Why, yes. Stuff it into stifling hot compartment, add a Fetters
re-engineered cooling system, Fetters' pipe, Fetters' carb jetting,
nail the throttle, and it's all good.

Answered in last post to Morgans.

Remember, Rotax's 100% isn't Fetters' 100%, those are two different
100%s. In fact, Rotax had to ask Dennis Fetters to please help them
design their engine. Dennis himself said that, so we know it is true.

Yes they did. Rotax sent me the first water cooled 532 in the world, and
I was the first to get it to fly. Even after, I was the one that was
making the Rotax water cooled engines work the best and coolest.

My cooling systems were working so well, and other manufacturers were
having so much trouble that Rotax started having them call me to help
diagnose their problems. Later, Rotax changed its cooling methods and
temps to run the engine to the same as mine, which I had been doing two
years earlier.

So what's your point?

Rotax did not WANT to be your engine supplier. They were coerced, you
threatened them.

You know dan, it blows me away to see you acting like some righteous
person here. You got one of the biggest blow-hard mouths I've ever seen.
You have verbally victimized so many people here it can't be counted.

Go sell crazy somewhere else.

I've been punched in my nose before too, and deservedly so I might add.

Holy cow, you throwing rocks around?


Dan? Blowhard?

Well, as Bugs would say, "Whadda maroon"...

Oh, I know, you-know-who has an answer for that one, too.

You bet I do, after all, I know what I'm doing, and done it a lot.

Sock puppetry?

not a problem with the engine, but the installation. 98% of all Rotax
engine failures are due to improper customer installation...

.... into the wrong helicopter. The same engine was okay when installed
into a CH-7


The Mini-500, as well as all helicopters that use any reciprocating
engine, run at full RPM, but that is not full bore, since a helicopter
reduces or increases its power setting to operate."

Keep the questions coming!

The PEP pipe narrowed the powerband, and when the engine "falls off" the
pipe, it ain't coming back again. Lawn Dart time.

That was what we were going to use as a prototype, but as I said
Cicare didn't do what he agreed, so even after I advertised we were
going to use his CH-6 as a prototype, that was when I assumed he was
going to live up to his part of the deal. He didn't, and I ended up
having to design the Mini-500 all by myself...


... and golly gosh what a coincidence, it came out almost just like a
CH-6 but I really designed it all by myself really.

Any moron with half a brain can plainly see that there is a world of
difference between the Mini-500 and the CH-6 if they have seen both of
the workings and designs of each aircraft. Why can't you see that?

CH-6 was open cockpit, open engine bay, wide open for your inspection.
The half-brained will be fooled by the MD500 styling, which was your
contribution.

Cicare says they are different, and I say they are different. Now both
designers say they are different, so why is that such a leap for your
pea-brain to wrap itself around??

Two helicopters came out of the CH-6:

The CH-7, a winner by all accounts.
Anyone not seen the picture of one lifting off carrying two more
people standing outside on the skids? Anyone like to?

Don't be bashful.

I've seen two videos of them crashing, one appeared to be of a pilot
performing low-level idiocy and running way short of the bottom half
of a loop before the ground came up and smashed him. He walked away,
likewise the other CH-7 video crasher.

The CH-7 is a fine helicopter.

Yes, well, it doesn't have your fingerprints on it.

By adding the
PEP system, we discovered that it reduced the exhaust back pressure.

That makes no sense. You decided to change the pipe for no apparent
reason, and then discovered the effect?

normal Rotax exhaust system was creating to much back pressure for
helicopter use,

How did you already know that? You discovered the PEP reduced back
pressure after you added it, so what were you trying to accomplish by
changing pipes to begin with?

With the PEP, we only needed to jet it once, and there were no more
issues of people seizing the engine for simply forgetting to change from
summer to winter jetting. The point is, you need the PEP system. Before
the PEP exhaust system became mandatory for the Mini-500, the major
problem of seizing the Rotax could have completely been avoided.

Could have been avoided by Rotax's refusal to supply you engines.

We discovered that the normal
jets that come with the engine for propeller use would not work for
helicopter use.

Jeezus, you ****head. Cicare could have told you that and saved you the
exercise of killing customers.

It was explained why the jets needed to be converted
many times, but it is unbelievable how many owners refused to change the
jetting, which would definitely seize the engine. It got to the point
where we opened the Rotax box and removed the jetting, so that the
owners would have to apply the proper jetting. After doing that, the
engine seizures were reduced to only people refusing to change from
winter to summer jetting. The mandatory PEP did salve this, and there
were no more seizures after it was installed, except for people that
refused to follow the mandatory AD to

There was no mandatory PEP and no mandatory AD. You know that.

The CH-7 Angel did not go to the trouble of fabricating their own
exhaust, but since it was basically a factory built flying aircraft,
they would install the proper jets and needles themselves, and test
flies the aircraft.

Your story makes no sense. Obviously no POS PEP was ever necessary.

