Kitfoxers, I am ready to mount my 582 that I purchased firewall forward complete. There is a round steel oil reservoir tank with a plastic sight tube. The tank looks as if it has a 1 1/2 gallon capacity. My question is, isn't that an awlfull lot of oil. Are you 582 drivers carrying that big of an oil reservoir tank?

I used to have a Kitfox 3 project with 582 that I never did fix up like I thought I would. It had a plastic oil bottle that
held probably 3 quarts. I ended up with two of those bottles and let only one go with the plane when I sold it.
I just ran out to the garage and measured it and it is 7 3/4" X 5 3/4" X 2 3/4" I snapped a few pics also. It looks kind
of dirty in the photo. I think it was the standard Kitfox 3 tank. Let me know if you are interested in it.

Pat,
My Model 2 came with a plastic tank. I haven't measured it's capacity but it looks to be well under 1 gal. I'd guess maybe 1/2 gal. The engine seems to use about a pint an hour.

A pint an hour Marco?! At what gal/hr rate? Sounds like a thick mix to me, or is mine mixing too thin? My container holds a quart, and I fill it when it gets 1/2 empty (or is that 1/2 full? optimist/pessimist?) which is probably every third or fourth top-off of the main tank (5 gals per top-off = 1 20L gerry can). I get 2 fills out of a quart of oil.
Sounds like another subject that needs some empirical measurements, and I, for one, shouldn't take for granted(?)

Nothing at all empirical about this Bob. I burn "about" 4.5 g/hr in my 582. After a flight lasting "about" an hour, it seems to take "about" 1/2 of a quart to top off the oil tank. Hard to tell exactly as those oil bottles are black and opaque. Next time I fly I'll try to remember to quantify those variables more precisely and get back to you.

I think it depends on what kind of flying you are doing. Remember that the oil pump mixes between 50:1 at WOT to about 100:1 at an idle. Depending on the cruise RPM, prop load, throttle position etc, you may use more or less oil than others, depending on your flying style hour for hour. At a strict 50:1 it would be 1 quart for ever 12 gallons. I bet I burn about 1 quart for every 15 gallons averaged out. This is with the pump set up just as instructed in the manual with the marks lining up at idle.

Ok, getting empirical<g> (in the UK it was called "anally retentive")...
According to my operators manual the Model II with a 582LC gets 2.1 gph at 65 mph cruise, and 3.7 at 85. I recon I burn about 2.5/hr at my usual 75mph which is in line with the specs but I should verify that.
The "Care and Feeding of Your Rotax" manual says the injection pump should deliver between 50:1 and 70:1; which at 2.5 gph (10 quarts/hr) means I should go between 5 hours (50 qts gas to 1 qt oil) and 7 hours (70:1) on my 1qt reservoir bottle-full. My recent Airworthiness Cert test time was 5 hours and I recall topping it up when it reached the half-way mark twice in 6 hours, so that's 60:1, right on the money.
So that sounds about right on my setup - what's different on yours? What's a "582-90"?

582-90 is the mod 90 or the grey head, not the newer mod 99 blue head.
What RPM do you cruise at? I cruise around 57-5800 and figure a 5.5 gallon an hour burn. On floats this gives me about a 75 mph cruise. I can bring it back to 5600 and at 70 mph burn around 4.5 hr.

Pat,
That's an awful lot of oil, which may not be a bad thing. If you can live with the extra 9 pounds when full, and the location, I'd use it. I have the 2 liter Nalgene bottle that Skystar supplied and identical to what Jim pictured and it's theoretically good for about 5 hours endurance at my usual cruise of 4.7 gph fuel and ~0.7 pph oil. The problem with a 2-stroke is that, generally speaking, you have to carry oil for the entire trip wherever you go. When I go on long cross-countries I'll carry as many as 24 pints of oil when I leave. It would be nice to have your 1 1/2 gallon "range" in the tank. I know it's semantics, to some extent, but there will be trips you'll make without adding oil that I have to carry and pour my little pint bottles.
By the way my burn numbers were calculated during long duration cross countries. (~30 hr.) I find I use less oil (~0.5 pph) putting around Ramona, because I spend a lot more time on the ground at idle, percentage-wise.

