ATTENTION "OLD TIMERS" (you know who you are.)

I was talking with a long time flying buddy (28 years) about the first
equipment we used and it sure brought memories.

Although there was better equipment on the market when I started I was young
and newly married(no money)

An older fellow was quitting and gave me all his stuff. (Dan Hudspeth) It
included Reed sets, Escapements, and even several Halco "Galloping ghost"
setups.

Any body out there remember using this stuff??

Ah, well, I remember reading about it fondly back then,
but couldn't afford any of it at the time . . .

Newer modelers probably wouldn't believe what could be
done with a rudder-only escapement plane if you told 'em.

Lovingly crafted Hal DeBolt 1/2A Champ, some sort of OK Cub glow engine,
Controlaire 5 superregen receiver, Mule transmitter, single function
escapement (brand?).

I worked hard all summer 1965 to earn enough 'extra' money to buy all that.
Two glorious flights followed by a re-kitting. Expensive first outing, but
enough to get me hooked for life!

I remember these types of equipment as fondly as my altair...
Propo was of age when I started but, I did have some reed flights
to see what it was all about... Now, was that 4 clicks for up or 2?
took alot of planning then, just to takeoff.

Yes, but not very fondly.

I had a Galloping Ghost setup around 1967-68. It was
fascinating to watch it work on my bench. Never had any
success with it in the air.

I was too young and too proud to ask for enough help to
make it work. I just kept patching up the planes and
trying again. The longest flight was perhaps 45 seconds.

More my fault than the gear's fault, actually.

REMEMBER IT ??? I still have some of it...

How about a Controlaire Single Channel Tx... w/a Bonner stick on it
(Galloping Ghost), Companion Rx and dual rand actuators with a rate
decoder for elevator?

At one time , a "State of the Art " system....

I just finished a Tri-Squire with Galloping Ghost. I am using a home made
transmitter that I built in 1964 with a Controlaire SH100 receiver. The
actuator is also Controlaire. I used the single crank on the tail so that
non-believers could see only one connection to the rudder and elevator.

The purpose of this is to show the younger generation that it did work!

Got into the hobby when 10 channel reeds with the capability of simultaneous
controls (two simul. inputs) was just coming to market. Remenber seeing my the
Astro-Hog for the first time in late '59 equipped with the HUGE K&B .45. Man
that was the ulitmate! At least three real active fliers in our club (Delaware
RC) successfully used the Good TTPW system (as kitted by Ace). Still have my
Min-X 1200 GG system. Flew the heck out of that sucker. Still have about 7 or
8 various superregen Rx's and escapements and Mighty Midget motors. The funny
part about all of this is that I saw all of this stuff flown very successfully
in the early 60's. I think those that flew in the mid to early 50's are the
ones who really deserve credit. Tone RX's seemed to be much more reliable than
the earlier Carrier Wave types. And they came into vogue in the late 50's,
early 60's. At least they did where I lived.

I started in this hobby in 1954. In '56, I built my 1st radio...gas tube, hand wound
coil and a relay the size of a quarter(THAT was some impressive relay). The
'B' battery in the A/C weighed as much as some of my planes do now!

Graduated to an ACE single channel in 61/or 62. It was a kit and still a tube radio.
Basically the same as the 1st one but it was a superhet...way sophisticated
technology. Still drove the rudder with a rubber band escapement.

In '65 I bought an OS single channel with two motor driven escapements. One for
rudder and 1 for throttle(3 positions on throttle). This was a great little outfit.
4 AA batteries in the plane and a nine volt battery in the TX. Had it in a Jetco
Navigator. Flew it for at least 5 yrs at the cottage.

In '66 or 67 we REALLY moved up...analogue proportional! I forget who made it
but it was in a beautiful red aluminum case. Had to have one it looked so nice.
Well, the servos moved so slow that you could easily crash yr plane before you
got control of it. What a waste of money that was.

Just about this time Heathkit came out with a digital propo which I built and flew
for several yrs. Oh yes, there was a KRAFT propo in there somewhere as well.

