is it after using servo testing, esc is calibrated again with RX TX?

[@iskatoysen]

finally full picture of all connections, now it's clear how to repeat this, thanks!

[@ramaraolagudu452]

You are Amazing. Thanks for sharing the information. I'm a big fan of you !

[@robojax]

My pleasure!

[@furulevi]

What about an Opto ESC that has no BEC inside, at 2:15 tha t cable has only 2 wires instead of 3.

[@robojax]

Yes I should I have given example of that. you will need another source of 5V and connect it on the other side. I will try to create a video for that. Thank you for pointing that to me.

[@rolandroth7860]

Yeah this my prob - none of my esc have bec. I managed to power the esc/motor w 3s bat and used a power supply to power the tester. I had the signal from esc and 5 volts to tester all on output side of tester. No love. So you are saying hook the 5 volt to input of tester? What about the sig wire - still to the output side? Thanks man, nice clear concise video.

[@garyvale8347]

helpful video !!!! I was unsure if I was able to use my 3S 2200 mAh LiPo to test my servos with , because the tester states 4.0v - 6.0v range.....but if I understand correctly , as long as I connect the higher voltage LiPo battery through the ESC, ( and connect the signal wire to the OUTPUT side only ) it's OK...correct?....thanks

[@robojax]

Yes you can connect up to 6S battery. To the esc.

[@naveenkumar-hq1bw]

I did the same watmy as u did...but the motor is not rotating...i could a beep sound...!!please kindly help

[@robojax]

Your ESEhas Firmware. The beep has patterns. ONE beep, 2, 3 or more. Each has meaning. If the ESC is not armed (ready) it will not let the motor rotate. So program the ESC and then it will work.

[@elmahdielmahdi6895]

thank you :)

[@robojax]

You are welcome.

[@karlsarte4051]

i connected mine same way but motor will only stay on for a few seconds then it looses power any idea why i cant even go full throttle

[@robojax]

did you change the mode button? put the knob at the middle, check the battery if it is fully charged.

[@francescoranchi7415]

does the servo tester need to be calibrated? is the maximum value on the servo tester's potentiometer the maximum speed/rpm that the motor can spin?

[@robojax]

this test is very basic and has not settings.

[@drewdrew5851]

What is needed to program the esc? I want to use one of these without a receiver

[@robojax]

Depending on the type of ESC, you can download the tools and update it. For ESC with SimonK firmware you can get it from here github.com/sim-/tgy or for ESC with BlHeli firmware use blhelisuite.wordpress.com/

[@XXBearcat]

Is there a way to input signal through the ubec from a toggle switch ?

[@robojax]

the white or yellow wire is the signal wire. does not matter where you bring the signal from. just connect it to your source with one wire to the ground. it will work.

[@merlynrodrigues9180]

I have connected my 3cell battery to the servo tester ,motor ,ESC ,the light comes on 'man' and when rotation of the nob , nothing moves , please advise

[@robojax]

your ECS is programmable. if you do not program it, it will not run. I am not sure which one you have and I have no video on that.

[@Maher-]

Hi , im trying to control a 9v DC motor with a servo controller , the motor is not slowing or being controlled by the controller and its on one speed, what am i doing wrong? Thanks

[@robojax]

the servo controller/tester is for brushless DC motor with 3 wires. your motor has 2 wires. You can use a driver module something like this kzbin.info/www/bejne/Z2jZon-sapVri9k and instead of Arduino you can use servo tester.

[@Maher-]

@@robojax Hi again, i got the servo tester and the mosfet module , i connected signal output of the servo CTL to the signal in the mosfet , i linked both grounds to the 5V power supply and 5V to the output of the servo CTL , everything light up but the motor never turn even if i change the mode in servo CTL still nothing happen, the input for the mosfet is around 9V when i connected the wires to the mosfet and i test the screws holding the wires it dropped to 0.008 but the power supply i warm, is the mosfet damaged?

[@parmveergill1093]

Hello, I'm using a HobbyKing 30A UBEC ESC that needs to be calibrated, i made a calibration code in python but my DT700 motor does not run accordingly, I just bought your servo tester but do you recommend any other way to calibrate an ESC? I'm really confused and have my project due in few days. Please help! Thanks

[@parmveergill1093]

and is your ESC already calibrated?

[@robojax]

Hi, Usually the ESC should work without calibration. Try to set it default. the ESC I used was not calibrated. I have not tried calibrating ESC using scripts.

[@srinivasanm4579]

Can we use the same servo tester For 150cc dc brushless motor ? Pls suggest

[@robojax]

Yes you can. This tester is generating PWM signal which is used almost in every type of motors and servos.

[@newton833]

can i connect a servo tester to a brushed ESC and use it to turn a brushed motor forward and reverse?

[@robojax]

Brushed motor controller should have the control signal. But for this this Servo Tester will not work with that as the values are different.

