I think it makes sense, Lowell and Thor. Fishing rods are made of long glassfiber
and epoxy, aren't they? They seem to flex well, without braking. If I was to
design one, I think I would go for an even bow of 45 degrees, instead of a sharp
bend. Somehow, I feel a bend is an invitation to a stress area.
Cheers,
Michel

With the Jabiru, my model 3 is 530 lbs dry, Kirby. If you add 160 lbs for myself
and maybe 70 lbs for half tanks, it comes to 760 lbs, hardly a heavy plane,
I think. And since the stall speed is proportional to the square root of the weight,
I don't think our 30 lbs difference should mean that much.

Well, apparently it does, with my Jabiru and the air outlet scoop that really sucks
like hell, ahead of the firewall. I think my firewall is not really airtight.
But you mention your pitot tube being 10 degrees up. Mine is about ten degrees
down from the wing cord. As Kurt says, the angle should be about half of the stall
angle. Are your sure your pitot pointing up is not giving you a lower speed
reading?
Cheers,
Michel

Michel, Yes I agree the pitot tube could be giving a incorrect
reading. Will try to bend it down and re test this week. And perhaps
the static port issue might be giving reading off a bit as well. To
me if consistant, that is all i need. But to make comparisons we all
needto be on a equal platform.
By the way, what is yout opinion on the Droop tips? I would rather
have the extra lift and slow flight handling and lose a few mph cruise.
It no fun coming into 500 foot strips with too much speed. :)
I got a friend putting a monnet VW 85 hp into his sonex and i am
looking forward to see the performace. I think that is a very cost
effective Kitfox engine possibility.

John,
Do you consider the Tube gear hard to handle on the ground?
I find it quite tame to be honest.
Agree about the hard landings being hard on any gear. Easier to fix a
bent gear rather than a longeron.

Exactly, Kirby. I think we are both off the true speed, each on our side if it.
But who cares? I can feel when my plane is on the edge of a stall, I don't need
to read the ASI. In my case, it is only a bit embarrassing when I am asked
and have to prove that my plane stall speed is under 40 MPH to satisfy the Norwegian
microlight rule.
> By the way, what is yout opinion on the Droop tips?
I have no idea, Kirby. I am only a novice who bases his understanding on what he
reads. I understand that it should give me more lift at low speed since it reduces
wingtip vortex. Other than that, I don't feel it takes much of my vision
and yes, maybe it helps in a ground loop. I read the list and learn from people
who are more experienced.
Cheers,
Michel

I've had a fiberglass spring under a Corvette now for
almost 20 years. Single transverse leaf. Works like
a charm and weighs a fraction of the old multileaf
steel springs. I KNOW 'glass would work for a Kitfox
spring if someone just builds it right.
I'm also interested in more info.

Hi all
I went to the AERO-2005 airshow in Germany last month, there I found a
fiberglass tail spring made by a company from the Czech republic. It looks
good and seams to fit wrealy nice and it is lighter then the double leaf
steel spring I have on today. The only thing I need to change is putting a
little longer bolts to fit it because it is a little thicker then the double
steel spring.
The price was so crazy that I could not resist to buy it.
Have any of you tried out these fiberglas springs ?
Whats your opinion are they better then the aluminum and/or the steel?

I made a Kitfox model for X-Plane, Robert. You'll find it here:
http://home.online.no/~michel/micro/
I have also made (partly) my Kitfox with a Jabiru for X-Plane 8. But it is not
entirely finished. The truth is ... it's funnier to fly the real thing than make
a model of it! :-)
Write to me privately if you want it, anyway.

With all the inputs on this subject can someone give what good setting should be?
I have an IVO CAP and at WOT can get arround 6000 RPM -- My question is what
is ideal ?? Should I set my prop to 6000 @ WOT then throttle back to 5500
for cruise leaving the prop setting alone ?? What does everyone thing are good
numbers to set since with the CAP I can set any RPM I want??

Thanks Kirby. This is surprising to me. The acceleration with the 72"
Powerfin on the 912S really sets you back in the seat when you put the
throttle in. It is just the top end (or lack there of) that bothers me.
There are just too many variables. For instance is the 72" GSC still better
than the 72" powerfin on a 100 hp 912S compared to the 84 hp Verner? Was
the PowerFin prop an "F" version? What RPM's at the prop were achieved with
each engine? And on and on...
I would sure like to try a 2 blade hub with my prop, but they don't make one
to fit the 912S.
Learning as I go....

Kirby
A 72 3 blade Powerfin prop was tested and found to have less thrust
than the 72 GCS wooden 3 blade but was otherwise satisfactory. If
ground and aircraft structural clearance will allow, the 72 props
should provide the best solution.

