Thank you! The variable voltage is done by tapping into the feedback loop on the power supply. You have to remove a couple of resistors then solder in a potentiometer in their place. It does require taking the board out of the case, which exposes you to the capacitors that could produce a lethal discharge. So I don't recommend this if you don't know what you are doing.

With the DUO chargers, edit the profile, then scroll to the name of the profile, you will see it highlighted. Push the middle scroll button to select. Then use the top middle button, I think it is the tab/sys button, that will backspace and delete the last character. Then go through and name your profile. When done, press the middle scroll button again to get out.

Thx

At the time I made the video a downgrade was needed to get the max discharge rate with the iCharger. Shortly after making the video iCharger released a new firmware that fixed their bug.

I can't say with that particular motor, but I have tested 4 pole motors on my MotolyserII. The RPM will be off due to the two more poles, but the motor ran fine.

@@andrewsarratore5932 OK BROTHER THANK YOU SO MUCH FOR HELPING ME OUT WITH THAT AND THE 550 LOAD MASTER WILL WORK WITH IT RIGHT? I HOPE SO CUZ I'M WANTING TO ORDER ONE FROM YOU MAN GOD BLESS ✝️ SINCERELY CLAY B.

@@claybrown1619 Looking at the Volta 4 pole, I would think it would work. I didn't test any R1 drag motors, just a Tekin and a Maclan.

​@@andrewsarratore5932OK BROTHER THANK YOU I'M GOING TO GET IT ANYWAY MAN BECAUSE I ALSO HAVE BOTH OF THOSE TO THANK YOU BROTHER FOR ALL OF YOUR HELP AND GOD BLESS ✝️ SINCERELY CLAY B.

You can get the max discharge rate of the Icharger with the newest firmware updates. V1.14 The new firmware should work for all banks designed to work with the Icharger.

What would be the max discharge rate If the firmware was updated to the latest version?

@@1dirtovalracer That is dependent on the model of Icharger you have. This doesn't change the models specifications. The firmware fixes the Ichargers not getting to their documented max discharge rate.

I have a 456, 406 and 4010. I use a 4 or 5 resistor battery bank and on my 406 and 4010 it maxes out at 40 amps .

@@1dirtovalracer 40A is max for the 406 and 4010. 456 max is 45A. The problem is some firmware versions of the current Ichargers will not allow you to get to the max discharge rate. This is just a video to help those upgrade their firmware.

Grab my phone stand and do one take, including sneezes, lol.

@@andrewsarratore5932 Perfect!

We have built up the back side of the Motolyser base so the clip keys in and holds it better. We haven't posted any new photos of it, but be on the look out! However, it will only work with WHM Racing Load Master's. Other companies products are not the same shape as ours.

You can connect resistor banks to your charger, but your charger won't get to the discharge rate very fast. I use ichargers and they take about 30-45 seconds to get to the actual discharge rate. Also to see all the data you have to hook it up to your computer. My unit gets to the discharge rate quickly, 2 seconds for a 2s battery at 20A, and all the data is on screen, no need to hook up to your computer.

I think you should test all the batteries!

@@andrewsarratore5932 Brother, I would love to. However, my bank account is trying to keep up with the motors. I will do more as soon as I get time to finish my motor tester and my wife allows me to burn more money on motors.

As always Mr Clegg, thank you for the kind words!

I think I said in the video that the intersecting point was a coincidence. One of the motors I tested wasn't close to that point, also higher turn motors don't follow that trend either. But the drop off should stay relatively the same with different slave motors.

In my video I am using the HW Tunalyzer which regulates the voltage to 7.4V. If you are using a Tunalyzer and getting that much more RPM, then my motor is clearly not as good. But even then, what is your KV under load?

@@andrewsarratore5932 have not done it with load it was the handout motor for the rc chili bowl

@@andrewsarratore5932 I am still learning about the motor side of RC since doing more spec racing

I have parts coming in to make a handful of prototypes that I am sending out for people to test with and give feedback. Once I get the feedback I'll make my final design. I'm not sure on price yet, it will depend on what has to change to the final product.

@@andrewsarratore5932 Thanks Andrew!

Well, it will put the predetermined load on whatever battery you choose. So you will be able to see voltage vs time of the battery. If you have 2 6000 mAh packs, the one that maintains a higher voltage under load is better. So I would say it would work well to compare different battery brands, but try to keep the mAh rating close.

@@andrewsarratore5932 now, if I can convince the wife to let be blow more money on testing more RC equipment. LOL...

Yes it will! I'm going to post another progress video in the next few days, I'll do a 1s test

Thanks Arnel! This project has actually been a lot of fun. Still lots to do, including designing a final enclosure.

@@andrewsarratore5932 It also looks like a lot of work.