[@newton833]

@@robojax I found an interesting video on bidirectional brushed esc that works with arduino pwm signal forward and reverse. Worth testing

[@user-hy6lu7nt4k]

good day sir can i ask what is the value of the 6 pin ic on that board? thank you and very nice tutorials

[@robojax]

I have never opened it. Which board? The Electronic Speed Controller ESC or the Servo tester? in both cases they are so cheap, that you never try to make it or repair it. just buy new one.

[@user-hy6lu7nt4k]

@@robojax for the servo tester sir. Thank you🙂

[@carlosogu5196]

Hello: Its possible calibrate ESC with the Servo Tester ???

[@robojax]

yes but not with this as you don't have control over the parameters of PWM.

[@Raja-hv8gj]

Hello dear my 3500kv brushless motor not run...its beeping beeping sound....I have using 40a esc...plz help me

[@robojax]

The beeps are from you ECS. It seems your ESC needs programming. You can send signal if you have this ESC tester. Quickly rotate to the right and then to the left. This will send 1 signal. So this way you can send different signals to control ESC and it will work. Check your ESC brand on google and you will find how to program it.

[@Raja-hv8gj]

@@robojax I have using SkyLiner Esc...how i have program it...I have no transmitter.....I have one servo tester, ESC and Esky 3500kv motor...

[@robojax]

There are 100s of ESC i don't know them. You search your question on Google and I am sure you will get some answer.

[@Dr.HazeFPV]

hello, if i connect a servo instead of a motor can control the speed of the servo with the trigger in auto mode? Thanks in advance

[@robojax]

Yes. This device is actually "Servo tester" I with I have included a servo on the video.

[@Dr.HazeFPV]

thanks for the reply, so just to be clear, if i put on esc and a servo switch on auto back and forth and the knob regulates the velocity? right?

[@robojax]

Yes. this what it does. this is another cheap solutions kzbin.info/www/bejne/npu1h5SlnNFpqtk I have got 2 more videos on different servo tester. check them by searching "robojax servo"

[@Dr.HazeFPV]

thank you

[@Dr.HazeFPV]

what would you suggest, for an application where I need a servo to perform a repetitive motion and where I can adjust the speed and eventually the amplitude of the excursion. I saw the other video, very iformative, but it's not what I'm looking for.

[@techguna8793]

Bro in my esc when I power it up the notification sound was not comming bro but the esc working plz tell the solutation bro plz 😭😭😭😭

[@techguna8793]

Plzplzplzpzl 😭😭😭😭😭😭😭😭 telll me solutation bro

[@robojax]

not all ESC are programmable. Those sounds are from programmable ECS.

[@tomtouma]

My ESC puts out 3.3V. Won't work with these testers. You seen this problem before?

[@robojax]

Yes it should not work. it needs 5V.

[@vivianastridge2167]

You post a descriptive video which is of either no use of very limited use. What are the specifications of the tester , the esc voltage and current rating and most important of all what is the battery voltage and current rating.

[@robojax]

This is servo and ESC tester. Only people use use Servo and ESC will know how to use this . I have another video on Servo and ESC which explains the voltage and current. here I have explained that the tester need 5v volts. the current very minimal.

[@vivianastridge2167]

thank you for your reply. If as you say people who use the equipment illustrated in your video will know just what it is all about, I fail to see why such people would watch your video in the first place. After all even though I am not an electronics person or a RC flyer your video can hardly be considered as imparting knowledge or understanding of an advanced nature . It was my intention to use one of these bldc motors to drive a gyroscope for obvious reasons.While the equipment required is readily available, specifications are most certainly not available for some reason. All or most RC people are quite knowledgeable as far as their craft or hobby goes but that is as far as it goes.There are a large number of videos illustrating how bldc m otors may be run and controlled by the equipment used by RC people but not one single video gives definite specifications, safe operating conditions and requirements etc etc to enable someone who is not overly interested in electronics but wishes to use the equipment for quite a different purpose to proceed with that purpose.. Please give me the references to your material which would be sincerely appreciated. Thank you very much for your reply and all the very best to you, sir.

[@Traderhood]

I am assuming your 3-cell battery is 12V. Correct?

[@robojax]

yes and it does not matter, if you motor is 18V, you can connect 18V to the ESC and still you will get 5V for flight controller or other devices. Today I just posted demonstration of testing servo motor using this tester kzbin.info/www/bejne/inuWip2kqLd4p8U

[@Traderhood]

@@robojax thanks

[@vicomedia1]

the tester takes up less than 1% of your screen ares .cannot see anything .google "zoom lens" then start over and do this video right.

[@robojax]

perhaps you are watching on mobile phone. This tester doesn't have any display to read values from it.when using it, you will turn the knob (which is large) and lights will show the mode(which is bright). You don't miss anything.

[@caribbeanchild]

dude... you're are not saying if to connect to output or input.... just saying "connect here" does not help anyone! some people have no common sense at all!

[@robojax]

Please point the time so I look it. I appreciate your comment. this was very early videos and I learned that I have to make video always for absolute beginner so every one can learn.

[@DiscoverRajivVlogs]

You man taking like kid . You are educated person ,on the tester everything is written like output input etc. It's pretty much self explanatory.
