The ZTWs did not have  three wires- just the  signal and -black. I have some of those little red two pin plug and socket which I soldered onto the ubec and  that into motor 1 esc.
Sorted out the  motor  wires to get the correct  rotation and setup the KK2.1.5. Its on "factory settings"  and the  now wonderfully working Devo 10 did its job and so with the help and advice given  here and other threads..the 450 frame is done - to the point it  needs tuning to sort out the flying side.
Its quirky  just now I can  get it up on hover... but its drifts badly - although not wobbly. If I try to counter the drift... it  does a double speed flip into the deck!
So tomorrow will be taken up on you youTube - tuning the KK2.1.5 and Devo 10 stuff.
