I have mine here in my hands now...
1 is ailerons
2 is elevator
3 is throttle
4 is rudder or batt
Above those numbers are S + -
If you turn it over now so the crystals side is facing you the top pin is signal ( white wire ) the middle is pos ( red wire ) and the bottom one is neg ( black wire )
I suspect you got the servos connections right, but you got the speed controler opperation wrong.
When you want to use the controller to power the motor you dont pulg the main batt into the Rx, you plug it into the speed controler like i mentioned below. there will be 3 sets of wires, the wire to the Rx is ovbious, the other two normally have 2 pin plugs on.. the bigger red female one is for the batt, the black female one is for the motor, at least it is on my GWS control.
If you pluged the batt into this it would have droped the power and all would be happy and safe, i suspect you still had the batt in the Rx and it tried to draw all the power it wanted though it.
IF!!!! your lucky all you've done is break the track between the + or - pins on the Rx as they are not designed to cope with this power.
if you look closely you'll see all the + pins are joined and so are all the - ones, see if theres any break in there, if there is, resolder the joint and you might just get lucky and have a working Rx again.

The rule is, if you have a speed controler, thats where you put your flight batt.
