[RCSE] Re: Electric Tug

[Dieter @ ShredAir]

The problem that we've been having so far is putting 2.5
horsepower through a belt without it delaminating, though even that 
problem should be solved quickly.
For the record, getting 2.5 HP continuous is no problem with the 
Reisenauer 6:1 Motor Chief gearbox and a 22-sized Lehner motor. 
Please feel free to contact me for more details.

Title: Re: [RCSE] SuperStands, 'A Must Have' item for
keeping



I got mine
at Vislia years ago and its still serving me!

I saw the versions that Tom has and they are improved.  The
stand has less metal which makes it a lot lighter in the
Sportube  and probably draws less attention in the Xray
check:-)

It sounds like the guy who makes them, life is changing and he is
bored with making them so you'd better hurry up and get one of group
Tom got.

Gordy


Gordy, et al.

The one you got was made by Fred Guilfoyle, after in 1999, I
asked him to make some for us (see how small the world is?). Fred
made a bunch, and when his job situation changed, stopped making
them. Then, Paul Kmetko asked permission to develop them and have
them produced, which we accepted happily. Paul has vastly improved on
our original "just-for-your-buddy design," and they are
better than ever and will continue to be available, no worries... For

Re: [RCSE] A dumb question

Can someone explain a bit about how the wing rod works ?  Has there
been any incident of wing panels detaching from model gliders in the
air ? I am yet to witness one. I know it works , just don¡¦t
understand why .


Unless there is flutter or severe turbulence, flying loads will
prevent the panels from separating on a well-built and well-fitting
plane. We still secure with tape for looks and extra peace of mind.

Re: [RCSE] Micro Slopers?

[Dieter @ ShredAir]

Don't worry about the HS-50 actuating two ailerons, especially if 
they're on torque tubes, which mostly cancel out loads. If you want 
something all done, consider a VIP pylon racer; it's molded to fit 
the HS-50. I fly mine on the slope with all the electric "junk" 
installed and a folding prop. They're fun!

Dieter Mahlein
http://shredair.com

I have two HS-50 servos I can't use for anything right now, and want 
to build something SMALL to use them.  I fly slope mostly so a HLG 
isn't really my cup of tea right now.  I was thinking something of a 
micro sloper with a 30" or less wingspan, standard tail (elevator) 
and one aileron only (so as to not overload the hs-50).  Does anyone 
have any input on something like this?  Have any of y'all done it? I 
know the easy answer is a small flying wing, but I want something 
more 'classic' (for lack of a better word)

I looked up a couple online and wasn't too impressed with the 
available offerings.

I have had no response to this question so I am trying this again.

I have a question about the modules in the vision.  My Vision has a module
with identifying numbers as follows:

93782  72MPCM

FCC ID AXY9MHATXO15

I know this is good for my Vision.

I came across another Module and although the pins are the same there are a
couple of differences.

First the labels are upside down in relation to pin location compared to the
first module.

Second, although the part number is identical (93782), the FCC ID is
different. It is FCC ID AXY ATXO26.

THIRD DIFFENENCE.  THE FIRST HAS GREY CASE AND SECOND HAS BLACK CASE.

Is this module compatible with the vision?  Is there a reason for the
different numbers and color?

Thanks for any help

Re: [RCSE] How does a water ballast system work?

[Dieter @ ShredAir]

Hi all,

I asked about this a while ago on the scale exchange, and didn't get a
response. I'm wondering if someone wouldn't mind explaining how a water
ballast system (mainly for scale models) works.

Is the system pressurized? Do they typically incorporate a diffuser to
disperse the water stream?

Thanks in advance,

The ones I've seen in models are a gimmick, mostly. The problem, it 
appears, is that you can't scale down the viscosity of water. Maybe 
add soap...? That'd look cool:  a plane blowing bubbles on final...

