I have a project that I am working on and there seems to be two ways to do it. Is one better than the other? looking at cost and time? I have ordered the motors and am now trying to decide if it can be done with a single speed controller, both of the following ways will need some soldering/parallel circuitry.

The Problem: Control 4 brushless motors so that they are rotating at the same speed, or at least really close.


Solution 1: connect all four motors to the same speed controller capable of delivering the necessary amperage

Solution 2: connect all of the motors to individual ESC's and send the same signal to each ESC.


In my search for an answer another post said it would not work(solution 1), I am not satisfied though because there was no explination of why. The same post also said that if you are using solution 2 you had to disconnect the positive wire(red one) from 3 of the esc's --> reciever connections. Again my curisoity becons the question of why.

Can anyone test this with their own equipment? Does it work? Can anyone explain why it won't/will work? Thank you for any and all input. Lets keep it clean!
