RE: -?

    The best explanation that I have found for aircraft flight and what
    the controls actually do is the book "Stick and Rudder" by
    Wolfgang Langschlige (sp?). What is covered is straight & level,
    ascent, decent, coordinated turns, etc. I got a copy of this 5-6yrs ago.
    and after I read this, things just clicked and started making sense.
    Of course, there's no substitute for practice, but you don't know what
    you're doing until you know WHY what you're doing is correct.

    The book is fairly readable since the author sticks to practical
    (as opposed to theoretical) aerodynamics. Any good library should have
    this one (or be able to get it) so give it a try.

    For an example of the kind of stuff thats in it consider the following.
    Suppose that you're making a landing approach (engine idleing). If you
    see that you're too high (going to overshoot). Use UP elevator trim to
    steepen your approach. Why? The up elevator increases the angle of
    attack, which increases drag. The increase in drag is what brings you
    down faster. True, when you initially dial in the up elevator, the plane
    pitches up but that is a transient which goes away after you bleed off
    a little speed. If you don't believe it then make a paper airplane &
    carefully watch the steepness of the glide as you vary the trim.
    By golly it works!

I just received my copy of the "Guide to 341 Aircraft Museums and
217 City Displayed Aircraft WWII Landmarks 31 Restaurants with Aircraft"
5th edition.

Some title.

It is 38 pages long plus 28 pages of cross reference.

It is not a high quality publisher type of book but seems
to be a good lead on scale type Aircraft.

Price is $7.00 for  1 to  4 books.
         $6.75 for  5 to  9 books.
         $6.50 for 10 to 14 books.
         $6.25 for 15 to 19 books.
         $5.00 for 20 to 25 books.
         etc.           .25 for each 5 more

         All these include postage (postage free)

Well that is quoting the letter from the author.  I'm sure that
the $5.00 was a typo and I'm also sure that if we purchase
had a large purchase that he would not discount 25 cents for every
5 copies.  At 140 copies they would be free!

Anyway the author/address is
      Michael A. Blaugher
      124 East Foster Parkway
      Fort Wayne, IN 46806-1730
      1-219-744-1020

I brought my copy in to work and will keep it here for some time
so if anybody wants me to look up their favorite aircraft I
will make myself available for phone calls - DTN 226-6306

P.S.  The author says he has 18 more museums that he is working on.

This is a collection of little short stories about full scale flying.
I have only just started it and find it quite enjoyable so far.

Each little "Rambling" item varies from 1/2 page to 3 pages long.
Nice and bite size.  It is a large hard bound book of professional
quality.  $18.50 + $3.00 Postage and handling.

Available from 
	Arizona Soaring Association
	P.O. Box 41384
	Phoenix, AZ 85080-1384

If you like soaring and you like Rambling then you will probably
like this book.  Warning - as stated before - I have only just
started reading mine so this is a very questionable review.

================================================================================

    Kay,
     
     William Green is a British author who has written a series of aviation
    books over the years, I have no idea how many but it's a lot, and
    is generally considered to be the leading authority on WWII era
    aircraft especially in terms of searching out and documenting their
    specifications. 
     I have 5 of his books, 4 vols. of "All the Worlds Fighters", each
    vol. covering a group of countries and their aircraft from the 1935-45
    era approx. He has also published "All the Worlds Bombers", jet
    fighters , helicopters , etc. etc. You name and Green probably has
    written about it.
     I also have "War Planes of the Third Reich" THE definitive work
    on 1930-1945 German combat aircraft that actually saw the light
    of day i.e. no drawing board only stuff. His research is exhaustive
    with full specs. on all models and derivitives of a given type,
    and a lot of interesting old photos, and 3 views of course.
     I've had my books for about 16 years "W.P.T.R." has gone thru several
    editions and is still in print I think. Not sure about the others
     Zenith Aviation books in Wisc. has carried them , they advertize
    in "Wings" and "Airpower" magazines, I got all of mine in local
    book stores. Hope this helps.

Due to some requests for information I thought I'd post a reference list 
I've compiled for aerodynamic data for airfoils at low reynolds numbers
(low speed) and some for sheared-tip aerodynamics as that has been a 
topic of discussion here and in sci.aeronautics.
 
----------
 
The following is a list of some useful references for those who are 
interested the aerodynamic data of low reynolds number airfoils.
 
The list is by no means exhaustive but it represents a good cross-section 
of the available data.  If you need still further information, the 
references listed in the below works will lead you where you will want to 
go.

