I have an ultrasonic sensor SR04
the way it works is: you send a pulse on the leg, then it will send 8 ultrasonic waves, wait for echo, and then output a pulse on the same leg, the length of the pulse defines the distance measurement.
(you see trig a

Regarding the electronics being fed from one of the ESC's BEC -
I'm on the way of making things very reliable.
I thought of feeding the tronics with regulated 5v, coming from a stand alone circuitry, 5v regulator off the battery.

I'm building a Quad from sketch.
My goals are-
it needs to be stable,
it needs to carry a heavy DSLR
therefore i will go BIG. say around 80-100CM.
I'd like to get guidelines for choosing the motors.
rather higher or lower KV/(rpm/v) ?
small propellers
