5. Motor shaft diameter = 2.5 mm Dyno shaft diameter = 12 mm
Coupler Design
Motor shaft diameter = 2.5 mm
Dyno shaft diameter = 12 mm
Set screw diameter = 4 mm
Keyway length = 4 mm
Slippage on motor side might be an issue
Developing back up design which will utilize the propeller mount coupler in order to increase the contact surface area

6. Coupler Design

7. Next Steps - Mechanical
Begin motor mount design
Finalize coupler design
Calculate power characteristics of propeller
Receive procured parts
Socket head screw caps, calipers
