Yes mine were super-bright! I went ghetto with mine and jut put a small dab of paint over them. Fixed that pretty quick. It's a great tool to have in the tool box. I use mine to test esc and motor too, just make sure it's on manual mode beforehand.
Yes, the LEDs were impossible to look at. I have replaced the resistors the fist evening I've got it. I would bet the processor inside also appreciates much lower load. Other than that, it is great!
If you look inside, it's just a microcontroller with crystal, a potentiometer on the adc, a button on another input, 3 outputs to leds and one output to output. Plus some caps/etc. I'm not sure if there was a voltage regulator in it.
I assumed is 556 dual timer chip inside, but the code was washed out ady. Sorry. In my opinion, you will not get the schematics, or else the Tester has no market value ady.
A 4-5 cell Ni-mh or Ni-cad will power the servo tester and servos. In a pinch connect a battery to a ESC with out the motor and connect the ESC servo wire to the input of the servo tester this will provide 5v
Hi all,
Could someone please describe the IN port labeled as " - S" on the module? Does it mean I could input my own PWM signal from here in MANUAL mode instead of adjusting with knob?
Your helps is appreciated.
Regards,
Mehmet
The IN and OUT ports are labled -s for the three pins. The battery goes in the IN port with the and- lined up, and the servo goes in the OUT port. Why they put an S pin on the input side, I don't know. You could try putting your own signal through it, but I don't know if it will do anything.
Is it possible to test 2pcs servos with 2500mA each simultaneously? Can the servo tester withstand 6V * 5 AMP ?? Where is the limit regarding current through the part??
of course... if you have an opto esc you need to stick in another esc that has a bec so you will have power and when you plug in the esc have the tester on max . two beeps and you take it down to minimum then your esc will know what is the max power and minimum power. only beware not to press the round button accidentally and then connect your motor it will be on auto and then you can have a disaster of your motor turning on and off with no control. car-full !
Ya it was an old email of mine so it poped up automatically when registering i didn't choose it. it was made for the political strive to make love not war.
NO. I have the same servo tester and I use a receiver power pack. It is simply a plastic battery holder that holds 4 AA batteries and has a servo lead connector that plugs straight in. & - only required. Buy or Make your own.
I love this tool. You can check servos for jitter. I use it all the time to get a center when installing servos. The lights might blind you though. I point mine another direction. They are really bright. No shop should be without this device.
This is a "builders" tool. It is mostly used for finding the servo center so that you can attach the servo arm/wheel before putting the servo into your heli or plane... you can also check for binds in your linkage set up and also find what the travel limits will be without the use of your tx or rx... Must have tool for the serious builder, even if you only build one or two machines a year!!!!
Awesome item hobby king has cheap prices but they make up the shipping weights to make there money back so people think they get a deal but the shipping prices are insane I weigh some of my products after they arrive and they are much less than the site says now I try to just buy from us warehouse now that they add a lot of stuff but they won't add certain things that weigh a lot so you have to pay a great shipping to get the item if you really want it
Yes, you can use this to control the ESC as long as it requires a standard PPM servo input signal (like nearly all stock ESCs do).
Just be careful not to activate the "neutral" or "autocycle" mode because this would start your motor without rotating the knob.
I am very new and just starting my first RC project, its for my final year project (electrical and electronic engineering).
so, I am building a prototype consisting of:
1- Contra Rotating BL System 375W
http://www.hobbyking.com/hobbyking/store/uh_vie wItem.asp?idProduct=6565
2-ZIPPY Flightmax 4000mAh 3S1P 20C
http://www.hobbyking.com/hobbyking/store/uh_viewIte m.asp?idProduct=7634
3- 2 Turnigy TY-P1 25Amp HEXFET® Brushless Speed Controllers
http://www.hobbyking.com/hobbyking/store /uh_viewItem.asp?idProduct=17135
4- Turnigy Servo Tester
I want the motor to lift itself , the battery and the circuitry, so lets talk electricity; are my choices correct ? safe ? will anything burn ? The motor draws about 30 amps (17A*2=34A)and each esc can handle 25 amp, so how ?
The real project will use sensors and will execute built in programs, so it wont be an RC, but more of an autonomous machine.
Please help, and thanks in advance
Apparently does not burn anything, regulators are excellent and constant load is normal. In addition, regulators can withstand higher peak load. Selecting the battery is only good if not included in the model because it is heavy enough :-)
How do you connect a lipo battery into one of these without going through the ESC's BEC? like 1s has 3.7V and 2s has 7.4V, and they are both outside the range of this tester.
Unless you have a voltage regulator you can´t connect a lipo.(thats why we use the ESC) Use Nimh batteries or a old power adapter with with correct voltage within the range and the thing(servo/motor) you are testing.
Easy speaking, any power sourse (DC) will work if voltage correct and not too little amp.
I bought a 4xAA battery holder from Radio Shack and added a servo connector to the power leads. This is what I use to power my tester and servos when I don't have a BEC available.
*ant-dodger, any source that will supply a voltage within the voltage range of your servos will be suitable. Most servos are in the 4 to 8 volt range so that should be just fine. Just make sure that you get the connector right.
thats what I actually mean: does the connector of the battery fit in or not? I'm not only sure about connector types. The best is if I open the stuff and plug in without any rework. If the connector doesn't fit what type do you normally use to provide the fit?
I did not have a chance to look at that specific battery pack but if it has the standard servo type connector, then yest it will fit. Just make sure the polarity is correct.
For my battery pack I soldered on one half of a servo extender for my connector.
Thank you very much guys, but I need to be able to revers the dc motor just like a servo, or find a very quiet servo which from what I've heard, they don't exist. I've seen some of the videos where they use this servo tester with dc motors, but I need very slow speeds. If anyone can refer me to the right place I would appreciated...........Thanks
a servo tester or servo driver takes in dc power and outputs "Rc Pulse signal (PWM)" this means if you hook a servo into it it will feed the servo voltage and a pluse signal aloowing it to be positioned as if hook up to an rc radio. it is not capa ble of running a dc motor. it will however drive a brushed speed contol wich can run a dc motor.
The other option would be to modify a servo for continious rotation. when hooked up to a servo driver can be run a a variable speed motor and you can u
Hi hobo, you can't control a dc motor with the servo tester since its output is 3 wires - ground, signal and VCC. To control the dc motor speed you need a simple variable resistor(Potentiometer), you can buy it from any local electronics store, be sure to match the power dissipation of the resistor with the motor power
hola, con este aparatito puedes revisar de forma segura tus servos, tiene tres modos, "manual", que a medida que giras el potenciometro se mueve el servo, "automatico", el servo hace un barrido de ida y vuelta todo el tiempo, "punto medio", sirve para encontrar el punto medio del servo, para poner los brazos, etc. cuando tu servo esta roto, lo escuchas y ademas ves la falla en su desplazamiento!!!
Can I use this to control a motor? Not a servo.
Actually I need to be able to control two small motors at very slow speeds and be able to reverse them. Can anyone help me with this?
You can, just plug th chanell ( from ESC) to servo tester ( as you plug servo to test with it). Don't forget to supply power to servo tester ( I use battery holder for that) 4 x AA Battery Holder (Rx Pack), or another BEC/ESC for power.
Hobbyking have made a very good video how to hook up to control a motor. can´t write link because it will get censored but you will find it with little bit of search
i have a continuous rotation servo wich i made and i want something that i can use to control this servo. i have built a dolly rig and want to move my cam very slowly to do time lapse now using my 9x the servo is very smooth but i want this rig to be light and dont want to atach a transmiter to it so wonderd if a servo tester would do the job of going very slow for a very long time then doing the same the other way.
You have to make a circuit with a timer like the 555 (integrated circuit), search in the web. There´s many project´s using PWM (pulse with modulating). Search in electronics aplications of timer 555. Good Luck!
I have used it with continous rotation on a kap kite. you turn the know on way or the other and there is a variable continous speed. somewhere in the middle will be a stop(the stop is ajustable if you hae made your own continous rotation servo by ajusting the pot inside it

