🗒️ The Weekly Recap

✈️ Flight Tests:

• Vanny SUCCESSFULLY completed auto-tune

• Noticed thrust loss on Motor 3 after Battery Failsafe → Investigation ongoing.

  • This is (not) expected behaviour.

• CV Landing pad detection works.

• GPS not tested.

📦 New arrivals

• HERE RTK GPS Base stations here.

• Carbon Fiber tubes here.

✅ Open action items

@Mech to send EE basic X-frame layout so that EE can come up with wiring diagrams/channels.

@Anni to look at static load testing

Conall Kingshott look at talking to bryan about composites

Sensor Updates 📏

• RTK GPS?

Motor 3-phase connectors ✅

• 3-phase connectors decided:

  • MT-30 for inner-hub-to-tube connector

    • https://www.tme.com/ca/en/details/mt30-m/dc-power-connectors/amass/

  • 3.5mm Bullet for end of tube - motor connector.

Battery PDB Distribution

• How are batteries going to be arranged in series/parallel?

• How will our board support this layout?

Airside Electrical Layout

• Where each component goes needs to be added to the architecture document.

• Need selection of proper wire gauges, types, etc.

  • https://www.engineeringtoolbox.com/wire-gauges-d_419.html

  • For Battery connections, 8 AWG can be used to handle 75A continuous (maybe a little lower if stranded)

    • Stranded likely needed in order to have the required flexibility

  • For motor connections, each motor draws around 15A (determined when discussing MT-30s)

    • 14 AWG wire (24A) should be enough for ESC connections to PDB
