Making improvements to a new sealed Slot Car motor (Hawk JK Retro) to make it faster 

What do JK and UK Distributor ABSlotsport have to say about this video?… After some questions about running in the motor under water and using different fluids, I have been in conversation with the above and the manufacturer (JK) do not recommend that you use any additive to the water that might soften the brushes. Normal tap water as used in my video is fine, just do not add any other chemicals to it. If the brushes soften then it can cause the commutator slots to clog up with brush dust. Also make sure you do not contaminate the brushes with oil when oiling the end bell bushing as this has the same effect of softening the brush. I tend to oil the can bushing regularly when in use, but not the end bell bushing for this very reason.

Wow I have a lot to learn, I would never have thought you could submerge an electric motor in water without shorting everything out!! Today I learned different,lol

I use straight naptha when breaking my motors in then dry off completely then drop of oil on bearings and race. While running the motor i tend to watch it thru a glass jar/cup and watch for a puff of debris to shoot out of the motor. It varies between motors some after 30 seconds some later normally happens as soon as brushes are fully seated.

Thanks for showing this. A guy in my club has a JK out of the box that's faster than all others. He boasts when he wins everytime. I'll take a look at my motor and use your tips to hopefully crumble his ego. ;)

Awesome work your doing man Fantastic.

Great tip, Did it to a new sideways babyraptor yesterday, the brushes didn't look as bad as those in the video, did the resistance before, it flickered between 7-8ohms afterwards it flickered between 1-2ohm. Great not to need to spend a whole evening at the track running it in. Runned it in batterywater and then cleaned it with IPA.

Love the tools and the knowledge you bestow upon us. Thanks

Nice video. Thank you for sharing!

Simple Green works good too.

Thanks for the help

Hi! I wonder if this braking method works on my used motor great videos! thank you

Those are cool devices

"Dont drink the water" 🤣🤣🤣🤣

What would you recommend for the Mabuchi-style motors that we run in 1/32 scale cars? Your CleaveTech Motor Analyzer looks great, but would it work for 1/32 scale also? How could I order this if it will work? Many thanks!

Good stuff!

Sorry I would use sand paper of different grits like 400, 600 and 1000 to get my results.

Been doing this since 1978 on RC cars, we call it water dipping. The water does not help conduct more current. I holds the motor rpm low from the drag, thus higher current with less CEMF. Before = 21700rpm, After=26500rpm=22% improvement?????? What, 4,800 rpm slower = improvement? Breaking the brushes in, creates more brush duration (aka overlap, 2 pole windings being powered at the same time), this gives more rpm and torque in my decades experience on 05 Mabuchi and Johnson motors. I am really surprised you lost that much rpm (and claiming lower rpm is 22% improvement), thoughts?

I'm thinking about getting into slot car racing. I had a Strombecker 1/32 set in the 1960s. Why do the brushes have that curved where you end up making it straight and a straight area where you end up making it curved? If I looked at that without knowing anything about your process I would say the brushes are installed 90º out of position. They are flat against the curved commutator area and curved against the flat commutator area.

watching your videos is very informative.I am 69 years old and raced for 4 years in the 80s. i am inquiring on your Motor Analyzer ,how can I find one to purchase here in the USA, Bakersfied CA

Where can I get a motor analizer like that one?

I don’t know if you’ve done so before, but I always used a slave motor to break in my motors. No heat through the motor you intend to use. Since you have a machine to test it, I’d love to see some data.

Through the years I've raced Different types and sizes of slot cars, on most of the "inline motors" I would polish the lams (I.E. the plates that the motor is made of were the windings circle). And seam to increase the rpm that the motor run, but never knew what increase I achieved. Since you have a RPM analyzer could you do a test and see the before and after outcome please?

Hi I was told ionised water was best to use, have you used this over tap water? Great videos really helped a lot 👍

22%. 21.7 vs 26.5. That was from a new motor, my question would be what would that same new motor get to just with normal wear and tear racing ? Could you do this same test with a used (maybe newish) motor to compare please ?

Can this method be used for breaking in other chassis. Including non can style. Pancakes As found in some HO stuff, by removing the center top gear. Or the rear drive get in a V1 superG style chassis? 🤔 Great videos thank You.

Back in the day we used to run in rc silvercans in the toilet

1 min / 2volts - i use 1/3 watter + 1/3 benzine + 1/3 Ultra Max Cleaner Wurth solution

You'd think, by now, they'd install the brushes the correct way around!

Great video how do I buy this motor tester and power supply

Great video sir. I would like to know approx. how long you ended up breaking the motor in under water? Also, any thoughts how this particular motor brushes would compare/differ from say NSR or Slot.it motors and whether or not you have experienced similar (22% improvement) results with either of those motors? Last question, by wearing down the brushes, which looks to be quite significant, I assume (possibly incorrectly) that the life of the motor is reduced the same? What's been your experience as far as motor life compared to a motor not run-in this way? Many thanks!

Great video thanks is there some simple way to test that type of motor without expensive equipment?

I've never seen a question as to why aren't the brushes manufactured with a concave face, that would ensure maximum and proper contact with the commutator in the first place?

Where can I find a motor analyzer tester

Can you make a video on how to rewind an armature?

Where can I get info regarding the hardware that you are using? From power supply to motor analyzer.

I just 'subbed'. The motors we run you cannot see the comm's.

How can I get a motor Annalisa

bruschless motors is here now

Buen video compañero, gracias. Do de podría comprar el aparato para medir las vueltas de el motor?. Gracias Nice video mate, thanks. How could you buy the device to measure the revolutions of the motor? Thanks

Can distilled water be used to clean the engine? Thanks

Where can I buy one of those motor analyzes????

Hello friend my name is Paris and I really like your videos I’m in the states New Jersey and I would like to know how can I buy your power supply and motor analyzer and will it work for Carrera one 1/32 and 1/24 scale Motors please message me back thank you….. 🤓

What a bout no a scalextric motor please

I have used the water method on 3 New Hawk Retro motors with the same results, brushes wear very quickly. The most I can run the motor in water, at 5 volts is 3 to 5 seconds, or the brushes will be worn out. I ran one motor for 30 seconds and one brush was worn to the arm. Any suggestions?

Do you sell those motor analyser?

Can these tools be purchased?

So was the water normal tap water or distilled (de-ionised)?

How much?

Did you lube the shaft

Why does the factory install such bad brushes.

Those motors are junk. You have to buy 50 to find and if you are lucky you might get 5 good ones. Then you probably won't have breaks. They are inconsistent. Break them in in simple green. Use computer dust off to blow and clean motor. You or can just leave it on your power supply at 3 volts for 3hrs to 24 hrs

Is this a MOAM brushed eBay gizmo s??? Sounds consistent.

Yes that's a MOAM UNIT . NEW ONES ACHIEVE 100x thou RPMS.

Hawk 7.....junk