Hi Len - I cruise at about 5500 rpm and 75 mph, although it's very easy to
slip off that "plane" if I don't hold it trim. When the ASI goes to 65 mph
it goes into mush mode.
I find my Model 2 is *very* susceptible to thermals and often find myself
gaining or losing altitude depending on what's above or below me. Clouds,
fields, lakes, towns, sometime I think even pigeon sh*ts affect the trim.
Ok, I exaggerate a bit... But it's definitely a plane you have to fly *all*
the time!

Guy C Thanks for the advice. I will use the lighter plastic bottle. I can't envision taking a trip that would use that much oil and I don't mind carrying a qt or so to add. That said C converting from 912 to 582 C if I run into a weight and balance problem of too light in the nose the additional oil capacity might be the answer C but I hope not.

At 4 gal/hr fuel usage a pint an hour would be 32:1 mix. About what one would estimate.
I would size the oil reservoir so that you could go on a typical long trip where you
would need to buy fuel to return without having to carry additional oil or buy it. So
let's say for example you go on a trip someplace that is a half day away of about 6
hours and before returning you top off your fuel tanks. Total flight time of 12 hours
would use around 45 to 48 gallons of fuel and that would require 1.5 gallons of oil.
If that is not your typical long range usage model, then size it accordingly. Another
way would be to start with the fuel capacity. Say it is 15 gallons. Then if you allow
for 45 minutes reserve, at 4 gal per hour that is 3 gallons reserve and you have a net
usable of 12 gallons or 3 hours. Topping off the fuel (without adding engine oil) and
returning home would use another 12 gallons. Total fuel burn of 24 gallons and the oil
tank would need to have capacity to mix 24 gallons plus 3 reserve gallons or 27 total
fuel. Assuming a 32:1 mix then the oil tank would need to have a 6-3/4 pint capacity.
So if you size the oil tank much smaller than a gallon, then you'll probably need to
carry spare oil some of the time.
Make sense?

It would make sense at 4 gal/hr and a 32:1 mix, but the model 2 (and 3) with
a 582 is rated at a gas-guzzling 3.7 gph at max cruise of 85 and a more
realistic 2.1 gph at 65; my experience being about 2.5 at 75. And the oil
pump has to be set to deliver a ratio of between 50:1 to 70:1, or it would
be out of spec.
That puts your numbers below Paul at a factor of 3 to 4 times higher than
actual consumption. I would not use that to determine the size of the
plastic tank and I certainly wouldn't rely on a large tank to influence your
C of G Pat - implying that you would go tail-heavy as you run low on oil!
Just my humble and well-intentioned opinion...

I don't know that mine's set up any differently. I adjusted it per the book. At 140 hrs, it runs great and the plugs look like just they're supposed to. I'm interested in how you get a 582 to average a 2.5 g/hr fuel burn. Now that's atypical.
A 582-90 is the "gray head." The "blue head" is a 582-99.

Ok, getting empirical<g> (in the UK it was called "anally retentive")...
According to my operators manual the Model II with a 582LC gets 2.1 gph at 65 mph cruise, and 3.7 at 85. I recon I burn about 2.5/hr at my usual 75mph which is in line with the specs but I should verify that.
The "Care and Feeding of Your Rotax" manual says the injection pump should deliver between 50:1 and 70:1; which at 2.5 gph (10 quarts/hr) means I should go between 5 hours (50 qts gas to 1 qt oil) and 7 hours (70:1) on my 1qt reservoir bottle-full. My recent Airworthiness Cert test time was 5 hours and I recall topping it up when it reached the half-way mark twice in 6 hours, so that's 60:1, right on the money.
So that sounds about right on my setup - what's different on yours? What's a "582-90"?

Nothing at all empirical about this Bob. I burn "about" 4.5 g/hr in my 582. After a flight lasting "about" an hour, it seems to take "about" 1/2 of a quart to top off the oil tank. Hard to tell exactly as those oil bottles are black and opaque. Next time I fly I'll try to remember to quantify those variables more precisely and get back to you.

