Objectives:

  1. Confirm everything fits together at the moment

  2. Identify missing pieces and things that are left intentionally empty/ not fitting

    1. Anything that needs further details to progress. Get those details

  3. Identify things that need to be brought up at system architecture

  4. Assign tasks and action items for Week 2

  5. Talk about manufacture and shipping orders

 

go through each assembly and point out issues/flaws/ etc. take notes on it. Bring it out to main assembly for contextualizing each part.

 

LIVE NOTES

quad frame doesn’t have to be square, it’s more important to have balance weightwise than dimensionwise. Rectangular is fine.

Frame is carbon fibre

 

to edit

  • realign spar holes

  • adjust length of CF tube on edge wing piece

  • some mates messed up along the tail spars

  • Center of mass can be adjusted in this model

 

Comments

  • Caution for center of mass: make sure we do this right, caused crash last time

  • Slider option is good

  • Whether or not the servos will have enough torque (rudder etc control surfaces). Using the spike servos. @Andy Meng will check

    • possibly reach out to companies about this

  • Everything harnessing solution

    • not occurring inside the round tubes

  • length of entire frame, test disassembling and putting inside an SUV

  • push motor dirty air. modify the gap between that and the horiz. stabilizer so it’s not super impacted by that

  • arm disarm must be available to reach when props are on

  • parachute deployment

  • vector nav on wings - massive grounding planes. The other antennas are kinda movable, but vector nav antenna is more finicky than the others, so higher priority. sitting in the wings, not in the CF though. linked in the electronics. @Anthony Luo for insight w/ mounting antenna

  • landing gear not a lot of progress, but skids not wheels. building flexibility into the material instead of additional weight making suspension

  • avionics compartment

  • prop guards….. tabled for now

  • The mates are wrong for the spar mounting assembly, top faces coincident

  • Vibration of motors

  • moving the cabin back and forth issues

  • prop guards for the safety of people

  • ESC mounting (on sides of booms). 3D print an aerodynamic pod to cover the ESCs and or the wires. No wires visible!!

  • Green beacon light top and bottom

  • 3D printed junctions for the fuselage cage can be replaced with something stronger. carbon fibre adhesion methods @Joshua Perry

  • making the rudders stiff w/o using cross spars, or at least something that looks cleaner than dowels. Add to the 6 week CAD
