Thank you Guys,

the next S/C transmitter is ready to go. OS Pixie Mk2 from Mike_K´s drawing.
I made a few small changes to get it printed easier.
It features selectable S/C compound and sequential emulation on the button, a second button for sequential throttle, throttle LED, low voltage alert and inactivity buzzer.
Jamara 35MHz module for the RF, a Digispark (ATtiny85) with additional P5 for the emulation and a 2S lipo PP3 battery for power.
Works great, no problems.
Thank you Phil, Mike, Ron and all the others for your support and inspiration to let me build such a replica.

A small in between lockdown project:
I still had a 3-D printed OS Pixie case and so I decided to make new Tx using one of the shielded NRF24 modules.
With an Arduino promini, some switches, a LED, a buzzer and a 9v battery it was one afternoons work.
It features full S/C emulation either compound or sequential, a seperate button for sequential throttle, throttle LED, inactivity buzzer, low voltage alert and provision for rubber escapement switch on channel four.
Works great, no problems. No flighttest yet due to lockdown.
