Kakute F4 V2 use motor 2 as servo

[holoduke]

I want to use motor 2 as a servo, but this is not working somehow. In the mixer screen you can see id:2 not having a servo assigned.
Motor 3 and 4 are working ok. But if you want to fly a plane with additional elevons you need that extra servo. Is there a way to remap motor 2 to work as a servo?

Short answer: you can't

Long answer: it is possible by making a custom build with M2 reconfigured as a servo output but then you need to use 50Hz for all the outputs

Best solution: Use a PCA9685 board for driving up to 16 more servos through I²C or just use a FC suitable for your application.

Can we really have 16 servo channels that way? Some time ago it was limited to 8 AFAIK.

@Tygrys-1 Should be. The chip and drivers supports 16 servos

Outputs are related to servo ID's and are affected by mixer?
Or it is just direct pass through RX channels to controller?

Goes through the mixer. According to the source code the chip outputs replaces the FC's servo outputs.