A pint an hour Marco?! At what gal/hr rate? Sounds like a thick mix to me, or is mine mixing too thin? My container holds a quart, and I fill it when it gets 1/2 empty (or is that 1/2 full? optimist/pessimist?) which is probably every third or fourth top-off of the main tank (5 gals per top-off = 1 20L gerry can). I get 2 fills out of a quart of oil.
Sounds like another subject that needs some empirical measurements, and I, for one, shouldn't take for granted(?)

Kitfoxers, I am ready to mount my 582 that I purchased firewall forward complete. There is a round steel oil reservoir tank with a plastic sight tube. The tank looks as if it has a 1 1/2 gallon capacity. My question is, isn't that an awlfull lot of oil. Are you 582 drivers carrying that big of an oil reservoir tank?

It certainly sounds atypical from all the posts I have seen here, but it is spot on to what it says in the Owners Manual.
Here's some facts:
The engine was purchased in 1989 so I assume that is a "gray head"
It went for about 600 hours before a complete rebuild
It is now a little over 200 hours since the rebuild
I have the optional ground-adjustable GSC props and I think the "B" reduction gearbox
My weight-and-balance shows an empty weight of 525 lbs
With me and typical fuel = 732 lbs
When I am solo I rarely go WOT, 6000 rpm has more than enough power, max rpm is posted as 6300
I typically cruise at 5000-5500, descend at 4000, idle at 3000
I *never* use flaperons for trim, I have a horiz stab tab that works great. I know one time I did a short-field takeoff and cruised for a while at 1 notch of flaps, I had a *lot* of trouble maintaining cruise and was no doubt burning a lot. Personally I think my model 2 is light, fairly clean (no added fairings no), and trim. Now if only I could say the same for myself!
Personally I was a bit worried I was running a bit lean, especially with water temps high recently. But since the burn rate is exactly on spec and the temp gauge/sensor has actually failed I am not as worried.
Spot anything there that might make the difference?

I don't know that mine's set up any differently. I adjusted it per the book. At 140 hrs, it runs great and the plugs look like just they're supposed to. I'm interested in how you get a 582 to average a 2.5 g/hr fuel burn. Now that's atypical.
A 582-90 is the "gray head." The "blue head" is a 582-99.

Ok, getting empirical<g> (in the UK it was called "anally retentive")...
According to my operators manual the Model II with a 582LC gets 2.1 gph at 65 mph cruise, and 3.7 at 85. I recon I burn about 2.5/hr at my usual 75mph which is in line with the specs but I should verify that.
The "Care and Feeding of Your Rotax" manual says the injection pump should deliver between 50:1 and 70:1; which at 2.5 gph (10 quarts/hr) means I should go between 5 hours (50 qts gas to 1 qt oil) and 7 hours (70:1) on my 1qt reservoir bottle-full. My recent Airworthiness Cert test time was 5 hours and I recall topping it up when it reached the half-way mark twice in 6 hours, so that's 60:1, right on the money.
So that sounds about right on my setup - what's different on yours? What's a "582-90"?

Nothing at all empirical about this Bob. I burn "about" 4.5 g/hr in my 582. After a flight lasting "about" an hour, it seems to take "about" 1/2 of a quart to top off the oil tank. Hard to tell exactly as those oil bottles are black and opaque. Next time I fly I'll try to remember to quantify those variables more precisely and get back to you.

A pint an hour Marco?! At what gal/hr rate? Sounds like a thick mix to me, or is mine mixing too thin? My container holds a quart, and I fill it when it gets 1/2 empty (or is that 1/2 full? optimist/pessimist?) which is probably every third or fourth top-off of the main tank (5 gals per top-off = 1 20L gerry can). I get 2 fills out of a quart of oil.
Sounds like another subject that needs some empirical measurements, and I, for one, shouldn't take for granted(?)

Pat,
My Model 2 came with a plastic tank. I haven't measured it's capacity but it looks to be well under 1 gal. I'd guess maybe 1/2 gal. The engine seems to use about a pint an hour.

