i guessin a nut shell I bought all the recommended parts, I soldered all the connections, I tested everything I replaced anything that didnt work properly, I even bought a kk5.5 flight controller, a kk2.1 controller, a apm 10 f controller at least 12 speed controllers and 15 motors cuz some didnt spin correctly, broke like 15 props, 2 transmitters, im stuck and discusted.........

Are you running all the motors from individual driver units or multiple motors on one unit?

What is the batteries actual amp hour rating?

What exactly is frying on the motors? The windings?

Where in the circuit were the 3 ohm resistors and what made you think they would do anything beneficial?

RIght now as I see it you would have six motors pulling near 15 amps each of which combined would be ~90 amps so unless your battery is rated at 4 amp hours or more with a honest 25C discharge rating and has wiring capable of handing near 100 amps I would be inclined to say that the system is malfunctioning due to insufficient power.

all motors have there own esc electronic speed control, each speed control has a 3 wire harness that connects it in order to the flight controller, on the other side of the flight controller are the reciever controller connections, roll, pitch, throttle, yaw, gyro, all must be connected correctly,ie withe the black wire to theoutside of the board or it will not function, simple, m1, m2,m3,m4,m5,m6 are motor connections, all motors rotate the correct direction, the hexcopter does everything it is supposed to except take off correctly, trims left right forward back work fine but wont fly

Sorry Bill, we are mis-understanding one another. I am curious, what country are you in?

I wasn't asking you to make a video of your flying machine.

My understanding was this. You like to tinker. You saw some youtube videos of RC mini copters.

You bought some components and assembled your mini copter, and it burns up motors and won't fly.

And because of the observed propeller movement and burned up motors, you believe it is a motor control problem.

With that understanding, I needed to know if you had ever seen a mini copter built like you built, fly?

And I wanted to see that video. The video that you are working from.

Is this your design or from someone else?

The answer to that question will determine if we troubleshoot, or reconfigure components.

I watched many videos on youtube about how to build multirotor aircraft so I learned what flight controllers were popular and wich frames were being used,
ecs's , batteries, and assembly, I just copied what others had done it really is all generic components, there is 1 component that is my design, but its been done by others in a simular way, the power distribution board, the first one i bought had an internal short and fried my motors, esc's and flight control so i made a harness in its place, it is just red and black 16 gauge wires soldered together and insulated from each other to give power to the motors thru the esc's, I checked it with my ohm meter and it has no shorts, I have spent more than 300 hours on a flight simulator before I decided to build one of these and fly it, I have purchased and flew 2 microcopters many times, my dog destroyed one and the other one flys okay but not as good as the oter one did. I bought an syma x5c-1 quadcopter cuz im jonesing to fly more, and it should be here soon
about the propeller movement, I have noticed that if any propeller during hover stopes for any reason for a split second or so, the crafts i have flown will dip in the direction of the stalled motor and will usually flip over quickly. i know the flight control changes there speed and direction several times a second to maintain balance or manuvers but my adjustments dont seem to have enough resolution to fine tune this thing, or its sister the quad i built first.

Show us the power distribution board and your wiring harness.

And your battery specs.

And in your component list.....it shows the firmware list......how did you select the right program?
