ACCURATE REPORTING, ANOTHER ANGLE
In addition to the well-publicized need for ac-
curate Facts, there are other needs to be met
if the reading public (in this case, you, the
membership) is to get at least an approximately
true picture. Eg: a recent book (title and sub-
ject for the moment to be withheld) received
rave reviews in all the avmagazines and avjour-
na 1s. We wanted it revi ewed by experts who
really knew the subject, and discovered to our
surprise that the experts we asked thought it
so bad and error-full it was impossible to re-
view- so no review has yet appeared in WWI AERO.
A problem to which Jim Sanders (SMALL AIR FOR-
CES OBSERVER) has addressed this letter:
What a shame that there is controversy over
XXX. It is a magnificent photo collection
many of which are of aircraft completely un-
known to the general enthusiast ... The mistakes
and
omissio~
can, and should be, corrected by
those wi h more knowledge than either you or
I. And, if credit has not been properly given,
then this too should be brought out into the
open. It is too bad YYY will not do a review.
Such a review would be a great service to the
reading public, and if the lack of proper ac-
knowledgements was inadvertent, such a review
would be also vlelcome by the authors. If not
inadvertent, their silence will condemn them.
In the absence of a review by respected autho-
rities in the field, I believe that it not im-
proper for us to review the book as to its
worth to the average reader, while including
any caveats of which we may be aware. If YYY
writes to me, I'll be glad to include his com-
ments in the next SAFO.
(Ed note: since this was written, YYY did.)

In the first paragraph of Bob Cavanagh's
article in #124:35, the sentence beginning
"Flying Cadet Charles A Lindbergh ... " should
have read: "Flying Cadet Charles A Lindbergh
was flying SE5E AS No 22-310 with Wright en-
gine AS No 49466 in the #2 position and 2d Lt
Charles D McAllister, another student pilot,
was flying in the #3 position in SE5E AS No
22-300." Reference to McAllister and Lind-
bergh's
alc
were inadvertently omitted to-
gether, putting Charies in the wrong
a/c.
Sorry, Bob! (Bob speculates on the number of
errors now in historical records due to typos
and inadvertent omissions: your Editor feels
that while these certainly exist, the damage
done historically is much heavier from other
causes- like those referred to in recent Histo-
riography essays in WWI AERO.)

WE WILL MISS:
Robert GEoff died on 20 Jan 89 at his
home in Laguna Beach, CA, at 93. He was
one of the last
survivors
of the Lafa-
yette Escadrille. (Jim Parks reports the
only two current
survivors
are
Hen~y
Forster, 100, on NYC, and Reginald Sin-
claire, 96, of Colorado Springs.)
Ernest Rodgers died early this year in
Panmure, New Zealand, at 91. He flew
Camels on the Somme till a test-flight
crash damaged his sight. He described
the Camel as "a sturdy 1ittle pl ane that
made a noise like a sackful of empty
tins" because of the aluminum pistons
(?-
Ed).

We
have
had a good many 1etters about a UK
plans seller, Jim Dudgeon (Eggerness Farm
Cottage in Wigtownshire, Scotland): there
seems to
have
a lot of problem about orders
not filled and letters not answered,
even
when money was sent. Our recommendation:
don't do further business here.

Our review of Bill Hannan's PEANUTS &
PISTACHIOS Vol IV in #124:108 reported
it as having 56pp and costing $9.95;
instead it should be l6pp at $7 incl
postage and handling. Wonder what book
we were looking at! But P&P IV is worth
$9.95, even
at 16 pp ...
A CHANGE:
Ron Moulton retired on 15 May 1989 as pub-
lisher at Argus Specialty Publications of
several excellent British model magazines,
notably AEROMODELLER, and the other MAP
publications. In 39 years Ron developed
these into the flagship model magazines of
the world. His home address now: 2 Avenue
Rise, Bushey, Watford, Herts WD2 3AS, UK.
Ron assures his friends that he is not
bound for hibernation ...

AIRCRAFT
De Havilland 4B - 70% Scale Reproduction
Roy 0 McCaldin, 410 S Brighton Ln,
Tucson, AZ 85711
Earlier I showed photos of the complete but un-
covered
airplane sitting in the back yard (WWI
AERO #122). It was licensed in March.
According to Boyne's monograph (DE HAVILLAND
DH 4. Vol. 7 Famous Aircraft of the NASM.
Smithsonian Institution Press, Washington, D.C.
1984.) the U.S. purchased the British design,
started production in July 1917, and finished
the first aircraft four months later. By 1919
there were 4,846 of these aircraft built. This
reproduction took a little
over
five years to
build. I don't think I'll try to build more of
them.
Flight characteristics of the original DH 4 can
be summed up by one of its early test pilots,
Maj. Gen. Wade, USAF (Ret.). He said it was
" ... an ordinary airplane that flew exactly as
he expected it to, with no unreasonable virtues,
nor unconscionable
vices."
This 70% scale rep-
lica can almost be described that same way. In
order to meet the balance requirements, the nose
was extended 7". This enlarged the side pro-
file which in turn makes the ship sluggish with
respect to yaw - a problem readily solved by
paying attention to the needle-ball and rudder.
It was a challenge to make this replica as true
to the original as possible. In addition to
the nose extension, the body width could not be
fully scaled down. The minimum finished width
(enough to accommodate the crew) was 25" as op-
posed to a scale-width of 21". The seat ar-
rangement is that of the DH 4B model. The B
was just the first of many changes incorporated
in DHs during the 1920's. Another modification
in 1921 was to install new landing struts and
move
the wheel s 7," forward. I found it neces-
sary to do the same (al though only 3") in order
to maintain some tail weight on the empty air-
plane.
Tes t work is presentl y under way. However,
early flight results look like this:
Take off roll
Climb
Climb rate (mid-weight)
Cruise
Top speed
Stall, power off
Stall, power on
Landing touchdown
300'
60 mph
600 fpm
75 mph
85 mph
45 mph
c 42 mph
c 40 mph
The disparity between stall speed and landing
touchdown speed is interesting. It feels as
though there is an appreciable ground effect at
