Sorry - It was a very stupid question - The arrows in the gui are in a different position... Only that..
Hi People:
Today, and after months of reading and figuring me how to do it... I realized that maybe my propellers/motors are not rotating in a proper way.
If you see the MultiWii Conf print screen, the red arrows in the graph are not showing the classic arrangement for an X configuration..... The front is ponting inside, and the back is pointing outside.. a bit strange... and I realized today...... (it's different to the diagrams in the multiwii site...)

But, the original diagrams from multiwii indicate to wire the motors in a QUAD X config in a different way.

Maybe is an error in the GUI... but, who knows....
Do somebody know the correct way to wire the motors to choose the sense and which propeller goes with each motor. ( R propeller with CCW motor or not ?)
My copter seems to fly.. (It is not flying like the nice youtube videos....it's "rustic"...) until now, I had no time to test it well, in a clean site and higher.
Thanks!
Daniel
