Well… This build I used omnibus f4 pro.
Why?
Because it is:

  1. Cheap
  2. Relatively lightweight
  3. Has integrated current sensor

It takes around 50 mah/km in general. Could be lwss

There are several small FC’s suitable. I used a Kakute F7 AIO in a Nano Talon. That might be a bit large for the dart but the non AIO would work. But nothing wrong the Omni F4 Pro!

Unfortunately I cannot find good alternatives for omnibus f4 pro.
Kakute f7 has no power sensor
Matek f405 wing is a bit heavy for tiny builds.

Kakute F7 has current sensing.

PC3 BATT_VOLTAGE_SENS ADC1 SCALE(1)
PC2 BATT_CURRENT_SENS ADC1 SCALE(1)

define default battery setup

define HAL_BATT_VOLT_PIN 13
define HAL_BATT_CURR_PIN 12
define HAL_BATT_VOLT_SCALE 10.1
define HAL_BATT_CURR_SCALE 17.0

hello! can you share your PID’s?

Well well…
I’d start from default pids and then run autotune.
If you follow recommendations it works pretty good and give you very reliable pids.
Sharing pids isn’t good idea because it depends on many factors and very individual.

Agree with you. On which level you run autotune? Default 6 or another. I run autotune on default 6 level and it not raise P term higher than 0.3, but in manual tune i can raise it to 0.9 for roll and 0.6 for pitch without oscillation

Well… I used default level of autotune.
Also it is possible to define knob and change P, I or D in the flight.
