engine problems with arduflyer 2.5

[Skygizmo]

hey have a little problem with my ardyflyer. loaded the quad. have tried to connect one and a motor. all motor outputs works when I run with only one motor connected. but when all four are connected, then works only two engines. checked the solder. only minus and singnal connected on three of the engines. Fourth, all cables. anyone have any idea?
Thanks in advanced

Have you loaded Quad firmware ?
What pins are you using for ESC';s ?
Have you calibrated the ESC';s ?

Post some pictures so we can have a look..   some diagrams would be good as well..

Hard to tell from you post..

Pop into chat and we can talk you through...

Hi Skygizmo and welcome to the forum if you can supply a bit more info like jumpy07 said above it would make it easier to help you 
It does sound like esc calibration though
