Quadcopter without expensive ESC? Answered
Well I am new to quadcopters so please forgive me if I am wrong.
Well I am set about to build a quadcopter and was doing a bit of research on the internet and most of them were telling me to get ESC for controlling the speed of the motor.
I want to know if I can substitute it with something cheaper which basically varies the output using pwm input from the microcontroller(something like opamp)
Another question is about motors ,is it a must that I should get brush less motors
We'll I have two options
Brush less 1500Kv motor for about 30$ each
Normal 24000rpm 12v motor for 6$ each
So which one is better and if brushless why so.
Apart from that how much would a completely finished quadcopter wiegh (approx weight)
