i have the flex rapidfire(it is beast) on a cg2 controller, but sometimes it automatically turns on and starts changing the speeds on the the rapidfire (it goes into customization mode), i do have like 2 different types of optocouplors i have ordered of ebay, but i am unsure where to put them, if somebody could give me a diagram of the flex with the optocouplor that would be good, and also sometimes my y button doesn't work on the controller, or it goes crazy and it keeps thinking i am pressing y, when i am not pressing it, wat is wrong with it, and also where in the controller do u guys think is the best place to put the pic 12f683 chip. thanks for any help
