Add more mix channels

[torandi]

If possible, it would be very nice with more mix channels. In a dual motor setup, with dual steering servos. Having 4 mixes would allow differential mixing.

Maybe something that could be a build option, sacrificing something else? (I'm a developer myself, and happy to implement it, but I'm not familiar with this code)

Yes, more mixes would be a nice enhancement. However, the memory inside the i6 MCU is scarce, and we have already (ab)used the memory for models #15 to 20. Also, FlyPlus is not a complete firmware rewrite, but instead binary-patched original firmware. So we would have to disassemble and rewrite the whole mixing code.

Hi, Yenya. It is a great work what are you doing here. It would also be very interesting for me to have more mixes. I am also a developer, but I am not used to working on this type of project. I have taken a look at the sources, but from your previous comment I understand that there is no specific module for mixing, you would have to disassemble the existing one and then try to modify it. Anyway, if you think I could help in any way to try to make this possible, please let me know what I could do.