EXACTLY as advertised.
Makes setting up a plane or testing a servo easy!
You have your choice of 3 modes.
1. Manual using the knob
2. Neutral which will take your servo to it's neutral setting automatically
3. Auto which continuously cycles the servo limit to limit.
Will it replace your $100 servo tester....probably not but for everyday use it's great.
You won't be disappointed in this one.

Useful little unit, has three modes identified by three blue LEDs that will have you seeing spots they are so bright. Neutral setting is useful for getting your servo horns centered without trial and error and the third option cycles the servo continuously. A few minutes will help seat and quiet noisy gears in new servos.

Nice, simple and does the job. Has 3 servo outputs that all get the SAME signal.
Has three modes: 1. Manual - set position by adjusting knob. Good for cheking how servo controls surfaces. Just be aware, that some radios/receiveirs can issue a wider travel range, so don't rely on this tester to show your servo's maximum travel. 2. Center - for aligning servo horns. 3. Auto - scrolls servo forth and back at constant speed. One period ~= 2 seconds.
Super Servotester,stabieles alugehause,mit 3 servoanschluessen paralell,einem jr stromeingang mit 4,5-6,0 volt. es besitzt 3 automatische funktionen 1-neutral-servo mitte 2-automatik-servo bewegt sich vom re.zum li. anschlag 3-manual-servo wird ueber ein poti bewegt. fazit und praedikat sehr empfehlenswert... ciao Piperpaule www.mfc-thiede-vallstedt.de bis bald.....

A very good Item for a low price. The neutral setting is the same as on my MPX-transmitter. It is very good to adjust your servo before installing in the model. The blue LEDs, however, are much to light. I have paste over them with a strip of tape. Then it is ok.
