FAQ / ESC tuning resources

Videos

Heat

  • As MOSFET switching frequency increases, so does heat generation.
  • Some reports exist of too hot ESC's/Motors at 128khz PWM depending on the brand/model of the ESC/Motors.

Desyncs

  • Desyncs are typically a factor of ESC settings.
  • Set Motor Timing to a some static value of personal preference. 23 is good for freestyle. Racers typically use higher values.
  • Demag Compensation also a factor but try static timing first, and increase Demag-Comp only as much as needed to resolve.

Racing Considerations

  • Demag compensation low saves roughly 7K RPM (20%) on high kv motors. Although off versus low has minimal effect, some prefer OFF. Thanks to @FreedomDuck for this information. (Ultralight 6S 2100kv to 2150kv.)

BLHeli32 (32-bit)

  • https://github.com/bitdump/BLHeli/releases
  • Some BLHeli_32 ESC's can be flashed with with other firmware, but requires STLink or similar devices and bootloader unlocking. Search for AM32 and/or Escape32 resources on the subject.
