Fixed Wing 2025
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:
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
