Updates throughout the development of Britney
Selection and purchase of parts
Development of CAD model with all components:
- Frame
- Motors
- ESC
- Raspberry-Pi Pico
- Receiver
- Propellers (Note: arbitrary propeller model included, see Parts List for exact propellers * in final prototype)
- Battery

Frame constructed
Motor characterization experiment performed. Involved measuring RPM with:
- Constant voltage, changing PWM
- Constant PWM, changing voltage
Developed plots of RPM, power, and efficiency against the changing parameters.
Propellers were too big for the gua
Solution: used Dylan's propellers...
Complete construction of Britney
Further motor characterization testing. This time only measured RPM with constant voltage of 14.8V (corresponding to a 4S battery) and changing RPM from 0 - 100%. Developed similar plots to previous experiment.