True. Im no aero dynamicist either, and certainly downward deflection 
of airflow at partially-deployed flaps reduces effective breaking. -- 
The main issue for me is that flap deflection between 75 and 90 
degrees adds only 4 percent more frontal area. To me the extra strain 
required on servo, linkage, and hinge is not worth the last 15 
degrees of deflection.

You may want to consider building a larger rudder instead. Twisting

Hello Dave et al.,

I've always assumed this airfoil was by Norbert Habe (and it still 
may be), but it's not on his site at http://www.habebert.de.  -- 
Well, it's a TLAR airfoil for a floater, and as Paul Naton 
demonstrated before the San Diego Mid-Winter Electrics, the plane 
could "stay up all day." He had to land because the tx battery was 
low.

As Al posted, it also did quite well in the windy, squally conditions 
I flew it in in San Diego. I could have stayed up for hours slope'n 
the tree line behind the vendor tents, had that not required to 
continuously break all sorts of a safety rules.

By the way, our website lists an incorrect price (I'll have Marcela 
fix that tonight); the Cumulus costs $495. We have 2 in stock and 3 
coming.

Ed, I do beg to differ. That's NOT the way it is. As an importer, it 
takes no more than a phone call to the manufacturer to get at least a 
CG range. I write  basic manuals for all our planes, and the 
recommendations in there -- while conservative, as Daryl pointed out 
-- will get the plane safely in the air and let every pilot "adjust 
to taste" on their own.

I am happy to not be perpetuating the myth that high-performance 
planes are only for experts who know everything already. Given just a 
little guidance in the beginning, many intermediate pilots will find 
out how easy and enjoyable it is to fly a good plane, and it will 
sharpen their skills quicker than a not so good one.

Happy Holidays!

Nonono, you got it all wrong... :o)  All you need is a single long 
berm kinda like a dam, with round sissy LZs on either end. Mount the 
thing on a big turn table, and have a small wind vane feed a 
computerized motor which automatically turns the berm perpendicular 
to the wind.

Now you can BS (ballistic slope'n) and DS to your heart's content.

Improve upon that by placing a long row of major wind machines just 
far enough away that they don't interfere with turn-table operation. 
If it ain't blowing, just align the berm with the wind machines, 
flick a switch, and hold on to your hat.

But the best improvement is to build a circular rail road around the 
turn table with all the wind machines mounted on a train. This way, 
you can always position the wind machines in line with the prevailing 
wind and augment the natural breeze when needed.

Let me know when you're done... :o)

Happy Holidays!

[RCSE] Wind and molded myths

[Dieter @ ShredAir]

I wish to take issue with statements that a pilot with 18-months of 
flying experience cannot handle a good molded sailplane. I can only 
speak for our line of planes, but they fly more precisely and 
consistently and predictably and with overall much better performance 
than the crates usually recommended to beginners. How can consistent 
and better handling be bad or difficult?

Would you tell a 1-year skier, s/he has to stick yet another season 
with bent-up fence boards taped to the boots instead of a decent set 
of skis and bindings? No? Why then should a pilot with a season and a 
half under his belt continually be frustrated with questionable gear?

When set up to the instructions we provide, an intermediate pilot 
will enjoy flying our molded planes. Of course we will work with the 
pilot and suggest an appropriate set-up and flying style at first, 
and we always recommend flying with more experienced company.

In past events, I have used every opportunity to hand my demo planes 
to intermediate pilots to show them how ridiculously easy and fun 
they are to fly. I will continue to do so, so don't be shy to butt in 
when you see me having to much fun out there.

I'm donning my Nomex suit, and I look forward to the responses.

For the record:
Marcela Leal (who took the pictures), myself,  and ShredAir are in no 
way associated with Northeast Sailplane Products (NSP), mainly 
because we obviously will never attain NSP's level of ethics, 
professionalism, and expertise.

[RCSE] ShredAir Sale

[Dieter @ ShredAir]

This is our first sale since ShredAir started 2 years ago. Sale items 
include F3F and F3J gliders, hotliners and F5F gliders, some EDF 
(electric ducted fan) planes, a few Plettenberg/Schulze systems for 
EDF and helicopters, and a 1/3 scale Lo-100.