Also the Angel was so expensive, that the only
customers that could afford them were already accomplished helicopter
pilots with more skills, and flying a factory built aircraft already set
up properly after construction, compared to the Mini-500 owners where
76% of them were not helicopter pilots, and/or had less than 50 hours in
helicopters when building and flying their Mini-500."

You always knew who you were selling to.

Same Rotax engine, but necessary styling dictated that the engine be
enclosed. Famous for seizing.

You REALLY don't know what you are talking about. Here is what I posted
about the Mini-500 Cooling System:

"The Mini-500 uses a fan powered directly off the engine, not the rotor
drive system, so in that way it will not rob power during an
autorotation.

So what? Cicare chose Fiat radiators and electric fans. Same Rotax
engine, and your installations were seizing, not his. Why was that?

...

(All diagrams deleted)

The Mini-500 was suffering from frame cracking that was occurring behind
the transmission. Please take a look at the first drawing, and you will
see that location marked with a green X.

Why don't you write answers that make sense? Do you think that
copy/paste with "All diagrams deleted" and then telling us to look at
that location marked with a green X means anything?

What we finally discovered was that there were two different forces at
work causing the problem;

First, was the two-per-rev that was being produced in forward flight in
a motion that tended to rock the rotor system, mast and transmission
unit back and forward, as seen in the first drawing at letter “A”. This
action was occurring about 1100 times a minute and was transmitted down
the mast following the blue line, and then horizontally out to the two
arrows pointing up and down on each side of the transmission, which
indicates the direction of force translated on the frame in those areas.
This is not normally a problem, but in the case of the Mini-500, I
designed the frame improperly where this load was focused on the green X
in the first drawing, where the load was being translated into the
center of a tube. Notice that there is a bracket on that tube tying it
into another tube, but this just transmitted the loads to be expelled at
letter “C” in the center of another unsupported tube.

Second, we discovered that with each firing of an engine piston, the
drive belt was pulling down on the transmission large sprocket, as seen
in the first drawing with red lines and letter ”B”. This was hammering
at around 13200 a minute, and that force too was transmitted through the
transmission, and then through the frame and unloading on the area
marked by the green X.

That is way the frame was cracking. Now it needs to be fixed, but the
problem is that there are over 300 Mini-500 shipped that all need a fix.

No, the problem is that Cicare is gone now, you F**Ked up the frame to
fit the required styling, and your customers are already abandoning you.

We were shipping 5 to 6 complete Mini-500 kits a week. Designing and
building a new frame to send to everyone was out of the question,
because I could only build one frame a day, and that was just enough to
keep up with production.

You were way over your head.

Sure, I could have taken a month and duplicated my welding fixtures and
doubled my welding staff, and built two frames and day. But then owners
would have to wait up to a year and a half before we could send out over
300 frames. No, I needed to come up with something that didn't cost the
customer $4800 and took over a year to receive, and whatever it was it
had to work and solve all problems at one time.

Sounds desperate.

That is when I came up with a system that would take the loads from the
two-per-rev, capture the force where it was generated, and distribute
those loads into the hard point in the frame that was all supported
through triangulation. This can be seen on the second drawing following
the blue lines. Notice that the blue line that represent the direction

Hello? Are you talking to us, or doodling pictures somewhere else?

of force across the tube where the green x was is no longer there. I was
successful to take all strain away from the problem area entirely. The
engine pulsing vibration was also handled the same way, along with an
added rubber isolation system on the transmission and up inside the mast
support, and with a new idler arm that was spring loaded.

By coming up with this fix, it not only solved all the problems, but
improved overall balancing of the rotor system, and the fix could be
manufactured fast and affordable. Although this was a major problem that
took some time to identify the cause, dream up the best solution,
prototype and test and finally produce and ship, before or after, no
Mini-500 had crashed due to a cracked frame."

Ok, so there was the problem, and that was my solution. Why do you still
bellyache about an old problems that was solved? Its not the first time
a helicopter had a design flaw that needed fixed. So all the Mini-500
owners and I got over it, why was it your problem, and why are you
complaining about it?

Keep those questions coming!! Its great you are helping me get the real
facts out there!

Amazing.

...

Yeah planemanman, man, I like this part

I am a professional, and feel that I have
always portrayed myself as one to this news group.

OK, All the technical questions have been answered and the facts put
forth for those that wanted to know.

I looked over all the responses to my answers, and didn't find even one
single intelligent response that needed another answer. We are now down
to the few morons here that ran out of arguing with intelligent
responses or questions, and they are now fighting back with the only
real weapon they have ever had... meaningless insults flying out of
their big mouths.

Reminds me of a tribe of little pigmies frantically running around all
screaming at the top of their little lungs at the same time, and only
able to poke their spires at someone's ankles.

Most excitement these dying newsgroups have seen in years. I'm sure the
repercussions will last for even a day or so.

My work here is done. So long losers.

No, we just bore easily with hearing empty heads like your rattle.

The history of the Mini 500 has been written. Right or wrong, neither of you

Both of you really need to get over it, or take it up on email.

What's this "WE" stuff, Tim.

You have made exactly 4 posts (under this name)

I doubt "WE" think of you as part of "US".
