Hello YUN, I built me also the quadcopter of José, I posed the engines yesterday and to gauge the controllers.
I put the multiplexer of jordi on my receiver, but it seems y to have a problem, I put an oscilloscope at the exit and I do not have screen PPM, the led remains with fixed blue.
I seek the breakdown, I will put the question with José to help me to make it function.
I will post photographs.
