Default servo issue

I hooked up a 6v servo to a 6v d/c power pack and the servo arm only travels 5-10 degrees when I push the power button. I need it to travel 90 degrees and stop. Any ideas?

Servos don't work that way. They move to whatever position the signal tells them to. If you're just attaching it to a 6V power source, it's not getting any positional signal. It will jerk briefly as it gets power, then just sit there waiting for a position signal.

If you're not using it with a transmitter and receiver, then the signal has to come from somewhere else... you could use a "servo tester" (also known as a "servo cycler") for that purpose. It is a small box with a knob on it. You plug the servo in to it, and the servo's output arm follows to movement of the knob on the box.

Just want to know.. Can a servo be powered from different source? as long as the signal wire is plugged into the receiver?

Either test the sevo in the car.

Or you need something like this:


Test your motor system without using a transmitter and receiver. The SerCon can be used to test servos and throttle control on ESC's.


* Manual mode: turn the knob with different speed, check the reaction time.
* Neutral mode: make the servo go back to the neutral point.
* Automatic 'window wiper' mode: Servo swings like 'window wipers' to their full angles.
* Connect up to 1-3 servos simultaneously
* Test 1-3 servos consistency.
* Connect 1-3 ESC's & test and compare reaction time respectively.
* Connect 3 servos of the CCPM helicopters and select servos.