--> Kitfox-List message posted by: Raystuff7@aol.com
Robert,
I have the aluminum gear legs. All my groundloops were on grass,
fortunately.
I never got a wing tip down. The Fox 6 has the CG about 11 1/2" aft the
axles. The BD-4 has it about
9 1/2" aft. This arrangements makes for easy ground handling. When I turned
the Fox gear legs around, it moves the axles 3" aft, and handles better on
the
ground and also makes it possible to do a good wheel landing. But the level
weight on the tail went from 55 lbs to about 40 lbs. Even though the BD-4 is
500 lbs heavier, it had the same weight on the tail. I believe there is
still
enough weight on the tail to prevent nose-over with a careful pilot.
One of the main reasons I was so concerned with this is my wife likes a
tri-gear airplane, She learned to fly in a Cherokee. Anyway, I have just
completed the conversion, and gone to the trigear on the Kitfox. I bought
the nose
gear assembly and just fiinished the job- it took a couple of week-ends. I
havn't
flown it , but taxied it around. I noticed a big difference in visibility
over the nose, but it sure does seem to bounce around much more on the now
shorter wheelbase.

I added two more sets of pictures to the sportflight files. The first
set is of a plane I built that was parked at a remote Idaho strip where
the only way in is to fly or ride a horse.( this is in the
damage/incident file) They left food in the plane and a bear decided it
wanted it. Luckily the damage was to an area that I could duct tape up
with two layers of tape and fly it home for repairs. It is painted with
urethane paint which we have had discussions about before but it made
the repairs much harder, and if it had been a wing I would have had to
recover the entire wing because you can not glue fabric to urethane
paint in any place that has load. Urethane paints sure makes them
pretty, but our results are mixed with it. Some are having the paint
spider web type crack - not much but it is there, and others are not. It
is not just me as the mixed results are with different painters and
different paints. It seems to crack on impact if it is cold. We had one
person flip his seat belt off when getting out of a plane on a cold day
and where the buckle hit it made a bulls eye in the paint. It is easy to
put on, dangerous as heck, looks good, hard to repair. If you are going
to use and abuse your plane I still think polytone is best. My 9 year
old Vixen with 750 hours looks almost as good as new with polytone.
Urethane paint is great on metal and glass were it does not have to flex
as much. I have painted 11 fabric planes now and still have a lot to learn.
The next set is of the latest plane I finished and it is in the
completions section. It is in testing now with a little less than 30
hours on it. It is made as light as I could make it and it really does
well. It came in at 753 pounds.
I would like to see pictures of what others are doing. It really helps
to get ideas.

I think carbon fiber will have a better weight to strength ratio, Mike. But is
weight so much of a problem? I think the most important factor would be to
mould (carbon or glass) under vacuum. Air bubbles and uneven distribution of
the fiber and resin is, IMHO, a danger for tensile strength.

That is only true with a fixed pitch (or ground adjustable) prop.
The manual for my Piper Turbo Arrow III shows several combinations of
RPM and manifold pressure that all result in the same horsepower.

Just when you think everything's ready . . . Lola has a visible bilateral toe-in
condition. She has the standard tube gear. I put 200# of dead weight in her
and it made little difference. I want to correct this before the FAA gets here
for airworthiness inspection but am more than a little apprehensive about putting
the cheater bar to axle to bend the gear weldment. From reviewing the archives,
it looks like this is more likely to bend the mild steel axle then the
weldment. I'm guessing that a bent axle would likely muck up the disk/pad brake
alignment.
I'd appreciate some details from you guys that have done this and succeeded.
Thanks much.

Randy,
After recieving your latest information...i.e. your ability to over-rev at
full throttle in level flight I will have to say you are not lugging the
engine.
I thought you were only able to get 5500 at WOT in level flight.
I guess we didn't have enough information.
It appears that you being limited to get 5000rpm WOT static rpm yet are able
to over-rev the engine at full throttle in level flight is a combination of
airframe and prop design.
Clean airframes commonly "out fly" their fixed pitch prop. Our Titan does it
regularily. We have to set the prop quite course because the plane is so
clean it will easily outfly the prop.
The propeller design also has a lot to do with the range of prm the engine
operates at.
In short, I'd guess, in your case, the prop design has more to do with the low
static rpm and high level flight WOT rpm.
What WOT rpm to you atain at climb attitude? As long as you don't over-rev in
climb it sounds like you are in good shape.
I hope the above makes sense.

Hi Guys, does anyone on the list know of a ultralight aircraft call a Mentor. It
is a 2 seat high wing with STOL performance that is apparently a scaled clone
of a Maul. The kit is or was developed in the USA.
Thanks for your help
Graeme
