Haven't done it the way you did, but I had everything in my G-202 in and plugged, and running the last wing bolt in, ran it through a wire somehow and it caused them to break and touch. It smoked very bad, and you can't imagine how long it took to get all the dumb wing bolts out. Melted all the wiring on the radio and the battery. Luckilly it didn't burst. Trashed 6 servos, 2 3 foot extextions, a battery and a brand new PCM Rx. Sent the RX in to be fixed and threw the rest away. Not a good move.
