For all of you who have bought a three channel radio and plugged your lights in and presto... no on/off for your lights.
I know pics would be easier to follow but my desktop is down so I'm doing this from a tablet so no pics sorry but I will do my best to explain.
What you'll need:
Soldering iron and solder
Old servo
Light controller ( I used an axial light controller )
Lights ( axial lights that came with controller )
Two resistors ( I used two 2.2 m ohm resistors don't know why but it felt right, if your better with electronics you can figure out something better and comment
Why can't you just plug lights into your rx and turn them on and off? Leds have no signal wire just a positive and negative wire. So you need a "switch" that can receive a signal. That's where the old servo comes into play.
Now you could pay ten to twenty dollars on a turnigy or heyok receive light switch or you canmake your own.
Alright first you need to disassemble your servo. Take the electronics board out and cut the wires off the motor. There should be a red black and white wire. You can completely remove the white wire. Take your light controller and cut off the servo plug. Now solder the black andred wire from the light controller to the old motor wires. Black to black red to red.
Next, cut off the "pot" on the servo circuit board. This is a part that has three stiff wires hanging off of it. ( should be the only other noticeable part on the circuit board other than the motor). Now take your resistor and solder one end to one of the outside stiff wires, and the other end to the middle stiff wire. Now take your second resistor and solder one end to the middle stiff wire and the other end to the last stiff wire. Now I'm not sure if it matters but I made sir the color bands on the resistors lined up. For example from left to right the color band should read: first resistor, gold, brown, red. Second resistor: gold brown red. Just an example but you should get my point.
Finally you should be left with the servo lead from the old servo. This gets plugged into the third channel of your rx and your leds get plugged into your light controller.
Now you have a functional on off switch for your lights on your nice expensive three channel transmitter.
Hope that this tutorial is easy enough to follow without pics. I am an electrical dunce and I was able to do it so don't feel like you can't.
Good luck hope this is helpfull