I wonder how many of you remember some of these old attempts at RC?

Back in about 1956 , I took my first radio (Berkley D-E Aerotrol) in
a Mambo with a OK Cub .099 (VERY underpowered), many times over on
week ends to try and get the thing to work.. Plane flew fine, radio
just kept keying escapement constantly. Worked fine at home, but not
at field. Was not untill years later that I found out that a Raincoat
Factory next to the field used RF to heat
seal the coats togather. ON 27 Mhz Yet.

Good Old Days????

Gord, the analog propo in the red case was made by Citizenship, I bought one
and recall well how s--l--o--w the two propo servos were. (On the other hand,
they didn't have much thrust/torque, either.) Do you remember that the
throttle channel wasn't propo, but instead was a "run while the lever is held"
positionable type?

I was in the Air Force at Grand Forks AFB, ND at the time ('66) and sold the
system to another Air Force type when I was transferred in '67--I'd never
actually flown it. This guy was an absolute electronics whiz (and is now a
computer profesisonal and even more of a whiz in that field), and he actually
used the Citizenship analog system as the foundation for his own-design
_digital_ propo system!!

Orbit also had a three-channel analog system in the '66-'68 era.

FWLIW, my RC beginning was in '65: my first ship was Bill Winter's "Swampbox"
(MAN, Dec 64...and the plan is still available from MAN!!), powered by an O.S.
Max .10 RC, and controlled by a Min-X Pulsemite 1200 galloping ghost rig (which
i still have). I flew it first in only rudder/motor mode, and derned if it
wouldn't do a half-decent touch and go...though the timing of advancing the
throttle to pull the nose up was a challenge.

Later, I replaced the Ted Strader Du-Ac actuator with a just-released Rand LR-3
actuator, and pretty decent proportional elevator and rudder (with
five-position throttle) was a reality. The Swampbox made some very pretty,
flared landings...and since up elevator was the lowest pulse frequency, it was
a hoot to see the ship's nose "bobbing" just before touchdown.

I will always remember my very first RC flight in May 65. Squadron-mate (and
experienced RC flier) Will Greenwood hand-launched the Swambox for me and
coached me through the flight...which was a solo from the first instant. (I'd
been a FF modeler since the early 50s, so building the Swampbox "square and
straight" was not a challenge...and typical of Bill Winter's trainer designs,
"hands off" would let the ship recover from almost any pilot error.) The
highlight of that first flight was that I landed the Swampbox on its wheels (a
taildragger design), and on the runway! Onliest "Yeah-bu!" is that the landing
was _across_ the runway, not down it. (I just declared victory and pressed on
from there. <g>)

Hey guys, these stories are great!  I came along in '68 at age 12 with my brand new Heathkit GD19A system.  Saved up money from my paper route (219.95!) to buy it.  The guy up the street gave me a framed up deBolt Champion.  My grandma gave me an Enya .19 for x-mas.  Whatta blast!  My dad and I went out to try and fly it.  First flight was a climbing right turn into a right turn into a right spiral into the ground.  Nose broke off.  Fixed it and after many trials and tries, finally got it all figured out.  Still have the ol' Heathkit downstairs.  Thanks guys!

Curt -- I started my first R/C model in 1954. It was a new design put out by
Dmeco called the "Live Wire Cruiser". It was powered by a K&B Greenhead .23.
Hal DeBolt had a "servo" he designed and I used that instead of an escapement.
It worked about 50% of the time (no kidding) but I flew it anyway. Actually it
flew better as a free-flight! It had a Babcock single channel radio which
required 3 batteries, 1.5 volt filament battery, 67.5 volt "B" battery and a 15
volt bias battery. I had a lot of fly-aways but I always got it back! Aah, the
good old days!!!

