I hope my subject line is specific enough...
I have 3 Futaba S3003 http://www.servodatabase.com/servo/futaba/s3003. They are powered by a 6V ~1-1.5amp adapter. I am using the standard Arduino Servo lib and I've noticed the servos seem to have a non consistent performance. Sometimes they each move to exactly where I want but other times they are either slow to react or do not react at all. Could there potentially be a setup order to make sure the Arduino knows the PPM? (eg, plug in Arduino via USB, then plug in power source for servos...). Would any plug order even matter?? I have earthed the power source to the Arduino. I just point this out because it seems to be forgotten by many users.
I am using the PWN outs 9,10,11. It just seems like the servos are under powered sometimes. Does this sound right?
