Goals and Purpose

Primary Purpose:

• Learn how to design fixed wings → mechanical design skills

• Learn how to operate fixed wings → ardupilot & pilot skills

Secondary Purpose:

• Flight test bench for EE and EFS new CAN architecture.

• Testing EFS milestones M2 and M3

• Testing EE ZP3 hardware designs

Budget and Quantity

Budget:

• Less expensive than fancy composites but more expensive than a small foam fixed wing plane

• Aluminum frame + foam panels

1

• 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

Power Module

• https://powerdrives.net/120f3

• https://www.team-blacksheep.com/products/product:4557

1

• Case design already exists for APD ESC

  • This ESC is kinda overkill

  • This ESC is expensive.

  • Can be subbed in with a cheaper one in the future.

• Expose this to air for cooling if possible

Battery

6S Battery: 4500 mAh LiHV batteries

VTX

https://www.getfpv.com/fpv/video-transmitters/5-8ghz/xilo-stax-5-8ghz-fpv-video-transmitter-25-600mw.html

1

• Intended for use during take-off and landing so heating is not a major concern

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

• Max Vin = 36V

Airspeed Sensor

Pitot tube

• https://rotorgeeks.com/matek-digital-airspeed-sensor-aspd-dlvr

1

1

• Must be mounted level. Can be upside down

• Away from metal and radios, and high current wires

  • DO NOT mount near motors and batteries

GPS

https://holybro.com/collections/dronecan-gps-module/products/dronecan-m9n-gps

2

• Mounted on the wing tips to maximize accuracy

• Must be mounted level and away from high current wires and metals

• Safety switch must be accessible
