I have read thru the archieves and still dont really know if I would be
better off with a warp drive prop on my sling shot or not. I have a 582,
three blad IVO on it now with an E box and about 1 1/2 " of shim behind the
prop to bring it away from the ails. my buddy has about the same exact set
up, 2.62 gears in his C box and flys circles around me with a 68' three
blade warp. Now, my plane is a little heavier but he is physically heavier
so that cant be all that. I have my engine mounted probably an inch or so
higher than his so I can fold the wings. that might be some of it but he
drinks way less gas and climbs like an bat out of hell and suffers no take
off lag. Is it or could it just be the warp is just that much better? what
say you kolb gouls? these are both new blue heads and our temps are almost
the same. ted cowan, alabama.

Ted,
The faster UL's such as your SS will do better with the warp.
I like Ivos for the FF and FS, but not for the SS. I tried Ivos on both the
582 powered SS and the much faster 582 powered Laser and the Ivos are
definitely not as fast. The Laser suffered more speed loss than the SS - the
faster the aircraft the larger the speed loss with Ivo. (Now I am referring
to the smaller x-section Ivo blade; had no experience with the larger HP
ivos.) If you want to out run your buddy, put on a 2-blade warp. But I'd
stay with the 3-blade warp for smoothness.

Ted,
Here is an idea: Exchange props for a day or two and see what happens to performance.
Then, let the rest of us know.
In my experience, there is little or no difference in performance between the Warp
and the IVO.

Hi Ellery,
Did you sell your engine before you took it off the plane ?
Somebody on the list said that's the best way to do it,...people can see
there's nothing wrong with it . (except high time)
Nothin like headed out with a low time engine...I'll bet John's gonna
do some big hops after he puts in his new 912...
Gotta Fly...

Do you also have 2.62 gears like your buddy does? If so, try taking off one
of your three blades (It doesn't matter which one... <grin>) and making it
a two blade Ivo. Prop if for about 6250 rpm at 50 mph on climbout and see
what happens top end. If that doesn't work, follow Dennis Souder's advice
and buy a 2 blade Warp. And let us know how things turn out.

Best thing to do is ignore 90% of what you read on the internet about
overhauling at 300 or 400 hours...& a lot of other B.S. Most of these statements
are
made by armchair bullshitters with nothing else to do but sit at their
computers spewing bullshit...and I don't give a crap what the owner's manual says.
I've worked both 503s & 582s for the past near 30 years. Worked them very,
very hard towing hang gliders & doing aerial photography. Wide open, full
throttle, slow speed tows from 3,000 to 5,000 ft. The Kolb I use for aerial
photography goes wide open to 15,000 ft.
The Kolb is a low time 503 with about 270 hours on it...a mere child. The
Edge X 503 I have is at 230 hours...another baby.
The Tukan 503 I have for fun flying & towing is closing on 1,500 hours. I
plan to take it to 2,000 hours & beyond. I've topped it only twice in the last
8
years. It could use a top now but still runs fine, still tows gliders &
banners at full throttle.
The 582 I had on a previous Maxair had over 1,000 hours & the biggest mistake
I made was overhauling that one. When we decided to overhaul it, we turned
the motor up-right in order to swing a wider prop. We neglected to turn the oil
reservoir which supplies oil to the crankshaft. I had 3 or 4 engine failures
before we figured out what was wrong.
I've used Pennzoil & a clutch on all aircraft except the Kolb. The Kolb I'm
anxious to see how far it goes without a clutch. Do NOT be afraid to run these
motors wide open. They love it, revel in it & are made for it.
IF IT AIN'T BROKE...DON'T FIX IT.
Now you'll get to hear from all the armchair bullshiters telling you to
ignore all the above.

I got 708 hrs so far on mine - 503 dual carb,
but I think the 503 is tougher than a 447.
And I already know you're not supposed to do that.

Hi Bill C:
Looks like you have a lot more experience with ultralights and two
strokes than I do. I haven't owned one since 1993, when the 582 that
powered my mkIII seized. Yep, at about 220 hours. Must not have been
running it hard enough. ;-)
Anyhow, with limited experience with the 582, 220 hours on mine, and
some time with factory mkIII and SS powered by the 582, I am not
familiar with the "oil reservoir which supplies oil to the crankshaft"
you mention reference you "3 or 4 engine failures." Could you explain
that system for me please.

Maybe this is what he is talking about on overhauls and crankshafts:
"If I were to write it for the 447, it would be 600 hours and it would be
closer to 900 hours for the 377. I'm one that thinks the 300 hours is about
right for the 582 though. If you have had the opportunity to look at
various crankshafts in 2-stroke engines of this size you will notice that
the lower rod area on the Rotax crankshaft has much less slop side to side
and less of an area for lubrication to make it into the bearing. The 377
and 447 have a slit on either side of the lower rod, but the 503 and 582
only have a slit on one side.
Since the time has been put on fast, you have been able to go that long
but even engines that get time fast like that are probably likely to need
at least some attention by 500.
If I was the one writing the TBO for the 503 I would put it at 450 because
that is about where I start seeing crank failures even with well kept
engines."

John,
The oil injection pump depends on gravity flow to feed the pump.
When he changed his engine from a plugs down configuration to a plugs
up configuration without relocating the oil reservoir he no longer
had enough height to gravity flow the oil to the pump when the oil
level in the tank went down some.
At least that is my take on what he wrote.

Just took off my fuel pump fittings that were sealed with teflon tape, and carefully
cleaned off all the tape. I'm now using the Permatex product.
I sometimes wonder just how many butts have been saved by the generous sharing
of knowlege on this list. My thanks to everyone - I've learned a lot here!

I assume he is referring to the oil reservoir which is plumbed to the center
section of the crankcase, housing the crank part that drives the water pump
and the rotary valve. Picture here -
