🗒️ The Weekly Recap
✈️ Flight Tests:
Autotune works. well.
Vanny is pretty sus atm - however timeline for frame is looking ok for comp 2024 frame.
aluminum and 3D printed joints are flexing a lot
may break on landing or just in flight due to flex
Link quality not great recently…
antennas damaged? still bad when swapped out. 70% quality when above us ~40 m
transmitter on the car instead of tripod
interference from carbon fiber plates and aluminum?
the new big antenna tracking thing isn’t working
get LTE working soon or get a redundant telemetry link
RFD has same issue as at comp.. not the one that went in the water. Get a spectrum analyzer?
📦 New arrivals
✅ Open action items
Conall Kingshott Composites stuff never properly setup, not a problem that we had not given to him, Graeme figuring everything out and then letting us know. Composite manufacturing in the next two weeks.
#electrical: Crimps, connectors, housings, spectrum analyzers, etc.
📝 Meeting minutes
Frame Updates 🚁
MECHANICAL
Composites - Carbon fiber panel mfg this morning
Panels are done
Can be done on the router! No queue for the router, so should be fast
3D printing is coming along
The middle aluminum block is done
Jigs on the way
Priority for 1 drone, 2nd drone will be done either in parallel if convenient or soon after 1st one
Plan is not to wait and see how the 1st drone works, we just move forward with the design
Aidan: we should test before committing to 2 copycat drones (for cost)
better to have 2nd copy even if not fully optimized - most components at least will be salvageable even if some things need to change
most of it is low cost… so probably ok
middle alu block!!!!
Sensor Updates 📏
Two M9N better redundancy with same accuracy.
Will re-test RTK accuracy with tuned position hold & optical flow.
RF updates 🌐
Spectrum analyzer???
Motor 3-phase connectors ✅
MECHANICAL ELECTRICAL INTEGRATION
Found plenty of bullet connectors in the bay
Seems like we have enough, is there a reason why we can’t use the ones in a connector box on the EE shelf?
EE still needs to source Motor/ESC wire
Should be a small task
Battery PDB Distribution 
ELECTRICAL
How are batteries going to be arranged in series/parallel?Scuffed diagram that needs explanation of potential implementation for three 12S batteries
How will our board support this layout?Thoughts:2 PM02D’s (2 banks of batteries), parallel after. Potentially on either side of the battery.Junction point closer to the edge of the board (away from the pixhawk).
Do we have two PM02Ds in the bay?
If so, electrical member needs to test the current sharing capability of the power modules to see if we can get even current draw from each power module
Potentially borrow E-Load from Midnight sun
Airside Electrical Layout 
ELECTRICAL MECHANICAL INTEGRATION
Electrical Wiring diagram experiencing slow progress (unfortunately)
Some of the modules are in the diagram but things need to start getting connected
Power distribution wiring about halfway done
Do we have all the JST-GH connectors (housings) that we need to connect to pixhawk
Took a quick look in the connectors box and only found connectors for 5 pin
Do we need to order more from the other kinds?
