RE: what was your first radio system?
An ACE kit from ACE at Higginsville, Mo. A tube and transistor receiver, AM 27 MHz. Transmitter was a 1 foot cube sitting on the ground with about a 11 foot long antenna bolted to it's side. A push button to key the transmitter on the end of about a 6 foot cord. Rudder only with the escapement rubber band powered.

RE: what was your first radio system?
My first setup was an ACE but it really did not work and I simply did not have any desire to screw around with it
Next radio was a Digit Migit 3 from World engines with three horrible servos
But -the rf was pretty darn good on 27- I built my nerxt radio from one of their Blue Max 5 channel kits -servos and all - and it was a good radio.
I swapped it to a friend for a new Futaba /MRC which would NOT reject interferrence -he was right - it was no good
Lucky me I mailed it insured - and the post office lost it and I got ALL my money back!!!

Kraft...and I think it was a five channel. $450 bucks ish if I remember correctly and I cut many, many neighborhood lawns to come up with that dough! Put it in a Falcon 56 that I flew off the snow after school more than any other surface. I still have the homemadewooden skis.Then I put it in a Super Kaos that was HOT....but the chicks were hotter. Funny that Ihave more memories of my planes than the girls....but I digress.

RE: what was your first radio system?
That's the NEW stuff.
My first "Bramco".
Look it up................ Tubes, tubes and more tubes
Not to mention relays, one for each channel.
You haven't met frustration untilyou've adjusted relays, not to mention reed banks .
Ground based 5 Watt Tx
Yep FIVE watts and range was a problem !
Of course so was everything else at the time.

I have shown my first radios in a previous posting.
It would be nice to see some pictures of your rig if available.

I had only two double triode in my first radio. It was home brew (made at home).

I needed two relays for each channel ... one for one direction and another for the other direction like one for up elevator and one for down elevator (same for rudder, ailerons and throttle).
Agreed for relay problems due to intermittent chattering (bouncing).
I took the relays out and replaced them with home brew solid state transistors small hand wired boards..
Ground based 5 Watt Tx
Yep FIVE watts and range was a problem !
I could not get more than about 3 watts from half a 3A5 tube with 67.5 volts battery but had no range problem.

RE: what was your first radio system?
Here's some of my junk from latter days.
Some things you just can't throw out. Somewhere out in the garage is a Rand actuator. Still have some servos from the Cannon radio. This escapement is an E.D. clockwork and about the same size as an alarm clock. First propo was the PCS. I threw in the Spektrum rcvr just to give you a relative size of this stuff.

Yep, about 1960. First real successful plane was the debolt Trainer on reeds with rudder and throttle. A lot of miles on that one.

Yep. A lot of water under the bridge with a lot of good experiences. Wish I had this DX8X back then. The young Whippersnappers, as Gabby Hays used to say, are spoiled rotten.
Gabby who???

RE: what was your first radio system?
"The servo response time was considerable. "
These kids won't believe this. The time it took for the servo to move after you moved the stick was hundreds of milliseconds - analog propo and reeds too. If my memory is good seems like 300~400. And 0.6 seconds end to end was considered a fast servo. And from 1970 to 1980 20 in-oz was a high torque servo.

I'll have to say that I could give a rat's ass about that .
The one that irritates me is those with 5 or six years of experience
passing out advice !

RE: what was your first radio system?
All readers,
Just my thinkng ___
Years of experience is not an accurate measure of knowledge or capabilities.
In most countries four or five years of studies gives a medical doctor the privilege of practicing medicine, .
Many recent modelers know a lot more than many old timers that never cared to learn more than manipulating sticks on their transmitters.
We need facts and prove them before judging others in our hobby.
Unsubstantiated opinions are just that ___"opinions" that need evaluations.

RE: what was your first radio system?
Radio, transmitters, receivers, electronics. For me a hobby of more than 45 years now.
Picture 1 two channel 27 Mc own construction (first) transmitter combined with superregen receiver. I did use the basic components of this transmitter to built my second I still have , picture 2 and 3.
Receivers also were of own construction but the servo’s, single and dual channel, were of Metz, a German brand.
After a period I did built my first proportional transmitter, picture 4 and 5, circuit diagram “stolen †from Simprop. Printed circuit board and transmitter was own design and construction, shape based on Kraft.
After this transmitter, used for many years I did built a second one, no picture.
After that my new! fourth Transmitter (6), Multiplex Profi Modul, I still use, for about 30 years now to fly most of my planes. I did buy this radio with 4 servo’s 30 years ago, 1600 guilders.
I do design and construct also variometers (7) and other electronics for my models such as datalogging instruments (fuel level, engine temp, rpm, air speed. battery) and cruise (airspeed) control for my Taurus (8)
The picture 8 also shows the pitot tube (Prandtl) for cruise control and airspeed measurements, near the left main leg of the left wing.
Cees.

RE: what was your first radio system?
1966 - Controlaire single-channel "pulse proportional" with Rand galloping ghost actuator- woo-hoo!. Galloping ghost was a big improvement over my friends' single-channel with (rubber-band driven) escapements. First radio with consistent operational performance was 1971 Heath Kit 4-channel proportional radio which worked great. Finally in 1973 bought a "real" radio, Kraft 5-channel (Sportsman?) for about $450. 10 years ago settled on Futaba. Lost of memories...
UPDATE: For those of us not familiar with that amazing 1960's advance of RC known as "galloping ghost" (i.e., pulse proportional), here is a video from YouTube showing the operation of the Rand Galloping Ghost actuator. The pulse proportional RC system got its nickname, "galloping ghost", from its pulsing flight controls. Hey, it worked!

Why did that make me think of Graham Kerr?

They did not use a "galloping ghost" in their cooking.

RE: what was your first radio system?
I knew the ones that were around back then would get it, but those who were too young or not around then would be left scratching their heads.
