Introduction

• High Level Specs

  • ~4.5 ft wingspan

  • ~ 5 kg

  • 6S Battery Voltage

    • ~1.1kg of batteries, two 6S packs in parallel

  • Modular wings, modular fuselage

  • Dual flight controller mount

    • support pixhawk and ZP3 mount on the CG as flight controller

• Primary purpose

  • learning how to design fixed wings

• Secondary purposes

  • Custom battery long term? Could be saved for VTOL depending on EE interest​

  • flight testing bench for EE and EFS new CAN architecture. ​

  • testing EFS milestones milestones​ M2 and M3

  • testing EE ZP3 hardware designs

• What it is

  • not expensive

  • not expensive composites

• Frames

  • One for mech

  • One for EFS

• What this isn’t

  • It will just be a more advanced foam plane than we’ve built in the past.

  • This won’t be composites

Electronics

Electrical Components

• Flight controller: Pixhawk 6X

  • Mounted level in central location

  • Vibration dampened but robust mounting

  • Mounting holes are M2, but the dimensions are not in their diagram. You will have to look at the existing mount and/or measure the Pixhawk

  • All ports accessible

  • Useful Resources:

    • https://holybro.com/products/pixhawk-6x

• Power module: PM02D

  • Power leads and white JST port accessible

• ESC: APD 120 F3 or Flycolor 80A 12S

  • Case design already exists for APD ESC

    • This ESC is kinda overkill

    • This ESC is expensive asf.

    • Maybe we sub it with a cheaper one in the future.

  • Expose this to air for cooling if possible

• Motor: AT3530 580KV https://store.tmotor.com/product/at3530-long-shaft-fixed-wing-motor.html

• ELRS Receiver:

  • Antennas exposed, solder pads accessible

• Analog camera:

  • Facing forward, connector accessible

  • Max vin = 40V

• VTX:

  • Should be relatively exposed for cooling

    • Only intended for use on takeoff and landing so while it will get warm it doesn't need super special considerations

  • How exposed depends on what Tx power and on time we wanna use on the VTX.

  • Max Vin = 36V

• Pitot Tube:

  • Need to receive smooth airflow for most accurate data

  • Electronics mounted close enough to connect with tube

• Magnetometer:

  • Mounted level (can be upside down too)

  • Away from metal and radios

  • Away from high current wires

• GPS:

  • Mounted level, away from metal and high current wires

  • Printed text on GPS facing air

  • Safety switch accessible

• Rangefinder: https://ca.robotshop.com/products/benewake-tf02-pro-lidar-led-rangefinder-ip65-40m

  • Mounted level, facing downwards

  • Unobstructed view of ground

• 6S Battery: 4500 mAh LiHV batteries in bay

  • we have 60 of them

  • @Smile Khatri to note dimensions here or link to where the dimensions are

  • Two in parallel.

• Servo module

  • Hoping to be able to use

  • Backup: or COTS alternative.

• Single Servo Drvier