    I'm looking for a basic book on aerodynamics. This book would describe
    things like laminar/turbulent flow, lift/drag, reynolds numbers, etc.
    This would ideally be a book that describes such things in terms of
    kites, but kite research pretty much stopped when airplanes were
    invented.
    
    Thanks.
    
    		Marty Sasaki
    
    p.s. Many kite flyers/makers prefer to think that airplanes are just
    kites without flying lines.

	Re: .250   

	The best book on flight and aerodynamics I have seen is
	"Mechanics of Flight" by A C Kermode  (ISBN 0 273 31623 0)

	It is(was) the standard text for all aeronautical engineering
	courses in the UK  (I used it at college).

	Don't be put off by the high technical content, it's very
	readable and takes you from basic concepts of mass and inertia
	through all aspects of flight to supersonic flight. 

	Highly recommended.

From CASA COMMENTS - The newsletter of the Capital Area Soaring
Association, December, 1993, Gus Peleuses - Editor.

CASA LIBRARY - George Frechette

Books

"How to Build and Fly Radio Controlled Gliders", by Jack E. Schroder, 32
pgs., 1980. Good small book - covers the basics.

"Radio Controlled Gliding", by Dave Jones, 192 pgs., 1987. Best of the lot
- covers all the basics and many practical considerations - including a
discussion and recommendations for foul weather gear. A British author and
admitted thermal soaring fanatic. The book is indexed, contains several
useful appendices, a glossary, and the author has a good sens of humor. It
also includes slope soaring material written by a guest author, Keith
Thomas, an admitted slope soaring enthusiast.

"Flying Scale Gliders", by Charles Gardiner, 63 pgs., 1989. The key word
in the title is "Scale" and the book is devoted to scale. Also a British
author, with slope soaring as the primary flying technique, and a lot of
lobbying for formalizing and standardizing this aspect of the hobby.

"Basics of Radio Controlled Sailplanes", by Alan Gornick, Jr., 76 pgs.,
1989. It also covers the basics, has good explanations, and is well
written. It is strong on model recommendations both from the building and
flying aspects. The author leans towards slope soaring and includes a
chapter on aerobatics.

"Sailplane and Soaring Manual", bu AL Doig, 141 pgs., 1981. Covers all the
basics and is a must if you are scratch building with about half of the
book devoted to construction instructions for an Olympic 650.

"Radio Control Thermal Soaring", by George Stringwell, 383 pgs., 1988.
This book takes time to read. Also a British author and loaded with
pictures, diagrams, appendices, and building ideas, but he forgot to
include an index. It may be too intimidating for someone new to the hobby.

"Old Buzzard's Soaring Book", by Dave Thornburg. It is thirteen essays
which are expanded and updated from their original appearance in MODEL
BUILDER. It is good reading. It is light reading. It is informative. A fun
book.

"Model sailplanes without Myth or Magic", by Tony Upso, 200 pgs., 1993.
Really different - a book without pictures, yet readable and enjoyable. I
learned enough to want to re-read the book and take notes this time
around. Two most pleasurable themes - debunks airfoil selection as a
meaningful factor and describes why high tech stuff is a waste.

>>> around. Two most pleasurable themes - debunks airfoil selection as a

    Now THERE'S a couple of themes that should spark some discussion.
    

    Considering the fact that I havn't seen or read about any Gentle
    Ladies in the winners circle lately, can someone expound on why
    airfoil select is NOT meaningful and high tech stuff is a waste??????

    Could it be that the winners are not flying this glider.  I suspect
    that the eperts can win with almost any glider they fly because they
    are so use to flying thier ship over long periods of time (re: Fisher
    and Rieth around this area). I also suspect that the chanps use
    different airfoils depending on the contest conditions.
    
    For example, the Spirit 100 won the Nats in 1990 (?) but no one else
    seens to be able to really win with it since.
    
    Ollie

    B. S.    There's more to it than that.  The good pilots have good
    planes that are set up to fly well!  Give a dog to a good pilot and
    he'll tell you what's wrong with it and give it back.
    
    Charlie
    

    RE the Spirit 100 winning the 90 nats. True, but don't forget the
    Spirit 100 has a "high tech" airfoil. 3021 I believe.
    
    Anyway, it depends on how you view "high tech". Charlie is right in
    that the key to winning is KNOWING your plane and having it set up
    right. Most of the "experts" can make anyone look silly using a flat
    bottom floater.
    
    If you look at "high tech" as an AID to flying and NOT a substitute
    for experience and knowledge then I think there is a definate
    advantage. If you think "high tech" will make you a better flier
    just because it's "high tech" then your in for a big surprise.

