KIRK JENKINS
after 4 PLUS years and used as a doghouse..
"Started right up"
I don't know what you guys call the holes that the air comes out to fill
the Skirts...
But
I noticed that there was more air flowing out the back holes then the
front....Is this normal??
Another question ....There is a gear transfer box behind the motor to
the prop..Does this require oil??
Thanks
Kirk Jenkins,
Ken Roberts
i'm not the scat guy, but just in case you're watching the group waiting for a
quick answer i can help with the gear box thing.
the gear box needs lubricant. it also needs to not be full. there's a certain
level that gear boxes need, and a certain type of lubricant. most use a really
heavy stuff called gear grease. weight depends on application.
if your box is like a car differential, then there's usually a hole for
filling, and when grease flows out of that hole then it's too full. the amount
of air space above the hole assures you're not overfull.
this is usually a low maintenance item. lots of folks go through years of
owning their cars without realizing there's grease in a differential, or
knowing they have a differential. this is for the rear-wheel-drive ones, or
4x4. the front wheel drive ones have a differential too, but it's the
transmission and shares that oil.
as for the holes the air comes out, i can't say if it's right or normal for
more air to come out the rear holes but i can say it's predictable. the rear
holes are closer to the fan, so there's less plenum to slow the air down.
ok, vocabulary:
- duct, fan, you know that.
- splitter: a division in the duct that scoops air from one purpose for
another. in your case, the splitter scoops thrust air and diverts it to
the cushion.
- plenum: the inner chamber of the hull that has the lift air going through
it. the air duct that is between the splitter and those holes.
- holes: feed holes, i think. i'm not using your sort of skirt, so i don't
have them.
- drain holes: separate from the feed holes, they let water escape from the
plenum in your case. other crafts (like mine) have drain holes just like a
regular boat, that let water escape from the hull when you park it.
- skirt: the finger-shaped flexible thingies that cover those holes. in
scat lingo, they are frequently referred to in the plural: skirts. in bag
skirt lingo, there is only one skirt, so it's always singular. unless you
have a nonstandard craft with more than one bag skirt.
- cushion, bubble, etc: I don't think there's an official word for the high
pressure area under the craft. there are lots of words people use for
that.
- hump: when you're on water and not moving, you're digging a hole. that
hole is exactly the size of the hole a boat would make sitting in the
water. the water that is NOT in that hole weighs exactly as much as your
craft. When you start moving, you're trying to crawl out of this hole. if
you move faster than the wave can, then you "get over hump" or exceed hump
speed. the same thing as a boat planing out. planing out works as a
hovercraft term too.
- wake: yes, you have one. it's just a lot smaller than a boat's would be
if you're significantly over hump. the faster you go, the less visible it
is. if you're going fast enough, the wake is not detectable, if you ignore
the change of wave patterns from your skirt dragging over the top.
ok, i'm done typing for now. time to take a nap. have fun.

Thanks for all your input Ken...That is VERY helpfull..
I need all the help I can get when it comes to this foreign object
called the "Scat Hovercraft...lol
I was just looking at the hull and it looks like there is a small crack
on the very back of the aluminum stringers on the left side ...
I am going to do what Doug "The Scat Man suggested and put a lap of
fiberglass mat under neath..
Question:
Why is there more space for more fan blades on the fan??
should i look into getting more blades?
Question:
Should i be concern about ANY kind of holes on top of the craft ,where
there at one time had brackets for something and now there gone and just
small holes where they were once mounted?
Thanks

that fan is used not just in scats, and not just in hovercrafts. it's a
commercially available fan that can be configured for a wide range of engines
by changing the number of blades and the pitch of those blades. in other
words, if you change the number of blades you'll have to get a bigger engine.
> should i look into getting more blades?
no. learn to drive that thing as is. i have personal experience regarding the
advisability of learning to drive an overpowered hovercraft. it tends to thin
out the wallet.

small holes on a hovercraft is the same thing as no holes, unless they're in a
spot where normal use would make them big holes. like on the bottom of a bag
skirt. screw holes in fiberglass, if i understand you correctly, will make
zero difference.

you should paint "the dog house" on that thing, and maybe a little dog house.
maybe a snoopy doing his red baron thing. looks to be about as good a
signature as you could get.

