      no no the Max.thrust: 3500g of the brushless motor

        ok 

        So to be able to carry 3.5kg you will need twice as much thrust. 

        So do you want to carry 3.5kg of do you need 3.5k thrust?

          what it is the difference between carry and trust

          someone explain to me if a motor trust is 3.5js x 4 motor = 14kg  = the quadro coptor can carry 14kg , how truth is that? as i have saied i am new on this and i do need help from ppl who has a lot of experience on this

           thank you

            Ok so lets say you have 4 motors that put out a combined thrust of 3.5kg and your quadcopter wieghs 3.5kg they cancel each other out and you won't be able to lift off. 

            For an effective machine, you need motors that put out a combined thrust of twice what the entire machine, with batteies and what ever payload you want to carry wieghts. 

            So lets say you want to carry equipment of 3.5kg, you then add the total weight of the machine's hardware and multiply the result by 2.
