Notes on manufacturing status.

Airframe

Wing

landing gear

• landing gear adapter arrived and safely stored in the red toolchest

• Has to be assembled and mounted to the air frame

Empennage

• horizontal and vertical stabilizers complete

• control surfaces printed, and linkages made as well

• Only left to glue the vertical stabilizer to the horizontal stabilizer and test the servos for control surface deflection

Servo temperature issue

• will the servo going on to eclipse work under 0 C?

  • Aileron servo: HS-311 Servo - ServoCity®, rated for -20 to 60 C

  • 2.5kg Goteck Metal Gear Micro Servo - RobotShop ← servo bought for empennage

  • Rated for -20 C to 60 C

  • Important to be careful just because manufacture says it’s rated for those temperatures that may not always be the case, there’s no warranties or anything, we have to test to confirm they work. Same like how cheap servos don’t always provide the max torque that the manufacturer claims.

  • Pixhawk 6X Autopilot Flight Controller – Holybro Store ← pixhawk operating temp -25 to 85 C. Shouldn’t fly below -20?

Everything Mech is in last drawer in the red toolbox.

flagpoles are on 1st row on mech shelf

Avionics/EE updates

• Harness https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2556133415/Fixed+Wing+2025#Maiden-Flight-Electronics-System-Diagram

• 6s Servo Module

  • efs

  • ee

    • need 1 good board for eclipse

• 6s power module (EFS)

• Single servo driver

  • ee

    • needs 2

  • efs

    • code dev work is done?

• 24-5V buck

  • ee

    • is this ready to fly (fully validated) ?

• EE connectors are ordered, don’t think it arrived yet.

Timeline

• Eclipse Strapdown Test: March 1st/2nd

• Eclipse Maiden Flight Test: March 8th/9th

• another foam plane?

Pilot Training - Foam Plane

• Crashed right after the throw ggs

• https://uwarg-docs.atlassian.net/wiki/spaces/FT/pages/2967011331/2025-2-2+Autonomy+Foam+Plane+Flight+test#Flight-test-debrief-report

• ee to order servos that are rated for -30C https://ca.robotshop.com/products/dfrobot-micro-servo-motor

• we used same prop as houston, see data highlighted in red below

  

• should we calibrate ESC beforehand? if so how to calibrate?
