Development

Updates throughout the development of Britney

10/11 - 10/16

Selection and purchase of parts

10/16 - 10/22

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

11/06

Frame constructed

11/08

Motor characterization experiment performed. Involved measuring RPM with:

1. Constant voltage, changing PWM
2. Constant PWM, changing voltage

Developed plots of RPM, power, and efficiency against the changing parameters.

11/14

Propellers were too big for the gua

Solution: used Dylan's propellers...

Complete construction of Britney

11/17

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.
