When selecting an ESC for a motor with a maximum current draw of 15A, which rating ensures safe operation according to the recommended headroom?
100A or higher
Exactly 15A
10A - 12A
20A - 25A
Which of the following describes the difference between an 'Inrunner' and an 'Outrunner' motor?
Inrunners are used exclusively for propellers without gears.
Outrunners have the rotor on the outside, generating higher torque.
Outrunners spin at much higher RPMs than Inrunners.
Inrunners have a rotating outer shell; Outrunners have a spinning core.
What all sensors does a basic Flight Controller contain ?
Gyroscope
Accelerometer
Barometer
Magnetometer
How does a brushless motor typically function to propel a drone?
The Flight Controller sends wireless radio signals directly to the motor bells, causing them to vibrate and eventually rotate.
Internal gears expand and contract due to the heat generated by the battery, producing mechanical torque.
The Electronic Speed Controller (ESC) energizes stationary coils in a sequence, creating magnetic fields that attract and repel the magnets on the spinning rotor.
The battery provides constant DC power to brushes that physically contact the spinning shaft to generate rotation.
A motor of what rating do we need to use for a surveying drone of weight 1.5kgs ?
(a)
What does the 'C-Rating' on a LiPo battery indicate?
The temperature in Celsius at which the battery operates.
The capacity of the battery in Coulombs.
The maximum safe continuous discharge rate relative to its capacity
The number of charging cycles the battery can survive.
What happens if a LiPo Battery is discharged under a certain voltage level
we can safely charge it again
It is not reusable
It should be first dicharged fully and then should be recharged
None of the above
Which of the following is a Ground Control Station
