I have around 20 flights on my 680mm quad using this 4 in 1 esc . very happy with it . it simply works . with my KK2 FCB the esc faces to the rear which points the cables towards the correct motors (x config ). the 3 thro' plugs with a single wire do not locate very securely on the one pin so i made a 3 wire plug , spaced to accomodate the pinout in the lateral sense.top product .

yes you can program with Turnigy Card

Actually the default seting is correct for multicopter:
battery : niCD, Cutoff soft, cutoff level low, timing medium
that is default setup and good for multicopter

installed on a 600MM quad. Took off 4 esc's and a power distribution board and assorted wiring and connectors which weighted 168 grams and put this on with connectors and hold downs which weights 122 grams and what a difference. More response, quiet, longer flight time and runs cool, after 7 minutes temp measured 120F. Worth the effort to install. Had to use M3 on M4 and M4 on M3 but thats not rocket science. Cheap as buying 4 esc's and PD board. Motor wires come with female gold connectors