Also, due to the consistently high US Dollar exchange rate, we have 
adjusted prices on many of our products. Thanks for the bandwidth.

[RCSE] The annual Eagle Butte pilgrimage

[Dieter @ ShredAir]

This year, we're attending the S&E Modeler scale fun fly at Eagle 
Butte on June 9 and 10, and we're staying to fly at the various 
slopes for a few days thereafter. For those attending the event, the 
following ShredAir slope and F3B planes will be on hand to inspect 
and to test fly before and after the scale event on each day: 
Brisk-II, Scar, Space, Stratos SR, and some electrics, if necessary. 
Some demo planes may be for sale, but we do not intend to bring NIB 
planes unless pre-arranged (please e-mail privately).

Eagle Butte is a world-class slope site which can produce incredible 
lift. The site is privately owned and must be treated as such. 
Dynamic Soaring is not possible at Eagle Butte, but on nearby Kiona 
Butte, which is public land administered by the Bureau of Land 
Management (BLM).

Eagle and Kiona have easy landing approaches and good LZs, which 
makes them different from Chandler Butte, another BLM site nearby. 
Chandler is an awe-inspiring, west and north-west facing bowl. 
Landing there is not difficult for seasoned slope pilots but can be a 
bit intimidating for novices and those used to having large LZ's and 
flying "normal" landing patterns.

If you have any time at all, come and enjoy the hospitality of the 
Mid-Columbia Soarers, the local club. June is typically an excellent 
month for catching the good south-west slope lift at Eagle Butte.

Best,

Dieter Mahlein, ShredAir

Martin,

Assuming the spar is OK, slice open the leading edge where the top 
and bottom halves are joined (this is usually pretty easy to do). 
Being near the root, you will be able to make yourself an airfoil 
template for a foam insert into the D-tube. Size the insert big 
enough to stiffen up the affected area.

You may have to slice open the LE quite a bit in order to insert the 
foam; don't worry it, if it was easy to slice open, it'll be easy to 
glue back together with epoxy; hold closed with masking tape.

Test-fit the foam insert by holding the LE closed and checking for 
fit. Once it fits well, mix epoxy with some filler like Cabasil to 
make it just a little less runny. Pry open the LE and apply the epoxy 
between the foam and the wing skins; apply some to the LE where it is 
split open, and squeeze it together once to wipe off excess epoxy. 
Then, tape the whole shebang shut length-wise with 2"-wide masking 
tape: stick the tape to the bottom or the top of the wing, and 
carefully fold it around while squeezing the LE together firmly.

[RCSE] Soar Utah 2000 picture pages

[Dieter @ ShredAir]

Hello everyone,

As part of our new Event Album pages, Marcela has uploaded a few 
pictures of Soar Utah 2000: http://shredair.com/album.html

No need for us to remind everyone who didn't make it what an 
outstanding event they missed, Paul Naton's video rubs that in 
adequately...

While you're at our site, look at some grainy flying pictures of the 
new Stratos SR-Slope Racer (http://shredair.com/stratosr.html). 
Grainy because winter slope'n on the Oregon Coast does not usually 
come with a lot of sunshine...

Marcela will soon upload pictures of the Southwest Soaring Challenge 
in Phoenix, an excellent contest put on by the Central Arizona 
Soaring League every February. These picture will show lots of 
sunshine and ShredAir hats, pilots posing with planes, planes being 
launched, and planes being "landed." Everything else in between is 
tedious dawdling (TD)...  spoken like a true Homo slopeiens, I better 
go now...  :o)

Actually, the Mew Gull is Eric Swenson's that has also flown as an 
electric-powered model. The little booger was a bit of a handful to 
fly on the slope, but Eric did a great job and got quite a few cheers 
from the audience.

