Betaflight: Issue BF 3.4 16k/16k with blackbox at 4k

[chinoox]

Problem with bf 3.4 16k / 16k with a kakute f4 when active betaflight at 4k vibrates too much and the data is not useful for PID analizer. There is also vibration with blackbox at 2k, but it is much smaller.

The problem is likely that you're overloading the CPU. Blackbox logging at high rates consumes quite a bit of processing power so the combination of that along with running 16/16k is likely too much.
