Hi, I have a TGY i4x (can be found here) and I would like to add a couple of switches to it so that I can drop bombs from my plane. I'm fairly new to RC aircraft and stuff but I was wondering if its possible to add a 2 position switch that takes a servo from its neutral position to fully rotated in one direction (it would be nice to have a 3 position switch that can make it go in both directions if possible). The receiver has 6 output channels but the controller only has 4. is it possible to add 2 switches to the controller, and if so, how do I do the electronics? I'm only 14, and I don't know anyone who is into RC aircraft, so if somebody could help, that would be great. Thanks!
