There's a geared re-drive available from an Australian outfit which might fit the
bill for your VW engine. See for a few pictures etc. They used to sell it
as a seperate item in the past. Guess they still do.

Hi Jack,
what an interesting idea that you actually WANT the plane to stall.
Manufacturers always use the fact that a plane will not stall as a selling
point. Certainly having a plane that stalls gently, or just nods and
continues flying is what most pilots look for.
I am sold on the VG`s as without them my Extra would not have produced a low
enough stalling speed to qualify as an ultralight here in the UK.
Have a read your post correctly?

Hi Richard,
thanks for the idea, it certainly looks pretty neat.
I have arranged pulleys in the same configuration as you and as you say it
needs a lot of rope. I have used a larger diameter rope as it is a bit
easier on the hands as I pull the plane over the hump created by a scaffold
tube which runs across the floor of the hangar entrance.
At the moment I have made a rope bridle with the ends just looped around the
base of the undercart legs. I would have preferred to make the attachment
points further towards the tail but with the tail wheel running in a guiding
track this seems to work.
Thanks again
Pat

Hi Larry,
thanks for the pics. Very neat contrivance ( and what neat feet you have
Grandma !).
Your design would be great if I had a flat floor and just a slope to pull
the plane up but I would hesitate to apply to the tail fitting the force
that I need to shift mine.
I built my hangar, some years ago, of scaffold tubes and plastic cladding
sheets and I used for the front an invention called a `Galebreaker`. This
is in effect a loosely woven tarpaulin. Farmers use them to divide up, or
enclose existing barns. They are made to hook on to the upright RSJ`s (You
call them `I` beams I think) and are pulled tight by a ratchet system.
As you can imagine the compression force applied to the side upright
attachment points, particularly when the wind blows, is considerable so as
well as putting the uprights into 40 gallon barrels filled with concrete I
retained the tube at ground level to stop the sides moving inwards.
I should have buried it but the Challenger I had manhandled easily over the
tube with the aid of a couple of v shaped chocks and I just didn`t think the
work entailed was worth it. In retrospect a wrong decision.
At the moment I attach a bridle to the u/c and heave on a pulley system and
with a guide channel for the rear wheel this seems to be working. I will
have another look at the tail fitting as the back is the obvious place to
lead the plane from
Thanks

Your right, the Kolb people are excited about the posibility of the VW engine being
used on the Plane. They made the jig off the vw engine block I took to them
and have already made and power coated my cage. I will be picking things
up probably tomorrow. My engine parts are trickling in slowly. I will be using
the water cooled heads and light weight cylinders. It looks like my total
engin cost will be around 7000.

Pat,
I flew gliders/sailplanes for several years. This was one of the things
that lead me to the FireFly. I like to sit up front for the view. The next
best thing is and if you are going to have an engine, is to have all the
noise behind you. But the neat thing about gliding is the fact that there
is no engine noise or vibration that masks what is going on as the aircraft
slips through the air. Since you are trying to stay up as long as possible,
one must stay in a thermal as long as possible. This is done by slow flight
in a tight bank. You keep your eyes out side and keep pulling back on the
stick until the wing starts to burble and then relax pressure to keep the
wing at maximum lift and just above stall as you climb.
The only reason the FireFly broke cleanly is because I forced it to. The
right wing complained long before the stick reached the stop. IF one
continued to hold the stick centered and back against the stop, the FireFly
would go into a spin. All one has to do is let the stick go forward and the
FireFly starts flying again with very little altitude loss. I consider your
statement "Certainly having a plane that stalls gently, or just nods and
continues flying is what most pilots look for." and apt description for my
FireFly.

I'm trying to shop for a new boom tube for my FS 1 I just broke. I have the plans

be going there for a couple more days. Meanwhile I'd like to find this costly

I'm hoping someone here has the size(5" I know) and specs for the boom tube for
the early FS. I need to know what alloy, wall thickness and overall length.
Thanks, guys.

Morning Thom:
Give Travis a call at TNK, 606-862-9692.
They usually have some seconds on hand that have cosmetic blemishes that
they can not send out with a kit.
I am sure you can get a good price on it that may offset the high shipping

No thanks, Pat. That big tanker was enough for me. He came in about 45
degrees to my left rear and I didn't see him until he passed under. They
normally travel in pairs, too, and sure enough I picked up the other when he
turned crosswind. Quite an experience watching him close. My 31 mph ground
speed and his 300. After that I decided the nice cool air above the
inversion layer wasn't worth it and dropped down into the heat.

