Now the CPPM pad will be uninverted SBUS/SmartPort instead.
It seems to be a bit of a gamble whether you get SBUS or SmartPort, it might be firmware-dependent.
On firmware 2.1.0 FPort, I actually got the uninverted FPort signal on the CPPM pin, which is what I wanted.

Here are some general INAV tuning tips and things I've learned throughout my builds. Keep in mind that *these only apply to wings* (and maybe planes), not quads:
* There's a known problem with horizon drift. To ameliorate it, use `set imu_acc_ignore_rate = 10`.
* To make turns in automatic turns smoother, use `set nav_fw_control_smoothness = 8`.
* Pawel says that the idea of the software LPF is to replace the hardware LPF. Leave the hardware LPF set to 256 Hz and set the software LPF to 20-30 Hz, with a looptime of 1k.
