Looks like there's nothing much to capture ... Seems the MCU and the RF are in the same chip, no external SPI bus ...

You only have to move THROTTLE, just after ELEVATOR, in nrf24_multipro.ino, that's all ... AILERON, ELEVATOR, THROTTLE, RUDDER

Seems there's no marking except on the MPU: https://www.rcgroups.com/forums/showpost.php?p=36437721

The Tx might have a separate RF chip on the other side of the board, looks like there's a 5 pin header. edit: no, I'm wrong, the antenna is directly...

Check your wiring, nothing special is required in the code for the i6, many people got the module to work with it already. http://carrerasfpv.com/forums/topic/2986/modulo-goebish-para-volar-los-minis-en-fly-sky-fs-i6/view/post_id/19103

Yes, it works with Futaba transmitters.

Check my answer on the DeviationTX forums: https://www.deviationtx.com/forum/protocol-development/7324-eachine-e013-small-pepper-pretty-please#64843

Fixed.

the #define SPEKTRUM is only for TXs such as the DX4e with limited throw, you don't need it with the MZ-24.

Mapping is TAER by default, same as Spektrum transmitters.