Kitfoxers, I am ready to mount my 582 that I purchased firewall forward complete. There is a round steel oil reservoir tank with a plastic sight tube. The tank looks as if it has a 1 1/2 gallon capacity. My question is, isn't that an awlfull lot of oil. Are you 582 drivers carrying that big of an oil reservoir tank?

|
|
If the cylinder head is natural metal colored (gray) it's the model 90. If the head is blue it's the 99.
I don't have elevator trim so I use the flaperons instead. I realize this makes an already draggy airplane draggier still but it's simple and I have no complaints about the flight characteristics or engine performance other than the relatively high fuel consumption (and low TBO) which is typical of two strokes. Someday I might install a trim tab if it will save fuel at cruise.
WOT my 582 yields about 5800 rpm on the same prop you're swinging, so your'e pitched a little finer. My empty wt is 535, with me and typical fuel (10 gal), TOW is about 750. Climbs out at 1000-1100 fpm (WOT) with egt's at 1050-1100 degrees.
What are your egt's running? How do your plugs look?

It certainly sounds atypical from all the posts I have seen here, but it is spot on to what it says in the Owners Manual.
Here's some facts:
The engine was purchased in 1989 so I assume that is a "gray head"
It went for about 600 hours before a complete rebuild
It is now a little over 200 hours since the rebuild
I have the optional ground-adjustable GSC props and I think the "B" reduction gearbox
My weight-and-balance shows an empty weight of 525 lbs
With me and typical fuel = 732 lbs
When I am solo I rarely go WOT, 6000 rpm has more than enough power, max rpm is posted as 6300
I typically cruise at 5000-5500, descend at 4000, idle at 3000
I *never* use flaperons for trim, I have a horiz stab tab that works great. I know one time I did a short-field takeoff and cruised for a while at 1 notch of flaps, I had a *lot* of trouble maintaining cruise and was no doubt burning a lot. Personally I think my model 2 is light, fairly clean (no added fairings no), and trim. Now if only I could say the same for myself!
Personally I was a bit worried I was running a bit lean, especially with water temps high recently. But since the burn rate is exactly on spec and the temp gauge/sensor has actually failed I am not as worried.
Spot anything there that might make the difference?

Bob C Thanks for the advice. I guess I could go tail heavy if I let the level get low and should use a perment fix if my weight and balance need it.

It would make sense at 4 gal/hr and a 32:1 mix C but the model 2 (and 3) with
a 582 is rated at a gas-guzzling 3.7 gph at max cruise of 85 and a more
realistic 2.1 gph at 65; my experience being about 2.5 at 75. And the oil
pump has to be set to deliver a ratio of between 50:1 to 70:1 C or it would
be out of spec.
That puts your numbers below Paul at a factor of 3 to 4 times higher than
actual consumption. I would not use that to determine the size of the
plastic tank and I certainly wouldn't rely on a large tank to influence your
C of G Pat - implying that you would go tail-heavy as you run low on oil!
Just my humble and well-intentioned opinion...

The cylinder head is gray, so it's a model 90. I believe the "blue head" didn't come out until 1991-92 and mine was flying by then.
Hard to believe that using flaperons for trim would increase drag that much, although I know as soon as I pull on the flap lever the nose tips down a *lot* (the difference between seeing the runway and flying blind) and I have to add power. I can also reset the trim tab for neutral stick - only with full flap does it not trim out but at that setting it's like having air brakes.
How much flap do you need to add for trim? How does it fly with no "flaps" - nose up or nose down? Maybe it's basically tail-heavy and you need to add flap (ie drag) to fly level? As you add speed the nose tends to pitch up, so you add flap(drag) to counteract? Sorry so many questions but I have never used the flaps for trim so don't know. The PFA (oversight for UK KF builds) issues a build document that basically says using flaps for trim is bad, and describes the elevator trim installation instead.
I don't have EGT gauges but should probably look into that, I feel left out.
I changed the plugs and wires not too long ago and haven't checked since, should be about due. I had to change them for a different type because the plug wires had a tendency to get loose. I will inspect the plugs after fixing the water temp gauge and reserve warning sensor light problems are fixed. What's the ratio on these things - 15 minutes of repair per hour used?  Almost as bad as a chainsaw!

