It seems while starting calibration, wizard sets brutally neutral point to 1000.
This seems to run motors high speed with Dshot or bidirectional ESCs.
Set test output true, Output range is 1000, 2000 and it is set to 1000.
Go to Vehicle to swap channels (I swaped channel 2 with 4, because ESC cables are soldered in different order now).
Output went to max 2000 and all motors started spinning.
When changing to OneShot125, all min values in Output tab are set to 500us. Why ? 1000-2000 is pretty standard range.
I actually think that 1000-2000 is traditional range that makes no sense in following cases:
possibly also for I2C escs.
I have always though that using 0-100% meta range would be best today, with all those protocols which have very little in common with 1000-2000 uS range.
