Brian, not trying to be a smart a$$, but if the break-in method you used before isn't netting good results now, why not look at another method? It may very well be the motor, but...
 
For instance, some of the fast guys talk of good results running them for multiple short runs on the track under load. Maybe worth a look.

Should Eric send the 7R motor he won both Retro East races with on Saturday back to JK to put in an RTR car? LOL.

Or Ed Sohl, John Gorski, or Steve Koepp, who podiumed with them this past weekend.


They should offer thanks to the Gods or try to get those things cloned lol. Why do you always run interference for JK for these horrible turds. LOL... they wouldn't podium with the ones I have or many, many others I've seen, not against the older motors.

Recall this junk or at least don't sell this crap. Do as other manufactures have done. Bite the bullet and eat 'em!!
JK has many, many good products they can afford to eat these, instead of screwing racers with turds and IMO hurting IRRA®.
I refuse to run this particular motor and all series should do the same!!!

I have had hundreds of these Retro Hawks as well to be really honest I've only had a handful of bad ones. I can't complain.

 

I didn't want to start **** here just asking what other people have done with the same problem.

 

I do keep running it hoping it will come together or give it to a kid.

John,

 

We are doing just fine with them here in Retro East.

 

Look here at these two charts from the last race at SpeedZone. Look what won.

 

GTC - Top three 7Rs. - Eric also broke the track record in qualifying.

Can-Am winner ran same motor from GTC race - a 7R.

John,
In all the discussion about them, I pointed out, I measured a few, and they measured about 20 pts. higher.

But how come, as I pointed out, they are regularly winning races against old motors?

JK eating the 7R motors?

I just sent him a text to make him aware of this thread.

Be aware this is "getting packages ready for shipping" time, in the slot car world.

I should clarify that the motor issue I described above is the first one I have had out of about 60 or so motors I have had. The bulk of the ones I have are just fine. They make my cars go fast enough that I crash, which has always been the problem.

 

I personally commend Jerry, and now Tim, at JK for providing a decent product for us to use in a hobby that has more complainers than racers.

Try water break in.It sounds like the dry break in is glazing the comm and making the brushes heat up . The water break in will seat the brushes faster and keep everything nice an d cool. Heat will damage these motors so the last thing you want to do is overheat them while breaking them in.The heat damages the brush arms and makes them loose tension.The water break in also helps to true up the comm kinda like wetsanding something as apposed to dry sanding something.Wetsanding always comes out smoother.

Track attendance already being affected. I know a track that has mandated only the new batches of RH with tan-colored etching.


Tracy told me I couldn't run the old motor there again also..mine are at least 2 tenths faster than the new ones..in the flexie class so I quit racing flexie there as another person has also..

JC do you have those 20 or so because they were the bad one form the old motors? No they were the better ones from the old motors so they were faster than the average old motor. 

 

I buy my motors one or two at a time and use what I get or throw it out if it just stinks. So you Hundreds of motor guys carry on.

And I will pay you full price for any that are as fast as my old ones...and you can try to find the golden ones again lol..
No Eddie never got hardly any bad motors at all of the old ones,,
I've done many breakin methods they all work it just depends on if your hurried or not..
these particular ones I tried it all,,didn't matter..

15 hours at 4 volts haven't done that yet Brian I'll do that right now ..thanks.

If everyone is running the same batch of motors, why would you quit?

I don't know if everyone had the same new ones or old ones I have plenty of older ones and at that time no new ones..
If every one has to eat their old motors,,why shouldn't JK eat their new ones.. they created the problem ..

I don't understand the first line in your last post.

If you like racing, buy whatever motor Tracy requires, and race.

Tim should eat motors when 4 of the top 5 guy's used them, to win a race with 25+ entries?(post #30)

Did Parma eat the Deathstars that weren't as fast as the best ones?

I don't agree with jk having to "eat" the bad ones. If he wood know what motor will be a A motor or a B motor or a C motor and so on, he would sell them maker as that. It's the luck of the draw. Should the state lotto or power ball buy back the losing tickets? I see no difference. Not trying to start a arguement with you JC but I think that idea is nuts.

Let's see, who would you listen and respond to:

 

A. Someone who says this: "Tim should recall them and relabel them as turds or be used in RTR cars." No data of any kind is presented.

 

B. Or the data from actual racing (Noose, Mike, etc.) is all positive and shows our motors to be extremely consistent and plenty fast. That's not my opinion or in-house test data, that's actual, irrefutable, independent race data.

 

Me, I'll choose B.

 

Brian, if you have any significant data (not opinions or just one motor) please let me know and we will investigate. Your break-in procedure is not typical. How did you come up with this as optimal? What were you test methods? I would also recommend re-evaluating your gearing and monitor the temperatures on your motors. What you are describing sounds like it could be gearing-related thermal overheating.

 

Are our motors perfect? No. Could they be better, yes, and I'm trying to make them better. Can you sometimes get a dog? Unfortunately, yes, but I"m working hard to make that less and less a possibility.

John,

 

You recently posted a pic of a huge pile of motor parts, for "built" motors, with a string of magnets that looks like a 1/24 model of the Great Wall of China.

 

Why did you need that many magnets?

 

Were you racing five or six times a week?

 

I'm guessing "No," since they actually weren't in motors, and you were cherrypicking through them, because, apparently, you're a "I'll spend a lot of money so I'm sure I'll beat you to the deadman" kind of guy.

 

Did you ask the company who marketed those magnets, to "eat them," because they weren't as awesome as the ones you actually did install in motors?

 

You have thousands of dollars of unused motor parts in that pile, but you are making "turd" comments about JK, because you're "stuck" with $259 of fast old motors, and Tracy wants you to spend $13, $26, $39, or $52 to race with the same generation motor, as his other racers.

 

You're post #42 comment, "If every one has to eat their old motors" is inaccurate.

 

Put your old fast Retro Hawks in the Racer Swap Shop.

 

Since no Retro orgs, that I'm aware of, using IRRA® rules, have banned the old motors, I bet you'll sell them in a hearbeat.

I got the break in idea from two people. Willy Cluster and I spoke with Tony P which I'm sure has forgotten more about motors than any of us will know.

 

My gearing is the same as everyone that's runs Can-Am

Guessed wrong, Mike. Those magnets were all cherrypicked before I got them..

 

Nothing in those pictures cost me a penny either, nor did tires, nor did bodies, nor did chassis... or any other slot part. For 20 years..

That's the reason I raced at over 100 raceways... won many national events in all the scale classes...

 

Bragging? Yes... that's my data..

 

Tim, I know you are doing the best you can, as Jerry did. China stuff is cheap Chinese stuff period... they are not at all mindful of our slot car motors / automobile mirror motors / whatever else.

I'm not stuck with any old motors we still race them at different tracks... but it seems some track owners are headed that way... I can surely afford $14 motors... LOL.

 

We run PS4002FK in Can-Am and everyone is more than happy with them. Only $1 more and etc... etc...
