I'll admit to the "limited knowledge" of the Rotax engine, but please
point out the derogatory remarks....I couldn't find them. This is as
close as I came to making a statement about the Rotax ( November 16,
2009 8:13:49 PM GMT-05:00 )
"Not to blatantly bash the Rotax (just subtly), but from what I've
seen of 'em, there is enough wires, cables, hoses and fuel lines to
probably hold the engine in place. I think that's what kept ....was
it Gary's? ......plane flyable, and let him land after one blade
departed and the resultant vibration shook the engine loose. You old-
timers will recall who I mean. I'm pretty sure that was a Rotax
engine. Seriously though, I'm NOT bashing Rotax, but I wouldn't bet
on any amount of the normal wiring, hoses, etc. to hold ANY engine in
place once the vibration of a less-than-complete prop begins."
If anything, I made a derogatory remark about the Jabiru when I said:
"I put one on mine, John, just so I could stop worrying about that
aspect of flight and worry about other things. Of course, I fly
behind a Jabiru, so maybe it's justified. : )"
You said: "Liquid cooled engines are here to stay. Just look out
your car window."
When I look out my car window, I see air-cooled airplanes
flying.....I don't see cars flying (well, not too often, anyway)
You said: I still don't know what the countdown to 1000 means.
It means I am getting near 1000 hours in my homebuilt airplane. I
believe it is pretty self-explanatory. Some time ago, the moderators
asked us to include in our signatures, some info about what Kitfox we
are building, or flying, and what kind of engine, etc. I chose to do
this so that others could see that if they persevered, they will be
flying, too. Some folks call it inspiration. Apparently it sticks in
your craw, otherwise why would you harp on it?
Once I get to 1000 hours, I can get one of those spiffy prop sleeves
from the EAA when I go to Oshkosh, and proudly display it. I don't
see a display of your pride in owning a Kitfox...do you? Or do you
just drop by here while vacationing from building your RV?
You said: "The bottom line is. Do your homework."
I did my homework, built my plane, chose a Jabiru engine because
that's what I wanted in it, flew it across the country, and
apparently the story was good enough to be printed in one of those
"aviation magazines" that you mentioned earlier.
If you'd like, I could autograph a copy and send it your way. : )