Hi Richard
The only thing I don't like in the GP motor is the belt driven design. Its a personal
preference, as I have been told that they are as reliable as the steel
drives. But still I rather have metal transferring the power via a shock absorber.
I am not sure if there is any metal gear box for the VW conversion, but I would
certainly go for one if there was. The Rotax 912s will have no advantage over
a VW with a metal gear box similar to an SPG-2 drive. Rotax has a big advantage
over a Suzuki DOHC because of weight for the total package.
I have not flown my project yet so I can't say if there is a performance penalty
in comparison, but I am sure there will be none with a VW powered unit, because
of the lower weight, and with the GP motor you will have way more HP than
even the Suzuki 1.3 DOHC.
I can always throttle back is my motto, or derate a motor. But if it ain't there,
then I ain't got it. :-)

Well Pat, its a question of how far away from the stall he runs out of elevator
authority. If he can get another 3 or 5 mph before a stall then I doubt he would
want to give up on that, and in ground effect it can be as much as 10 mph
of less speed. So I would certainly want my airplane to give me all the performance
it has. In a short field environment you really do want your LD max at its
optimum, otherwise you lost margins for safe flight, either in climb (VX) or
landing (VFE). Could mean the difference between bent gear, or hung up in a
tree, or just a close call.

In theory I agree with you I would prefer a gear drive. When I first got my
cog belt drive I complained to the guys at Valley about the vibration. They
had some vibration with their wood props but much less than I had with the
relatively heavy PowerFin. The have been working for years on something that
would dampen the harmonic resonance of the VW engine. I know they tried a
few rubber dampeners and later a sprag clutch with less than desirable
results with their cog belt drives. Finally they came out with the one way
slipping belt system that they are also using on their V twin engine. I have
some concern about the life of the belts as I see belt shavings on my engine
case but there isn't any visible wear on the belts. Also the wear indicator
on the drive doesn't show anything after the 15 hours I have put on them.
They sent me a set of belts that they had run for app. 5 hours so that I
wouldn't have to do the after run in adjustment while on the way to Oshkosh.
They have run the belts 100+ hours so far on their air boat so they should
last that long and there test bed airplane is building hours every day. I
think they put 10 hours that drive/plane just at Oshkosh.
Sorry I got carried away but my point is a redrive needs to be tuned to a
engine to get smooth operation. My redrive is a series 3 drive and is the
result of considerable work that is very likely needed on a gear drive unit.
Rotax has the opportunity to use a considerable development budget to tune
their redrive for their engines and just in the last year or so developed
the slipper clutch for the 912S engine.
To put a SPG-2 drive on a VW might be easy but maybe not? What is the weight
on the redrive? What ratios are available in the 1.6 to 1.7 area? What does
the drive cost? Do they have a drive shaft and a mounting adapter for the
VW? Do they have a dampener built in the drive? Do they offer different
dampeners that would allow tuning for the VW or even your Suzuki.
Good luck on that project. We need Rotax alternatives to force Rotax into a
better pricing structure. In fact every one prices new engines around Rotax
prices.

Hi Richard,
they can get you anywhere. Apart from my Harrier experience, I was once
, learning to fly gliders, chased up the launch wire by a Hercules. I
was with an instructor and we dropped the cable at around 1000ft just as
a Herc overtook us underneath.. Just to one side luckily or we would
have dropped the wire into his props. That would have made his eyes
water.
I met a friendthe other day who I had known since gliding days. He too
graduated to ultralights, a Rans, and when I asked him how the flying
was going he replied.
" I have packed it in. Its too damn dangerous" Now I knew that he had
dived into the ground from aroun 10ft when a pin connecting the controls
to the elevator dropped out and he had still carried on flying after
that so I asked what had happened. "A bloody Herc flew under me` he
said. Thats rough I commiserated what height were you? He went pale at
the memory. "I was in the f********n circuit"

Hi Jack,
All pilots would benefit by some gliding IMHO. A 45 degree bank, 5knots
above the stall with 9 or 10 other gliders formating on you within a 200
yard circle is very character building. That plus the knowledge that a
farmers field is waiting for you below....