If the cylinder head is natural metal colored (gray) it's the model 90. If the head is blue it's the 99.
I don't have elevator trim so I use the flaperons instead. I realize this makes an already draggy airplane draggier still but it's simple and I have no complaints about the flight characteristics or engine performance other than the relatively high fuel consumption (and low TBO) which is typical of two strokes. Someday I might install a trim tab if it will save fuel at cruise.
WOT my 582 yields about 5800 rpm on the same prop you're swinging, so your'e pitched a little finer. My empty wt is 535, with me and typical fuel (10 gal), TOW is about 750. Climbs out at 1000-1100 fpm (WOT) with egt's at 1050-1100 degrees.
What are your egt's running? How do your plugs look?

It certainly sounds atypical from all the posts I have seen here, but it is spot on to what it says in the Owners Manual.
Here's some facts:
The engine was purchased in 1989 so I assume that is a "gray head"
It went for about 600 hours before a complete rebuild
It is now a little over 200 hours since the rebuild
I have the optional ground-adjustable GSC props and I think the "B" reduction gearbox
My weight-and-balance shows an empty weight of 525 lbs
With me and typical fuel = 732 lbs
When I am solo I rarely go WOT, 6000 rpm has more than enough power, max rpm is posted as 6300
I typically cruise at 5000-5500, descend at 4000, idle at 3000
I *never* use flaperons for trim, I have a horiz stab tab that works great. I know one time I did a short-field takeoff and cruised for a while at 1 notch of flaps, I had a *lot* of trouble maintaining cruise and was no doubt burning a lot. Personally I think my model 2 is light, fairly clean (no added fairings no), and trim. Now if only I could say the same for myself!
Personally I was a bit worried I was running a bit lean, especially with water temps high recently. But since the burn rate is exactly on spec and the temp gauge/sensor has actually failed I am not as worried.
Spot anything there that might make the difference?

I don't know that mine's set up any differently. I adjusted it per the book. At 140 hrs, it runs great and the plugs look like just they're supposed to. I'm interested in how you get a 582 to average a 2.5 g/hr fuel burn. Now that's atypical.
A 582-90 is the "gray head." The "blue head" is a 582-99.

Ok, getting empirical<g> (in the UK it was called "anally retentive")...
According to my operators manual the Model II with a 582LC gets 2.1 gph at 65 mph cruise, and 3.7 at 85. I recon I burn about 2.5/hr at my usual 75mph which is in line with the specs but I should verify that.
The "Care and Feeding of Your Rotax" manual says the injection pump should deliver between 50:1 and 70:1; which at 2.5 gph (10 quarts/hr) means I should go between 5 hours (50 qts gas to 1 qt oil) and 7 hours (70:1) on my 1qt reservoir bottle-full. My recent Airworthiness Cert test time was 5 hours and I recall topping it up when it reached the half-way mark twice in 6 hours, so that's 60:1, right on the money.
So that sounds about right on my setup - what's different on yours? What's a "582-90"?

Nothing at all empirical about this Bob. I burn "about" 4.5 g/hr in my 582. After a flight lasting "about" an hour, it seems to take "about" 1/2 of a quart to top off the oil tank. Hard to tell exactly as those oil bottles are black and opaque. Next time I fly I'll try to remember to quantify those variables more precisely and get back to you.

A pint an hour Marco?! At what gal/hr rate? Sounds like a thick mix to me, or is mine mixing too thin? My container holds a quart, and I fill it when it gets 1/2 empty (or is that 1/2 full? optimist/pessimist?) which is probably every third or fourth top-off of the main tank (5 gals per top-off = 1 20L gerry can). I get 2 fills out of a quart of oil.
Sounds like another subject that needs some empirical measurements, and I, for one, shouldn't take for granted(?)

Pat,
My Model 2 came with a plastic tank. I haven't measured it's capacity but it looks to be well under 1 gal. I'd guess maybe 1/2 gal. The engine seems to use about a pint an hour.

Kitfoxers, I am ready to mount my 582 that I purchased firewall forward complete. There is a round steel oil reservoir tank with a plastic sight tube. The tank looks as if it has a 1 1/2 gallon capacity. My question is, isn't that an awlfull lot of oil. Are you 582 drivers carrying that big of an oil reservoir tank?
