Hi Bo,
Interesting thread! Telemaster radio.

An important question to answer is, was it a straight antenea as you show in your example or a CLC antenna?
Maybe the catalogue can answer this question or..... you already did check this yourself.
Fact, when the original was a CLC, is a Center Loaded Coil, then you need again such an antenna or, you have to make one because tuning of the output is only possibe with the right dimensioned and type antenna.

For tuning you need a simple instrument as a fieldstrength meter wich you can make yourself if you want.
When it isn't known about the type of antenna you also can use cupper wire and a fieldstrength meter to find out and do some research of the transmitter in the first place.

Jag ser gyre på bilden. Vet du Telepilot gyro rodermekanism?
Gyrot var ett sinnrikt sätt att manövrera ett roder eller rättare sagt sidoroder. Denna rodermekanism bestod av en elmotor arbetande på 3 volt spänning med en liten mekanism som bestod av en slunga som kastade ut vikter, ju högre hastighet ju längre ut kastades dessa vikter ut. I s(l)utändan gav då motor full fart roder åt ett håll och ej aktiv motor roder år andra hållet, detta andra hållet åstadkoms genom att ett gummiband eller en liten dragfjäder utgjorde kraften.
Flygning rakt fram sker genom att gyrot pulsa’s ut att stå och pendla i mittläge.
Min fråga är, har din sändare en generatorn för sändarpulsen för mittläge?

General about GYRON mounting and usage
GYRON must be mounted with a slight side angle to prevent  bending
tendency that occur via pull linkage to the rudder horn. The horns that
is shipped with the unit should be mounted so that a standing still
GYRON gives left rudder.
For the pull linkage use piano wire 1,25 mm. The suppled brass rings are
mounted on the linkrod and soldered there so as the rubber tube linkage is
achieved at the GYRON and at the rudderhorn (30-50 mm from rudder horn
and outside the fuselage). Om boats it is enough with one such rubber
tube linkage. For the pull linkage attachment to the rudder horn a
safetyconnection must be in use. Use a rubberband for a pull force
on the left side of the rudder horn. Rubber band should be as long as
possible and it must be easy to adjust the tension. Approximately right
tension is when right and left deflection is with same speed of motion.
Let and right deflections should be blocked to the suitable deflection
angles for each model. A piano wire (0.75 mm) that is soldered on each
rudderhorn and pointed forward against the fin where the wire is bent
to give suitable deflection angle is an easy solution on the rudder
limit deflections.

Important 
For a GYRON to work good it is neccessary with soft
mounting, GYRON must be placed on a soft foam rubber material (10-20 mm
thick). Both the soft foam rubber and the GYRON must be bonded with
PLIBOND - a new revolotionary glue - that guarentee a firm but at the
same time soft attachment of both Standard-GYRON and Super-GYRON. (One
tube PLIBOND cost 1:75 SEK).
Apply glue 2 times both on the soft foam rubber and GYRON with PLIBOND
before assembly is made (follow instructions for the glue).
A glue string of 8 mm width applied under the external tube on GYRON
is enough for enough strength.
On boats a balanced rudder must always be used. Maximum rudder
deflection on a boat is approx 22 degrees. If not enough stearing is
achieved with that the rudder area must be increased.

Flying instructions
Use small defelections to start with!
Check that left deflection is not exeeding 2-4 degrees. Too large
deflections on first flight (before more experience is achieved) will
easy result in a crash. Therefore make the first flight with the left
rudder deflection very small and then You will be successful from the
start.
After a while the deflection can be increased for steeper turns but
still with secure starts. Adjustment is made on the rubber tube outside
the fuselage. After some practice You will find how easy and secure You
will fly with a GYRON in the model.

Some advice with pulsing for proportional control with GYRON:
Check how deep the transmitting button must be pushed to give good
contact. It is easier to get the right pulse rythm if the thumb motion
is minimum. Check the rudder from behind when pulsing with the button
and exercise a rythm of equal signals and pauses. Pulse rythm does not
need to be fast! The rudder (with the rubber band properly adjusted)
should have a similar swinging motion around neutral position.
If signal lenght is inreased or decreased the rudder will be more to the
right or to the left. After practice and with a pulse of about 1-2
pulses per second a very good proportional stearing can be achieved.
Use of a pulsebox outside the transmitter is not needed.
To get most out of a Super-GYRON as rudder mechanism it is important
that following is used at mounting and pulsating:
Pull linkage rod is placed in inner hole at rudder horn (so short
moment arm is achieved). That way a faster deflection is achieved by
shorter movement of the arm in the GYRON. Pulsation of Super-GYRON must
be made in very slow pace. For maximum deflection to the RIGHT a long
signal must NOT be used but instead long signals with short pauses.
For maximum LEFT deflection the signal must not cease completely but
instead the GYRON motor should be held in slow rotation but without
rudder deflection is achieved.

Hi,

A little update on the antenna for my Telepilot 1 ch radio.
I was able to find a brand new antenna for it, it is a two piece antenna, 125 cm / 49.2 inch long.
Not bad.
I have new tubes on order (rested) but should arrive later in December from the supplier.

I got a almost new Telepilot "Digiplex 3" (3 ch) proportinal made about 1971 some time ago.
I will try to find an antenna for that radio also - missing of course...
It is a real nice radio that You hold in one hand and have the throttle on the top of the case.
It is a 27 MHz radio and it should be nice object for adding a 2.4 GHz module and start to use it again.
For servos it was used back in the days Multiplex mini servos with rotary servo arm or EK Logictrol
Mini Mite linier servos. The missing original Digiplex 3 ch receiver will be very difficult to find but
it is not that important right now.
As a side note about the 3 ch Digiplex radio: I remember when I sat at age 11-12 or so at the libabry
and read the hobby magazine "Allt om hobby" (All about hobby), it was issue nr 4 1971 I found out later (and I have that issue now),
and dearmed about a Digiplex 3 radio. It was rather exensive (all Digiplex was - probably whey the production ended in 1973
when Futaba and other makes came with their cheap radios) back then. In 1971 Digiplex 3 with 3 servos (and charger plus 225 mAh NiCd)
had a pricetag of 1145 SEK excluding VAT and that is about US $172. Well 40 years later I have this radio so... better late then never.
 
Does not work to upload images now but I will upload some when it works gain.
Worked to upload images today so here they come.

/Bo