This is a thread to which I can relate. I started with single channel
a British rudder only unit (Reptone?) with a block Rx and motorised
actuator - didn't work in the Canadian winter. But the Tx was OK with
a Kraft single channel (tube) Rx from ACE, and with the later K3VK
transistorized version. I had a Wildfire bipe with Babcock compound
escapement and a clockwork Fred Rising escapement on motor. Then went
to Reeds with Kraft 10 and 12 channel units with Bonner Duramite and
Transmite servos and Annco servos. Pretty good stuff provided you
kept the Tx channels accurately tuned to the reeds, and served me well
in a FROG Jackdaw, a Palmer G-String and of course the Taurus. I
avoided analog proportional but had the first PCS (Kraft) unit.

Still have a couple of ACE single channel rudder only models which are
most enjoyable to fly.

An escapement is a rubber driven device used to give left and right rudder. Basically,
it is a relay with an L shaped armature on it with the pivot at the right angle.
The arms of the L were 'stoppers' for the ends of a rotating arm that was driven
by a long rubber band to the rear of the A/C. There was also a means to hook this
driven arm- mechanically- to the rudder. With no out put from the Rx, the rudder
was at neutral. Key 1 time and hold at the TX ,and the relay pulled in releasing one
end of the rotating arm allowing it to turn 1/4 turn giving right rudder. Let the TX
key go and it went back to neutral. Key 2X and hold, and the opposite end of the
rotating arm was stopped by the armature giving left rudder. Turns were done
by giving succesive 'bursts' of one or the other although one had to be careful not
to run out of power on the elastic. Of course, all the planes were free flight
anyway and trimmed to always turn slightly, so not too many planes were lost.
A little after this wonderful gadget was invented along came a method to couple
a second escapement to the 1st so that a quick jab on the TX button would cause
the 2nd one to rotate. This could be hooked up to the throttle. Man were we
sophisticated then! Way cool!

Escapement, a clockwork mechanizm that advances each time a radio signal
triggers a relay which pulls in a coil on the device allowing it to rotate
a shaft 90 degrees or so. When the radio signal releases the relay it goes
back to where it started. Now how did we control a model with this.....One
hold = right, one on,off,hold = left. Then we got sophisticated and ganged
these together so that a very quick blip of the radio set off a second
escapement for throttle, usually high or low speed. We flew rather large
planes with small engines. A tpical set up might be a 56 inch span with a
.15 size engine.

Escapement - It was your best friend or your worst nightmare. I started
with a Babcock 27 unit a C/G Skylane 42 with a Cox Mediallian .049. Had
a 2oz metal tank in the nose and the dang thing would fly around 10
minutes. If you didn't watch yourself you could run the rubber down and
the chase the plane several miles. But hey, I was a kid, right! Later
I lost a C/G Jr. Falcon because of the same problem of letting the
rubber run down.


Ok an Escapement was notheing more than the inerds of a windup alarm
clock only converted over to R/C use. Gee, I really don't know how to
discribe these just that I had more fun playing with them than anyone
should have.

Yes, I remember that stuff, as a youth who hung around the flying field in
Springfield, Illinois, in the mid 60's I bought some escapement equipment
from older modelers who had moved up to better stuff. Had a humongous
Heathkit transmitter and receiver, and a Mule Mark 2 transmitter and
receiver. Both gave me uniformly unreliable service, as every other flight
was a fly-away, and in those days when the equipment didn't work it
neutralized and just flew off for miles, the single channel birds were just
big free flights anyway. I saved up my lunch money and managed to buy two
Royal Servos, brushed brass annodized cases, and each probably 2x4 inches in
size, huge and heavy. Back then just one flight when nothing went wrong
seemed like a big accomplishment. The galloping ghost stuff also looked
ridiculous in flight, with the control surfaces flipping back and forth, and
the escapement stuff depended on cool nerves and a good button pushing
ability,because if you didn't time it properly you get two rights instead of
a left, which was the button pushed twice at the proper speed, and when
something was going wrong you could never seem to get left when you needed
it. Modelers now have no idea of how lucky they are to get good equipment at
a decent price.

Yea and trying to get that throttle to change sometimes resulted in no
turns left on the rudder escapement and the plane flying on its own with
full throttle.

That is when I learned to cross country run. :-)
