Since 1965


I start blog.
My RC life began 1965 with a single button transistorized Tx. Escapement rudder only Cox 049 planes were my trainers. I built many probably about 20 of them. Then stepped up to 09, 15 and 19 with rudder, elevator/throttle electrical sequential actuators.
Here is the 09 engine plane with a nylon prop. Flight preparation and settings were very different from now since there were no inflight trim or throw control at all. At least 20 times of glide path testing and then throw from the top of hill to make turns but with no power. The throttle positions were two or three which were High-Shut off or High-Medium-Shut off linked with elevator so that it could fly like a motor glider after engine shut off. Well, to be honest, my most of flights were just simple as launch up with engine, shut it off then make turns to land. Spent a lot of time for assembling the kit, break-in engine, starting engine and of course repairing beside a few minutes of flight.
The second picture is my last single button plane I flown in 1969.
During this period of time, I had planes flown by it self (lost control) and gone with wind, completely crashed at maiden flight, lost in lake and even stolen.

Those years before 70's, I call " the era of chaos" for RC world.
Single button tone radio became mechanically or electrically encoded "stick" radio. Multi reed tone and Galloping ghost were widely spread. I spectated many elder enthusiasts actually control these radios to fly planes very smoothly. But I also observed they were struggling tuning the radio wearing earphones. These radios are all gone with those people.
Unfortunately I couldn't try these radio systems mainly due to my financial reasons at that time. Well, I couldn't put up with it anyway

70's opened the door of RC world to every hobbyists.
PWM radio system enabled handy proportional control and standardized RC format. Were those all compatible each other?
Servos were not at all while Txs were quite close to be compatible. The Rx/servo connectors were all different by manufactures as far as I experienced beside 4 wires servos were more common at that time (Negative, Positive +5/2~6/2v, Positive +5~6v and PWM Signal). 3 wires servos were introduced later and they are still useable for current system but the connectors were not compatible in early years either.

I don't recall when but JR type (center positive) without directional guide connector became a sort of standard while Futaba still keep the directional guide since they shifted from G connector.

My first helicopter


Back in 1974, I decided to try RC chopper. It was the made in Japan official copy of "Lark" which is called "Dove".
"25" class motor and fixed pitch rotor but did not go up to sky. I kept it for 6 years and finally gave up.
