Harley powered airplane

[Brett]

I built a Zenith 601 XL with a Harley motor. It took about 7 months to
build alot of that time figuring out the motor stuff. Then 3 mo.
waiting for the inspection. Well I just got my inspection done on the
9th and I took it up. WOW what a rush. You can see it at

Nice ad. Nice movie.

Looks torquey. How much rudder on takeoff?

Also looks to be an installation where the cylinder head temps should be
monitored and maybe the cylinders should be baffled. Love them Harleys,
though. Evo runs much cooler than the shovel-head or panhead.

Interesting... Aside from the belt drive, is the motor stock??? What
prop is used? Custom? At what RPM is the engine going to cruise )


It appears you plan on basically assembling Zodiac XL kits, fitting the
Harley motor to them, and selling the complete airplane.... Here, I
believe, many of us are perhaps interested in the firewall forward
package, if not just the engine and/or belt drive. What is your pricing
for those options???

I assume this will only run on 91+ octane mo-gas... do you know if 100LL
would run this baby properly? (hard to find mo-gas sometimes on cross-
countries)?

Looks really cool, and the aaahhh factor of having a Harley Plane is
hard to ignore. It will be interesting to see the long-term performance
of this baby. I'm either going to build a Zodiac XL or a Sonex...
either of which may be ideal for this type engine... I will not even
begin construction for 6 months to a year, so I will be following your
progress with interest.

Hmmm........... I particularly like the caption on the picture of the

In motorcycle circles, aren't Harleys known more for their nostalga
and styling and less for their power to weight ratio?

Jay,

I agree with you on the style vs. power to weight, but a Harley does
have the advantage of "loosing" the transmission and just using the
engine as a direct drive. The PSRU would put the Harley into it's
power range so that ain't too bad either.

USAF used to use 2 Moto Guzzi V50 (500CC) engines on their prop
driven pusher-puller design ROV in the late 80's. I saw one up close
at a small field near the Arizona - Mexican border. Same idea, lose
the gearbox and put a GM alternator to power all the toys in the
baggage section.

No, they are known for having to have a ute (and a trailer cause there will
be more than one!) follow the ride to bring home the broken ones. Unless you
count the fancy new motordesigned in Germany they have a typical TBO of 400
hours.

Every Harley I know, is in pieces more often than it is riden.

Hope this helps,
Peter

Oh, they're known for their power to weight ratio - it's lower than
just about any other bike (with the exception of my bicycle of
course).

The old panheads were not designed for durability. Neither were the
shovelheads. The blockheads, or evos, last longer, run cooler, have more
power to weight because they are much lighter -- with aluminum heads and
cylinders. I put 30k trouble-free miles on an 89 Evo before selling it to
a German for more than I paid for it new. So it's a good investment too.

I stopped once to help an old-timer from Loozeeanner replace his clutch
cable on a '69 shovelhead. He said the engine had over 80k miles on it and
all he had repaired on the engine was the clutch. The clutch cable we
replaced had been working for him since new. He also said he had gotten 20k
miles on an o-ring chain. He had bought his Harley new.

Who makes motorcycles in your country, and do you have a quality assurance
report to make on them?

Proud owner of a shovelhead and a panhead, both of which do fine and are
well-maintained.

Well the answer is quite easy, the power supplies in TV's have large
capacitors in them. All Harley TV's need to do is under rate them so
they will blow every now and then. This will spray the inside of the
set with OIL, nice smelly stuff. It will leak out all over the place
just like Harley owners desire.:-)

I found, it's a pity to hide such a beauty among engines below a cowling.
Could you imagine an nostalgia aircraft, with the Harley motor on the nose
without any cowling, taking of in formation with a number of Harley drivers
in Oshkosh?

It has a good bit of tourqe on take off. Just a bit of rudder.
We will be offering motor packages ranging from 80 hp to 115 hp.
But we won't sell any until I am done testing and I am satisfied with
the results. So far it I am very pleased. As for this motor it is
stock. I wanted to see how that worked first. Then from there the
power will only go up.

Three days out of hospital and roaring to go for a Merry Xmas and
Happy NY. May not last out '04 but will start out with a big bang <G>

My Indian leaked oil. Do think that is where HD got the idea?

You talking about the V-Rod engine? That's from Italy, not Germany. The
HogAir pictures look like an Evolution engine to me, with some mods.

Did they take it out to Kill Devil Hills and fly it today? I mean today
being The Day, and all.

Todays the day here and if they try take off on the hack, will be in
about 4 hours +/-.

Sorry Al, but "a certain organization" secured an exclusive contract for that
gig a few years ago. There could have been nearly three dozen Wright type
machines in KH for "the day", but um, well...

A friend of mine is starting an Epps 1924 monoplane project that may get
powered by H-D. And I may eventually bet around to building an even older Epps
plane with a similar powerplant.

You mean something like this?
<http://www.hillfamily.org/david/aviation/Epps1924/Epps1924p01.htm>

Original was powered by an Indian Chief engine. Current front runner
for the replica is a Harley Evo, though Brett has convinced me to at
least consider a Twin Cam motor olike he's using.

LOL,

I was wondering when you would enter this thread David. BTW, find out anything
interesting about the air Hawg? Pricing on it and the PSRU?
