TBO) HOWEVER -
The 912 is one GREAT ENGINE !!!
I had lots of years behind Lycomings, Continentals, Jacobs,
Gypseys, Rangers, etc. .... When I first got to try the 912. Like
most people, I was worried about the high rpm, and the re-drive, and ...
I was very fortunate - when I first got to fly it, it WASN'T
MINE - I treated it carefully, but, if it blew up - well ... it was
insured, and they could just come & get the pieces !!
I flew it around for about 50 hours - it ran quiet, smooth, and
burned about 2 gallons/hour in the cold February air !! Then Anna &
I flew it from Toronto down to Florida - damn thing just kept on ticking !!
It loves to cruise all day at 5,400 rpm - not even working hard !!
Anyway, I became convinced !!! We have flown that 912 all over
North America, and the total maintenance so far, other than oil changes,
with filters, at 50 hours, has been 3 sets of spark plugs, and 2
new air filters !!! Not too shabby for over 900 Hours !!!
Having put about 1,100 hours on my other Rebel, with a Lycoming
O-235, which burns 6 gallons/hour, and a quart of oil every 6 hours,
I can compare the maintenance. The Lycosaurus has had:
One complete TOP overhaul, 2 mags, 2 carburetors, 2 exhaust
systems, and 2 new cylinders - so far !! This on top of horrendous
gas & oil consumption (by comparison !) !!
When I bought it, the 912 was about $7,800US - not bad for a
BRAND-NEW ENGINE, with MODERN engineering & metallurgy !!
To each his own , but I will defend the 912 - it has been THE
BEST ENGINE I've EVER FLOWN BEHIND !!! ===
==== ====
Just wanted to squash any misinformed rumours before they spread !
......bobp
The O-320 will give you dazzling performance, and you'll just love
your Rebel - but be prepared to spend the bucks to KEEP it running !!
(Something about ... "you pays me now, or you pays me later" !!)
Lycoming - the gift that keeps on costing !!

Hi gang:
Ammo for the cannons...just to add my 2 cents worth...
I considered a Rotax and Jabiru when I started thinking about engines three
years ago....I just felt at that uninformed time that I did not want to
spend big money for a 50 year old technology airplane engine...surely there
was something more acceptable...
I flew a Kitfox 5 with a Rotax 912 when I was choosing a homebuilt....but
something about the 7,000 RPM on takeoff and 5,500 in cruise bugged me too
much....plus the water-cooling thing worried me. Also, as I recall, they
are high maintenance...and there is a lot of information about maintaining
them and the frequency of maintenance in the Kitfox forum....
Finally, I decided that if I was going to spend the big money, I was going
to do it on a 'real airplane engine' (sorry Dave Bangle...I do like the
Subaru Legacy engine...but I did not want to engineer the firewall forward
myself due to the increase in build time...)
Finally, I just cratered and purchased a 0 SMOH Lycoming O-320-E2D. Built
by a guy here, and I watched the whole process. About $12,000 US with
accessories. All parts within new limits.
For me, it was a value for money decision.

I checked out the prices on
www.rotec.com - YOWEEEEE !!! I'm
rushing out now to buy a lottery ticket now, too !!
I guess they 'un-bundled' the exhaust, intake, and engine mount
to make the price look more 'reasonable' !!!!
Looks like I've got to go rethink my plans again, too - I still
think the 912-ULS would be a good engine, and the fuel & maintenance
savings over the lifetime would make it less expensive than a new
Lycoming, BUT - that's a LOT of money !! (about $24,000 CDN - after
all parts AND taxes !!) The bare 912-ULS is $17,325CDN - about the
cost of an overhauled O-235 or O-320 !!
.....bobp
And the search for a GOOD, CHEAP engine continues .....

Will have to check that out - my understanding was that the price
for the 912-S SPECIFICALLY included the exhaust system (because it's
specially balanced), AND a ring type engine mount (which still needs
legs welded to it to go to the firewall ! The radiator is just a
standard V-W Rabbit rad - no need to buy the overpriced Rotax rads !!
The 914 has NOT had a good history - heard of a few that have
suffered broken cranks (including one at Brampton - on a Zenair 601)
It has also been reported to be fiddly to keep running well - it sounded
like a good idea, but if it really WAS working well, I think we'd see
a LOT more of them, even at that aweful price !!
At the moment, the 912-UL-S looks like my first choice, but time
will tell ....
Perhaps Tom Inglis (Tiverton Tom) will have a pilot report for us
soon, on his 912 Rebel.... At the moment, the regular 912 does
what I need.
