How We Spent it

Beyond the tight time limit for this project, the budget was the most difficult constraint to manage. We only had $250 to buy all of the materials to build and prototype our aircraft. This led to us using as much scrap as possible for prototyping, as well as selecting our final actuators in the first week of the project.

Final Budget

Item Cost Quantity Purpose
Pool Noodles 1.78 2 Landing Gear
RC Reciever FS-A86 21.22 1 Communication Between Plane and Pilot
9axis IMU MPU9250 14.59 1 Attitude Sensing
Motors - TMotor F80 Pro 26.9 2 Propulsion
6040 Drone Propellers 8.99 1 Propulsion
50A 2-4s ESC 21.99 2 Propulsion
Raspberry Pi Pico 4 1 Microcontroller
Adafruit LSM303AGR 12.5 1 Attitude Sensing
Shipping 11.59 1
Total 174.23
Final BOM

In addition to having a budget of $250 dollars we were required to keep the final BOM cost of our project around $250 dollars to account for materials that were scavenged or donated. We met this requirement with a final BOM cost of $260