Re: [RCSE] DS, speed- and energy management

[Dieter @ ShredAir]

>Everybody interested in theory of speed- and energy management of
>dynamic soaring have a look at
>www.lfm.mw.tu-muenchen.de/lfm_sources/albatros.html

In a nutshell, this page shows and summarizes the results of 
theoretical calculations designed to optimize the DS flight path. In 
the graphs, the green portions have a positive energy budget, while 
energy is lost in the red portions; the yellow horizontal arrows are 
wind vectors.

The study reports that satellite observations have shown albatross 
flying up to 1000 kilometers by DSing the wind gradient between 
roughly 0 and 20 meters above the water surface.

The pictures of the glider show a DS path on the UPwind side of a 
mountain range but downwind of a smaller ridge. The text does not 
address the significance of the large range is or why it is included 
in the images. It does say that the special head-up display is 
designed to help the pilot attain the optimum flight path, and that 
simulated and real-world experiments are being conducted to determine 
the feasiblity of such aflight path.

Jason,

We can help you at the top-most end. Reinhard Schüler of Modellbau
Schüler has models of exceptional quality that are molded using a
patented method resulting in very hard, dent-resistent surfaces.
Reinhard flies even his 6-meter ASH-26 off  his local slope.
Recently, a friend of mine had a NIB 6-meter Schüler ASH-26 for sale.
Would you like me to check if it's still available? Meanwhile, check

Do try it with a good DS foamie. I have DSd the top of a table top

it worked well. There is enough separation there. I realize your

Re: [RCSE] Higgins Rodent

[Dieter @ ShredAir]

>Anyone know the web site or e-mail address for Higgins planes.  The link &
>e-mail from NorCal slope page does not work. TIA   Bill Grenoble--Shermans
>Dale, PA


Bill et al.,

It's very possible that John Higgins is not taking orders at this 
time. -- Higgins planes are designed for high wind situations and/or 
miniscule to non-existing LZs where even we hard-core slope-heads 
don't want to risk any other plane. They don't fly very well in light 
and even medium lift situations. As you're drooling over the scenes 
in Lift Ticket, keep in mind that they were taken when the lift was 
really pumping.

There are some alternatives to Higgins planes which fly well also in 
medium lift. Check out Brian Laird's excellent line of fast, compact 
slopers:  http://ourworld.compuserve.com/homepages/slope_scale/

And there is the Zipper by the Birdworks: 
http://ourworld.compuserve.com/homepages/slope_scale/. The Zipper is 
also an excellent DS plane.

And speaking of DS, Pat Bowman is now shipping his JW, an EPP wing 
designed specifically for DS; last time I looked over my shoulder, 
the line for one was shortening... :o) 
http://www.bowmanshobbies.com/aircraft.html
The JW really showed its stuff at Cape Blanco at Halloween.

Finally one of the best, fun 60" slopers that will work well 
unballasted even in light lift, is Joe Cormier's Mach-1. Joe doesn't 
have a website, but you can e-mail him at [EMAIL PROTECTED] 
That one's an ARF, about as well done as you can get bagged wings and 
stab and molded fuse, and it costs $300+, and that is a fair price, 
people!

There are probably a few more sources I'm missing here.

If you do want to see some Higgins planes, some of us hard-core 
nutcases will be camping and flying there over New Years.

Best for Y2.001K to all,

Dieter

Hollyday Designs switch harnesses:  I received my first set of 5, and

always looking for. They come with instructions and 
professionally-done wiring diagrams, and Rich Hollyday promptly and

An absolutely excellent wingeron plane is Joe Cormier's Mach-1. The

I have shredded air with it in 40 mph wind.

The Mach-1 is a 60-inch sloper with bagged carbon wings; it's all 
done and painted except for radio installation. You can even buy the 
wingeron servo from Joe and have him install it. I'll gladly e-mail

I'd say that depends on the shape of the fuselage. A slab-sided tall one
will give you more stability than a round and narrow one.
