1. A method, comprising: rotating a sensor trigger by rotating a shaft of a motor;sensing the sensor trigger as the sensor trigger rotates to a point adjacent a sensor fixedly coupled to a casing of the motor; andholding a propeller in alignment with a wing of an aircraft by a control signal to the motor;wherein the propeller is substantially aligned with the wing of the aircraft when the sensor trigger and the sensor are aligned. 2. The method of claim 1, further comprising: rotating the shaft of the motor in response to the sensor trigger drifting away from the sensor. 3. The method of claim 1, further comprising: receiving the propeller in a propeller indexer of a hub, the hub coupled to the shaft of the motor, wherein the sensor trigger is coupled to the hub and facing the motor. 4. An assembly, comprising: a hub coupled to a rotatable shaft of a motor;a propeller indexer of the hub, the propeller indexer to receive and align a propeller relative to the hub;a first sensor trigger rotatable with the rotatable shaft of the motor; anda sensor fixedly coupled to the motor;wherein the propeller is substantially held in alignment with a wing of an aircraft by a control signal to the motor when the first sensor trigger and the sensor are aligned. 5. The assembly of claim 4, wherein the first sensor trigger and the sensor are aligned when the propeller is in a horizontal position. 6. The assembly of claim 4, wherein the first sensor trigger is positioned at a propeller offset angle from the propeller. 7. The assembly of claim 4, wherein the first sensor trigger is coupled to the hub at an outer diameter of the hub. 8. The assembly of claim 7, further comprising: a weight coupled to the hub on a side of the hub opposite from the first sensor trigger to weightably balance the hub. 9. The assembly of claim 7, further comprising: a first sensor trigger cavity disposed on a back side of the hub, wherein the first sensor trigger is disposed in the first sensor trigger cavity. 10. The assembly of claim 7, further comprising: a second sensor trigger, wherein the second sensor trigger is disposed on an opposite side of the hub as the first sensor trigger to weightably balance the hub during rotation. 11. The assembly of claim 4, wherein the first sensor trigger is facing the motor. 12. The assembly of claim 4, wherein the first sensor trigger is a mirror. 13. The assembly of claim 12, wherein the sensor is a light transceiver. 14. The assembly of claim 4, wherein the sensor is fixedly coupled to an interior of a casing of the motor. 15. The assembly of claim 4, wherein the sensor is fixedly coupled to an exterior surface of a casing of the motor. 16. The assembly of claim 4, wherein the propeller indexer is a channel having a same width as the propeller, and wherein the channel is located on an exterior surface of the hub opposite from the motor. 17. The assembly of claim 16, wherein the channel is formed through a lip portion of the hub having an angular transition between front and back sides of the hub. 18. The assembly of claim 16, wherein the channel has one or more contoured side walls that prevent backwards installation of the propeller. 19. An assembly, comprising: a sensor trigger rotatable with a rotatable shaft of a motor; anda sensor fixedly coupled to a casing of the motor;wherein the sensor trigger and the sensor are substantially held in alignment by a control signal to the motor when a propeller coupled to the rotatable shaft of the motor is in a horizontal position. 20. The assembly of claim 19, wherein the sensor trigger is at least one of: mounted on the propeller and mounted in the propeller. 21. The assembly of claim 19, wherein the sensor trigger is a magnet. 22. The assembly of claim 19, wherein the sensor is a Hall Effect sensor.
