World Radio Blue Max 4 channel kit radio. Built the radio and all the servos. Later I bought a Competition Series Single Stick 6 channel Pro-Line and two RX. One RX has never been used. I also have an Ace Silver Seven Single Stick I built from a kit along with all the servos, but have not flow that system but 5 times.

First RC was self made Heathkit (don't remember how many channels- year 1971) with 3 huge servos (motor, rudder, elevator)! Progressed to a Cirrus (actually a Futaba or forerunner of Futaba?) 6 channel with servo reversing. Still have the radio and it still works! Nope, don't use it- just take it out once in a while just for memories of the good old days.
Heathkit is long gone. [&o]

In the mid 60s I built a single channel escapement system from a kit, I don't remember what brand. Push once, left rudder, release and return to neutral. Push twice, right rudder, etc. Escapement was powered by a wound up rubber band.
The plane it was in flew off into the sunset (literally) on the first attempt and we never saw it again. Back to U-control.
Next try was in the early '70s with a pulse proportional system, single channel, this time the plane landed on a neighbor's roof. Back to U-control (again).
Finally in the early '90s I bought a Futaba FP radio and was able to actually make the airborne plane respond to inputs, up to that point everything had been free-flight. Even though radio gear was installed it had no effect.
It probably would have been easier if I had had a little money to spend on decent radio equipment.

MRC 4 channel with the white transmitter. The receiver made it through four crashes when I was learning to fly before it quit working. Actually the four crashes was my first four flights. That hurt!!

First Radio was a Single Channel (Carrier Wave)
Citizenship FL27 TX on 27.255 mh one handed flashlight like only square, so you could hand launch and had a 3 foot 1/8 music wire antenna. Lotsa Batteries like 2 ea, 67.5 volt, 1 ea 15 volt and a 1.5 volt filiment battery.
Matching Citizenship Rx with a rubber band powered escapement. RX was of gas tube and was suspended per four rubberbands from each corner. Also lotsa batteries. A, B and C.
No throttle so you flew till it quit or crashed.
No Instructors just maybe a buddy and neither of you really knew how to fly R/C.
Lotsa fly aways - most always !
Oh, Yeah you needed a FCC issued Citizen Band Licence which was free in those days. Call letters and all.

A tube Wag reciever and ground base transmitter working off 132V converter that would make the hair stand up on your arm if you got too close when I keyed it.
All stuffed into a Rudder Bug with Bonner s/n escapement...Rudder only.
When Bonner came out with the Varicomp escapement I used the s/n for throttle control............hi & low with a tin can flapper over the intake.
I thought to myself......it can't get any better then this??? Around 1957

Early 1969 World Engines Blue Max. I flew off the steel reinforced runways at Lowry AFB and the Blue Max couldn't deal with the environment. Cost me 3 Ugly Stiks before i gave up and bought a Kraft Series 70 4 channel. Came with KPS-12 servos I believe, the small ones. Worked beautifully, still have the radio and still works fine tho not legal anymore. I had several models of the Kraft radios thru the 70s, good luck with all of them. Switched to Futaba Competition 7 in late 70s, have been flying various Futaba systems ever since.