I'll do That...lol....
Thanks again... :)

fan needs only 6 blades ; Scat used 12 blade hubs but it only takes 6 blades
to adequately load the motor and absorb the available horsepower.
On my site there is a word document for each of several
subjects , basic Scat info , fan tuning , etc. , etc..
What "aluminum stringers" do you refer to ?? If you refer
to the under-side of the craft , those are commonly called "skids" or
"runners". These are wear coverings and can be replaced ........ready made
replacements are available at http://www.aircommander.com . However ,
knowing what I have learned over time ; I'd suggest getting up with Dave
LaCombe (who monitors this group I believe) . Any-way I'd suggest replacing
the aluminum with Kevlar felt and epoxy , if you add a couple layers the
wear properties are excellent and it will minimize the hard hull clearance
lost to the surface due to protruding objects below the hard hull (or in
this case the "skids").
The small holes on top can be filled with rivets or small
plastic bolts to avoid air loss from the plenum , but structurally speaking
there's no danger. What it comes down to is it's a matter of choice but not
neccessity.

Man, I got to tell YOU GUY"S....!!
I have NEVER " learned so much about a hobby toy sitting in my carport,
and ME sitting in my living room with my webtv."IN MY LIFE"!!
I can't wait to get home and read some more Info....
I was just telling my wife this.
After a Scooter ride around the little town of Kilgore Tx,...
I traded out a Carpet Cleaning job For two Scooters....Thats what i do
for a living I owne and... Manufacture, my own floor cleaning equipment
and Clean carpet for a living ...How about you guys???
The carpet cleaning BIZ of Manufacturing and cleaning gets so BORING""
What do some of you do for a living??
I really enjoy this Group....
Marquis Songer
also. Ken Roberts is a computer programmer, Doug Pendleton works for the
railroad, Ralph Dubose is a medical doctor of some kind, a few others are
engineers and there are even a few students that hang out every now and
then. I've only touched on a small minority, but as you can tell we are a
pretty diverse group of people.
Best regards,

The other Doug here who told you to forget all you knew about driving
boats. Glad to see you're moving right along with your
obsession......no wait, HOBBY! Yeah, that's it. Don't forget to check
out the HoverLovers group on Yahoo. Bunch of us there, too!
BTW, to answer your question, I manage hazardous materials and
emergency preparedness for a two hospital health care system.

Are you the guy I talked to the other day??
If you are, you really showed me some pointers ............Thanks again"
P.S I always think of what you told me about the weight of one or two
people in the Hover...
Question;
It says 350LBS or persons Does this Make it a Scat 2??
KIRK JENKINS
attention I guess....
"Hey..... good luck with the radiation treatment...
Keep us up to date :)
P.S....I thing the railroad is very interesting...We have a train go buy
our facility 4-5 times a day ....I once clocked it at about 45-47 MPH
driving next to it going down the road with three engines...Another
thing ...A man told me that the engines are powered by generators that
power electric motors to all the wheels...Is this correct???
hoverflyte
it to a minimum:
No that is not quite correct , close but not quite. The diesel
engine turns a huge generator , this creates about 600VAC ; that goes
through a humongus rectifier that changes it to DC . That in turn is used to
run "traction motors" , which are a combo huge DC motor / transmission and
axles with steel tires (of course).
That's the basics ; like I said let's leave this discussion
alone and stick with hovercraft.

only the load capacity of the craft and has nothing to do with the model.
There are several differences between the Scat 1 and 2 the
biggest being the outer hull type . The Scat 2 uses a ABS outer hull and
almost all of the Scat 1 use a fiberglass outer hull. If you visited my site
and read the Scat history thingy you now know that the Scat company had
"model cross over" troubles . They had left over inner hulls but had to use
the ABS outer hull as that is what they were going to. Hence a few Scat 1's
were produced that have an ABS outer hull (not many but a few).
Another difference is the drive system ; the Scat 2 have
gearbox drives where the Scat 1 has a belt drive.
There's 3 basic styles of Scat 2 / 9.5' and 12' . The third
style is a HP . These were the same basic craft but had a beefier engine.
All the Scat models have similar manufacturing based flaws regardless of
length or model . As explained on my site there are several improvements
that can be made but not all are simple , but some are indeed quite easy
fixes depending on what the "defect" is and what fault is being discussed.

Not sure if you have us confused. I'm Doug B. and gave you pointers
on control, and registration of your craft. Doug P. is the resident
ScatMaster and was helping you with your skirt problems and Scat model
info. If you really want to be confused, our middle intials are also
similar, and sound alike. However, I drive a 12T4, Doug P. has a
soon-to-be-sold Scat.
