can't get my 9920 and 9xl setup to work with ubec

[nl12]

I'll get one to try today hopefully, my other spare quit working when hooked up the ubec without pulling the black jumper first i guess i over loaded it? hopefully that didnt damage the controler, i wouldnt think so because I thought BK said U can uses a recever pack in addition to the bec on the controler and that would be the equivilant of bec + ubec i would assume
