Thanks Wayne, you are spot on.
Every evening, when I go to bed, I think about which models and which transmitters I will take the next day to the airfield.
I did not count my models or transmitters yet, but I have more than necessary (as my wife says).
Everytime I see an interesting old Tx, I simply have to build it.

Hey all. After finding copies of the November and December issues of RCM&E I caught the bug for converting there old "button babies" to 2.4GHz , with using modern encoder boards and using servos instead of escapements. These were alot of fun to convert and very satifyed with the results. Thanks for taking a look!

Hey Phil. These were taken by my old but reliable LG V10 Android phone. I'm better at building boxes then photo documenting them. Guess this means that I need to convert more transmitters so that I can improve my photo documenting Skills! 😉

My next S/C replica transmitter is ready.
It´s a Graupner Standard 20 in blue color. They were avalable in black and blue as far as I know.
The meter is an expanded scale voltage meter. It features full S/C emulation with inactivity buzzer and low voltage alert.
The motor led will be fitted later.
The case is 3D-printed in the size of the actual transmitter.

Very nice frank

Where did the meter come from, that’s a great vintage looking meter.

Thanks Wayne and Ron,

the meter is not vintage at all, it just looks like.
Vintage meters cost a million, so I used this one:
It is available in various voltage ratings

and I used a carefully cut piece of black self adhesive vinyl to cover part of the glas.
The meter is modified to an expanded scale voltmeter using a 6.1V zener diode and a 20k variable resistor.
That makes a very vintage looking meter fo little money.

Frank
