My robot has 8 servos, so I bought the Maestro 12-channel.
Of the 8 servos, 4 are smaller (Hitec HS-311) and 4 larger (DS3218). When only the small servos are involved, all works well, but when I get even a single larger one involved, all 8 servers start twitching uncontrollably.
Here is the short video of that happening:
I have a hunch that the power supply I am using, which I borrowed from my son's RC excavator, is grossly inadequate, the label on it says 700mAh / 6V.
Just wanted to confirm with you knowledgeable folks that is what's causing the problem. Thanks in advance.
