Rotax 582 - great engine in Kitfox - the exhaust was cut to fit in the cowl on
Kitfoxes and you will see about 58 HP only. This helps the Kitfox 582s to last
longer.
583 and 670 are good engines but power band will not be a good cruiser at 5800.
Power band starts over 6200 rpm and will fall off pipe under that.
Hirth-- Time bomb for the most part.

Bob Widmer is all over you tube, great performance engine but not for cruising
and dependability.
I got hundreds of Kitfox 582 and some 912 movies on you tube.

Best tip is build them light to get good performance. The later model and current
at close to 1000 lbs empty. Early ones started at 400lbs or so.
The early Avid A would climb at 2200 fpm plus !!

There were three Kitfox aircraft here locally that I am aware of. There may
be (probably) a couple I am unfamiliar with so far. One (sister to mine) met
with an approach stall I think (it had a very heavy Subaru engine in it)
Details are sketchy because the pilot has no memory of the incident. One
other was destroyed after many hours in a bad float landing, totally pilot
error. The reason I bring these incidents up is that in both cases the pilot
hit their heads quite badly on the cabin structure. This is no criticism,
both pilots survived and one had only minor injury, a major plus for
Kitfoxes IMHO.
The reason I bring it up is to ask if others have padded the tubes above our
heads or if they wear a helmet. I am somewhat tempted to the latter as I
have very little hair and a helmet would provide protection from sun as well
as impact. Anyway, I was thinking about it and watching videos of papilot's
vw Kitfox on YouTube, noticed the pads and got to wondering what others have
done.
Those tubes probably hurt like the dickens and they aren't that far off my
noggin.

A proper fitting and secured helmet is excellent protection, a proven safety devise,
the padding of the tubes will only help with bumping your head while getting
in or out the the plane will provide no real protection in the event of a
accident. A helmet must fit properly a chin strap and a neck nape strap are needed
for full benefits.

Here's a PDF of an old "Kitfox Times" news letter. It does not say when the thicker
walled tubing was used in the landing gear. It does give some specifics
on wing spar and and lift strut carry through tube size and thickness and lift
strut diameter and thickness. The second and third pages are reversed in the
PDF.

Dave, I haven't "tweaked" my 582 . Just attempted to set up and maintain
properly. I don't want to reduce life or reliabilty. My opinion is that a
582 is just about right for a Mod 2 or 3. But, I haven't flown a 912. I
might like it.

One of my test pilots also bumped his head in mine so he suggested
padding, which I did, and just never removed it.
