ST-R Brushless Help!!!????

[str8up]

Well i got everything istalled today and am very disappointed!! I put the leads on the motor and connected my batts and made sure bec was disabled on esc and hit throttle once and poof went the esc. Smoke came barreling out now the esc is dead. I do not understand why it did this. I hooked evrything up right. The bl motor which is the 8xl did not even try to move. So i am now in the procces of trying to get another mm which will be a while because i am out of money. So frustrated dont know if i even want to find another esc.