Hi Boyd,
thanks for the arial info. Digging around I have found a very old marine GPS
which gives lat and long only and is a bout the size of a shoe box. However
to my surprise included with the GPS was about 2 metres of antenna and a
rubber ducky arial complete with connectors. I think that solves the

Assuming the same wall thickness (and not knowing how it ties into the rest
of the structure), the 1 1/4" tubing is only 57% as strong for bending
loads as the 1 1/2". Do you really want to fly an airplane whose wings are
only half as strong as they should be?
Fix it right.

Rick N:
Rotax developed the slipper clutch for the 912ULS primarily because we were
having a hard time starting the engines. Once started, they ran fine.
The reason for the startup problem was the increased compression which shook
the engine on initial startup. This aggravated the float bowls on the carbs
by aerating the fuel. From their things snowballed and the engine stayed in
a "gear chatter" mode.
The slip clutch took care of this problem, along with a high torque starter.
Turned the high compression 912ULS into a kitten.
The 912UL has no requirement for the slipper clutch. Don't know about the
914.
Basic 912 gear box is same as 1989 models.

Im in the same boat as you.
Bought my Ultrastar this month and am patching some hanger rash on the wing and
tail.
I also found a collapsed full rib 1 before the wingtip, so I'll have to cut the
skin to fix it.
I'm wanting to know about any recommended mods for the Ultrastar.
Did you find any info on them you can pass along?

Pat, Back in the Reagan years I was flying at Little Mtn in Mt. Vernon, WA
thermalling just under cloud base at around 3500' and about a half mile
downwind of take off. The wind noise started getting louder and thinking I
was flying a bit fast I pushed out a bit, but that made the inside wing tip
start to buffet so I increased speed and continued the turn. Suddenly there
was an A-7 Corsair II right at my altitude, turning away slightly, going by
close enough that I could read the placards on the side of the fuselage, and
the pilot was waving at me! He was in my blind spot so I thank the Dear Lord
he saw me.
Never owned a glider without bright red leading edges to this day. Even the
trike has bright red leading edges, although the fuselage is only bright
yellow. You can never have too much visibility. I'd sure like to know if
that 135 driver saw me or if it was just dumb luck.

Ron, Where the 912 has an advantage over the VW is weight, about 60 lb.
worth. Those Austrian engineers went to great lengths to keep the engine as
light as possible. And if your talking about the 912S your giving up 20 HP,
too.
I like VW's a lot and as a child of the 60's I've owned my share. I even
owned a "Thing", and the Vanagon is on my favorite vehicle list since my son
looped one on Hwy 80 with me sleeping in the back, but I've walked into VW
parts depts carrying the latest broken bit and singing the "Volkswagen, does
it again" commercial jingle too many times. Maybe all the development work
has solved some of the problems, but I've lost the #3 exhaust valve head on
type 1, type 3, and type 4 engines and they don't run worth a darn on three
cylinders.

I sent a E-mail to the EAA and they forwarded my E-mail to the head guy
in the Ultralight area and this is his response. My interpretation of
his response is go away and leave me alone. Anyone else want to give it
a try? If we sent a bunch of messages maybe we could get something done.
His comment that they wouldn't even consider porta potties or trash cans
in the area is a standard that only applies to the Ultralight area as
there are trash cans and porta potties on the edges of all the GA
parking.
If they really do roll that area they don't have a clue of what they are
doing.

Rick,
Thank you for the e-mail and for your participation at AirVenture. Your
feedback is important to improve the event for the future.
Because the ultralight aircraft parking and camping area is inside the
fenced operations area of the ultralight runway we would not consider
placing a port-o-let or trash can inside the fenced runway operations
area. In the ultralight camp ground there were port-o-lets and a trash
dumpster for campground use to include your use. The shower facility
you mentioned serves the ultralight campground and the Vintage aircraft
camping south of the ultralight area.
Thank you for the suggestion about rolling the ultralight runway. Over
the years of using this runway we have done this and it does seem to
help, so we will continue this in the future.