    I didn't see anything specifically related to scratch designing &
    building (glow) powered models; any suggestions?

    Love to see you fly a "Dog" Charlie! :-) Maybe you can get one that is
    tail heavy! :-)
    
    E.   

    Better yet, fly a Dachusen (SP?). You need that LONG TAIL moment for
    stability. There not good on rough fields though. Landing gears too
    short.

    I've seen pictures of flying doghouses but no flying dogs.
    

    AIRDALES usually fly pretty well. CG is critical though.
    
    Also, beware of neutered dogs. They tend to be NOSE HEAVY.

    Dachund.

      I'm trying to locate a book on WWII Russian aircraft. Just got the new
    Zenith catalog, and so far haven't located anything specific to that 
    country and timeframe.
    
      I remember that one of the recent (last two months or so) model rags
    had a short blip on a book just on this topic. Now I can't seem to
    remember or locate it, figures right. Anybody remember this article or
    know of where I could possibly locate a book specifically on this type
    of aircraft? Looking for info on the YAK's, Mig's, IL's, and LA's.

Ask Al Casey (Mr. Russian model aircraft).
He is available at (602)993-0122 in Phoenix.

Tell him Kay Fisher sent you.

He just called me yesterday by the way - the next Phoenix Scale Fly-In
is March 12th and 13th.  The next weekend (the 18th-20th) is a full
scale unlimited air races at a recently closed down Air Force base
south of Phoenix - course you could elect to stay here in the cold!
I booked my airlines tickets last night!

Model Sailplanes without Myth and Magic

by Tony Upso

I'll quote from the cover

This compact little book is an insider's guide to the 
mechanics of sailplanes.  Professionally written for the
layman, beginner to expert, it may also be enjoyed by
wives, lovers, and other interested bystanders.  The hows
and whys of model sailplanes are carefully explained in
simple term that everybody can understand.  This is not a
"how to..." cookbook, but rather presents the basic theory
and design considerations of concern to all sailplane
enthusiasts.  Reality is separated from the host of quasi-
technical fables so prevalent within the hobby.

Pertinent and sometimes impertinent topics include:

     	- How does it fly?
        - Do you know how to launch?
        - Is your tech high enough?
        - Is your airfoil sophisticated?
        - Are you sure you want to ballast?
        - What about this boundary layer business?
        - What does the horizontal tail do?
        - The trailing edge need not dice carrots!
        - Is your glider any good?
        - Design your own but be careful!
        - It it "sink" or something else?

Tony Upso, a professional aerodynamicist, is one of the
recognized authorities on reduced-scale simulation and has
worked at the forefront of aeronautical technology for
some 30 years.  He is also a designer, builder, and flyer of
radio controlled sailplanes.

===============================================================================

Well - I got it for Christmas and just finished reading it.
I found most of his conclusions questionable and out of the
mainstream.  I didn't particularly enjoy his writing style
to the point that I skimmed most of the second half of the
book.  I subscribe to many RC magazines and have read many books
about gliders both full scale and models.  Given this on a scale
of 1 to 10 I would rate this book at 1.

But - maybe I'm all wet.
Maybe my ignorance is showing and this is a great book.
Maybe if you want to borrow it you should send me mail.

I will gladly loan it to the first person who agrees to
also write a brief review for this note.

If interested see me or send mail to GAAS::Fisher for
your chance to criticize my critical review.

    As many of you may remember, I have been looking for a number of WWI
    aviation books for some time now...  
    
    Well, this search has led me to what may be one of the biggest

    He had 2 of the 4 books, and he was surprised that he was out of the
    other two...  He claims to have some 4 airplane hangers worth of
    out of print books and old magazines that cover Air/sea/land topics.
    He has numerous full sets of Profiles, Cross & Cockade, and original
    model magazines dating back to the 20's!
    
    He also has a 10,000 volume research library, with lots of drawings, 
    spec sheets, and pictures.
    
    He claims that the Smithsonian and numerous museums refer people to
    him.   He is a friendly sounding guy, very willing to help.  This
    could be a huge resource to scale modelers.
    
    BTW - I asked where he advertised (I was refered to him by another 
    book co.) and it is very limited.  He does not advertise in the 
    model aviation pubs because they are too expensive!
    
    He makes all shipments UPS, signature required.  His prices seem to be
    in line with other collectors that I have seen, and include shipment.
    
    Sorry to say, but he does not generate an inventory list/catalog.
    
    Tell him that I sent you....  (No, I do not get any benefit from this,
    except perhaps he will work a little harder to find the 2 books I 
    still want...)
        
    cheers