Shoot I'll buy one,very nice!

Yes, I plan to add a larger heatsink and fans, plus a cover of some sort.

IR for the motor coils is difficult without a controlled environment. To do it right not only requires you to have your test equipment calibrated correctly, but to also account for the difference in temperature between the motor coils and the industry standard 25C. At the current point in time, it is not on my project list.

Very interesting observation. Now I’m going to have to find time and run some more tests, lol. I’ll try to update the spreadsheet as well.

I'm sure they have some. My 13.5 v21s super short is over 1700, I can't remember exactly how much over, but I was surprised to see it was. But I did send them an email asking about hand picked rotors, and their response was that they did not offer them.

So far a Trinity Copper rotor. Measured at 1767/1745

@andrewsarratore5932 that's the same I received from a Surpass V6. What did your V6 measure?

@@wutupclegg6618 I can't remember the exact measurement, and I didn't write it down. But it was around 1750.

I do have a 550 Load Master on my site. Also just released a 550 Rotor Master as well. www.wmhracing.com

Just realized you asked about the R1 motor. So... I don't actually run 550 motors, I just run 1/10 540 motors for racing. That said, R1 makes some good motors. I generally find they are more on the torque side vs RPM side, but that doesn't mean the 550 motors are the same. I wish I could be more help.

They are AA, AAA, 9v battery clips

I'm still working on the data output. But I plan to have voltage readings every 15 seconds, and an average can be done as well. There will also be mah used, and hopefully I can figure out a good way to do an IR calc.

I think you would be better off using my telemetry module to test the brushed motor. Just hook the brushed esc up to the module like I have the brushless side hooked up. To add, lol. RPM you will need a cheap tachometer though since I get the RPM through the sensors on the brushless motors. But you can use a piece of electrical tape on the couple to create a break so you can read the PRM with a tach, this was how I tested the RPM readings when I designed it.

@@andrewsarratore5932 wow cool. What do they go for?

Well you know, idle hands...

This is my next project on my list after my current project. Hopefully I will have something in the next few months.

Well... I am undecided on using a knob or a touch screen with a slider. I have been programming a touch screen for another project, kind of makes sense to get another use out of it.

@andrewsarratore5932 true, but a knob might be smoother and easier for the fat finger person. Also, if someone is looking for a specific spot. A knob might be better.

I added the link, my ID needs to be verified by RUclips before it is clickable.

@@andrewsarratore5932 Perfect! I love the products. Will be getting the new versions for sure!

For the integrated unit, yes you could use a servo tester. I am actually going to design something into the unit, I didn't for initial one.

I can probably make an option part that is combined into the top. But unless you are pushing the motor pretty hard, it isn't needed.

Yes, when increasing the test motor Kv and using the same slave you will increase the load. I am using brushless motors because most people have some for spares. You want to keep the slave around the same as the test. Higher wind slaves also produce more load.

The problem with using a brushed motor as a slave is brush and comm wear makes them inconsistent. With a Brushless all you need to worry about is variations with motor temperature..

@@andrewsarratore5932 Thanks.

I was a little surprised by the Slot Machine #s as well. I have heard multiple times about timing it at lower values, like 40-42.5. But I also know that one of the faster racers at a local track run it (well used to anyway) at a higher timing. As to the Surpass V6, that motor does look pretty good. I'll run the G4 this weekend, and the next time I go out I'll try out the Surpass.

I'd be curious to know what your experience is using the HW on track vs the others as well. What gearing are you going for?

@grantoverend1, ​I'm going to start with 72/24 and measure temps from there. Honestly, gearing is a guess at this point.

I ended up with 72/22 gearing on the Hobbywing G4. In the main I ran the R1 v21 super short at 72/25. R1 had more punch. Go figure... I turned the same times with both motors, it isn't the motor holding me back!

@@andrewsarratore5932 Makes sense that our driving is the limitation but interesting that you felt the increased punch with the R1. I'd be curious to know how you find that against the Rocket & Trinity. I ran my Slot Machine w red rotor on the weekend at 50° and 78/26 (7.5) during practice. Unfortunately our track had just been re-oiled so grip was not typical but I did like the feel of the motor. Will try it again once track is better.

I have a Hobbywing G4 13.5 that I tested a couple of nights ago. I'll make a video on that. Other than that, I have a Reedy SP5 21.5, couple of Rocket v6s, and a lot of Slot Machines, lol.

Cool, I look forward to the new vids... I've also got a Slot Machine 13.5 W Red rotor, even tho they're banned it would still be interesting to see where their sweet spot is...

You're doing a fine job with your videos! But thanks!

Dude, could you add some of this data to your vids? that'd make your vids even more awesome!

And the Tunalyzer version turned out the best!