For the forth year I have flown into Oshkosh for AirVenture and have
attended since 1981. I fly my Kolb MKIII into and camp at the ultra
light strip. Please in the future would it be possible to locate a trash
barrel and may be a porta potty to serve this campground??? There is a
shower at the far end of the sea plane parking could it be relocated
closer to were the people are?
Also some day it would be nice to roll the runway and camping area.
I maintain a grass strip and know that once rolled it will stay
relatively smooth for years. It has been 15 years since I rolled my
strip in Michigan and it is considerably smoother.
I don't know exactly what is happening but the attendance in the
ultra light/LSA area in general is way down (camping,spectators and
venders) from previous years. I hear many complaints from vendors that
they can't afford your rates. The ultra light/LSA community is going
through tough times right now and may need a price break. I saw a bunch
of grass roots ultra light vendors that introduced updated true ultra
lights at Sun N Fun that just couldn't afford to attend AirVenture.
Remember AirVenture is there to serve everyone not just the high
rollers.

No one with dial-up wants to tie up their phone line to "read" e-mail.
They all want to down-load their mail ,,,,,, then read it off line.

Hello gang,
A about 2 weeks ago I reported a request for suggestions on a engine
problem I had experenced. I sort of thought is was fuel related. Here is what
it did. I replaced the pulse pump with a new one, replaced the fuel filter,
installed a 3 amp battery, new key west regulator, elecl fuel pump plumbed in
series. Did away with the primer bulb and bypass. I also installed new plug
wires even thou the mags checked out ok....they seemed to be quite old. So
here is the results....engine starts better than ever. elec fuel pump works
excellent for filling carb. bowls. I use a primer for getting some gas into the
engine...I have pull start. After starting I run engine with elec. fuel
pump off to make sure pulse pump is working and on take off I also use elec.
pump ...when i got about 1000 feet agl i turn off elec pump and she keeps
running just fine....have put about 3 hours on engine with no hicups...Life is
good, flew up to a fly in last Sat at Purdy field here in Michigan. ....some of
the other Kolb guys were there, Rick Nielson with his Mk lll with the VW
engine on it....Steve Spence with his new MK3X that has a 100hp rotax....a very
nice Kolb....and looks to me like Steve is a good pilot, he sure is a lot of
fun to talk planes with. At any rate we had a good time and Rick flew
formation with me part of the way home...I am a bit slow for his plane however.
Thanks again for all the suggestions you guys to good...

Why don't you call Vassily up there in Canada, he will be happy to talk to you.
Mention to him that Ron from Arizona suggested that.
I have not weighed the SPG-2 I think its on the heavy side, I am estimating it
to be around 30 pounds if not a bit more. It ain't light, it is about as tough
as they get, its over built.

In theory I agree with you I would prefer a gear drive. When I first got my
cog belt drive I complained to the guys at Valley about the vibration. They
had some vibration with their wood props but much less than I had with the
relatively heavy PowerFin. The have been working for years on something that
would dampen the harmonic resonance of the VW engine. I know they tried a
few rubber dampeners and later a sprag clutch with less than desirable
results with their cog belt drives. Finally they came out with the one way
slipping belt system that they are also using on their V twin engine. I have
some concern about the life of the belts as I see belt shavings on my engine
case but there isn't any visible wear on the belts. Also the wear indicator
on the drive doesn't show anything after the 15 hours I have put on them.
They sent me a set of belts that they had run for app. 5 hours so that I
wouldn't have to do the after run in adjustment while on the way to Oshkosh.
They have run the belts 100+ hours so far on their air boat so they should
last that long and there test bed airplane is building hours every day. I
think they put 10 hours that drive/plane just at Oshkosh.
Sorry I got carried away but my point is a redrive needs to be tuned to a
engine to get smooth operation. My redrive is a series 3 drive and is the
result of considerable work that is very likely needed on a gear drive unit.
Rotax has the opportunity to use a considerable development budget to tune
their redrive for their engines and just in the last year or so developed
the slipper clutch for the 912S engine.
To put a SPG-2 drive on a VW might be easy but maybe not? What is the weight
on the redrive? What ratios are available in the 1.6 to 1.7 area? What does
the drive cost? Do they have a drive shaft and a mounting adapter for the
VW? Do they have a dampener built in the drive? Do they offer different
dampeners that would allow tuning for the VW or even your Suzuki.
Good luck on that project. We need Rotax alternatives to force Rotax into a
better pricing structure. In fact every one prices new engines around Rotax
prices.
