TODO / MEMOs

• ExpressLRS presets might be required after flashing new firmware! 50Hz longrange/Cinematic
• BetaFlight ports -> might be required to be re-anabled (check below)
• BetaFlight PID -> throttle and motor setting -> reduce from 100% to 60-70%. don’t go below 50%

  Batteries

Li-Ion

• voltage, try not to go below 3.0V
• dead limit 2.5V
• ok’ish limit 2.7V, as it is recovers back to 3V ish
• charge current - lower the better. 0.3-0.6A, depending on battery

  RX/TX

ELRS - do it via wifi: power off TX, power on RX, wait for wifihotspot -> password expresslrs or Launch ExpressLRS Wifi TX as well as TX hotspots from TX ELRS configurator app: build RX and TX You don’t have to re-flash ELRS after betaflight firmaware update

Packet rate: 50hz -> longerst range Telemetry: STD Switch Mode: Wide

Goggles

double tap and hold to power on https://rotorriot.com/pages/downloads - range mod

File transfer from Goggles and O3

• goggles - card reader
• o3, connect via USB, no batter required

  BetaFlight

scripts

# HD display
set osd_displayport_device = MSP

# GPS rating on OSD

# soft landing
set exlanding

# DO NOT FORGET TO SAVE
save

Ports

after update RX port might need to be enabled

4.5 notes

via CLI

set osdgp-TODO
set exlanding

• DJI goggles 2 (not o3 unit) need to be on v1.05 firmware
• in order to enable ``` get osd_displayport_device

set osd_displayport_device = MSP ```

Rescue

• Stage 1
  • throttle: set 1275
• Stage 2
  • landing throttle 1230 tbc
  • horizontal speed 5-8m/s, same vertical?
