Connecting 2 Firgelli L12 Servos to one RC Channel
March 14, 2013
I am a photographer in Alaska and last spring I started building a rc rover with a camera mounted on it to photograph wildlife. I used the Wild Thumper 6wd chasse and controller as the platform. It worked pretty well and I captured a few awesome images, but there were some design issues. So this spring I am improving upon my design, however, I have ran into a small problem.
In my new design I am using 2 Firgelli L12-50-100-6-R servos to tilt the camera up and down. Now for the problem, when I connect both with a "y" cord to one channel on the RC Receiver, nothing happens.
This is what I have tried to troubleshoot the problem:
-Each L12 servo works flawlessly on its own.
-I connected 2 standard servos to the "y" cord on one channel and they work perfect together.
-I connected 1 L12 and 1 standard servo to the "y" they worked together.
-If both are connected to the "y" and i unplug one, the other starts working and goes right the the position it should be at.
-I have 3 L12 servos and tried every combination of them together, with no luck.
-I tried running power for the servos directly from the Wild Thumper Controller's 5v output and just connecting the white signal wire to the receiver. Didn't work.
-I contacted Firgelli tech support and asked them. They said it should work, no problem. They guy even sent me a video of his quadcopter he built with 4 L12's connected to one channel on the receiver to control the landing gear.
Basically I have tried everything and I have no idea what is going on! haha
So if anyone has any thoughts or has any idea what is going on I would love to know!
My next question is, if I can't get this to work via a "y" cord directly into the RC Receiver. Is it possible to use the Wild Thumper Control board to relay the signal to 2 outputs. Or to rephrase, can I program the board to receive the signal from the RC receiver in one I/O pins and then just redirect the signal out to 2 different I/O pins (one for each L12 servo). If so, how the heck do I do that! haha
I know it's a roundabout way of doing this but it's the only thing I can think of unless anyone else has any suggestions.
