bk 9920 problem... help needed before returning product...

hi all,
i just have bought a Feigao 9L + warrior 9920 controler, and I encounter problems with it...
I arrive to program correctly my controler, i can hear the beeps then plug back the red caliper on the esc, after that I unplug my receiver and batteries. When I turn power on, nothing happens... i didn't try to invert the motor wires order... do u think i have to try this? it seems to not be a solution...
I tried to modify EPA and trims, but without success...
Before asking this question I've readen many post about 9920, and didn't found anything that could help me.
I've tried to programm with and w/o the bec connector plugged, result is the same, motor does'nt want to run...

Do you think that it could come from my transmitter settings??? my EPA is at its maximum... I use a Graupner XS6-Race...

before trying this system I ran a HV-Maxx system, really more convenient to install, and to program... just a simple touch... after all i'm not satisfied of my new system, I would have better time to buy a new HVmaxx for that price...

Any help would be really appreciated!!!
All thanks,
Fagzz.
