Can this be powered through an esc signal cable that is commected to a 3s battery, or does it need to have its own power supply?

  • I used the power from my Q-Brain 4 in 1 esc to give it the power needed (which is the smae limited power going to the flight controller.) All I was doing was calibrating my esc after flashing with BL-Heli. It worked perfectly.

Can I test Servo / Channels individually? or like all other it sends the same signal to all 4 channels?

There are no wiring instructions at all. where do you connect positive voltage, and negative voltage ??? what pin goes to what on the servo? terrible

  • Hello Garry, negative (brown or black wire) goes on the bottom of the connector pins. Light colored wire goes on top. My servo tester works great to test servos or center them for installation. from Greg in Cincinnati

    It's the servo test I need. I like digital screens. Once you play it, it's easy to use.

    Make the good price you should have made. The verification of the signal on the oscilloscope looks perfect.

    Simple and effective Yes, you must provide your own battery to power the device, but this should not be a problem. If so, you are the wrong hobby. When I tried to use a battery that was close to its useful battery, I had a small problem, and the reading provided by the device was far from a problem, but after inserting a fully charged battery, the device responded very well. As with any product, the time the unit is preformed is a key factor.
