First, congratulations to all the racers and to Mike McMasters for putting on another fine R4.
 
The results are in for the Coupe handout R4 race. Last year used the Hawk Retro motor. This year was the PM motor. Lets see how they performed.
 
Bottom line, the Hawk motor was faster and maybe more importantly, more consistent for closer, more exciting racing. This has been the goal of JK Products^® motor development program for two years now and the results are in.
 

 
Qualifying:
The top 15 racers qualified almost a tenth slower than last year. Furthermore, the difference between the first 15 racers was over half a second. Last year this gap was under a quarter second. The variability for the Hawk motor was less than half the PM motor. While the absolute speed comparison from year to year could depend upon track conditions, the variability of the results should not be affected.
 
Conclusion:
The qualifying was not only faster, but much closer and consistent using the Hawk Retro motor.
 
Racing:
When you look at the racing results, again, the Hawk motor proved faster and more consistent. The top five racers completed two more laps last year using the Hawk motor. In addition, this year there was a 16-lap difference between the first and fifth place finishers. Last year, that difference was only six laps. There was faster and much tighter racing at the front using the Hawk motor.
 
What about the rest of the field? The results are similar. The top 15 racers completed five more laps using the Hawk motor than this years motor. Also, there was a 33-lap gap between the first and fifteenth place finishers this year. Last year, that gap was only 21 laps. The Hawk motor was faster and more consistent leading to much closer and exciting racing across the field.
 
Conclusion:
The racing was not only faster, but much consistent and closer using the JK Hawk Retro motor.

Tim,

 

There weren't any complaints with last year's hand-out motors. The problem has been with newer, blister-packed motors.

 

What did you figure out from the defective motor I sent you a few months back, where an older endbell/brush combo immediately fixed the problem.

Hi Tim,

Just a heads-up this was the Coupe race, not Can-Am. Interesting comparison between lap times and total laps of the two motors.

Can-Am qualifying is taking place now and so far the top five are faster than last year. Some of it is possibly track prep, moto,r or just a combination of both.

[MattD]

Hopefully we will see the same graphic comparison with the Can-Am race, too.

[MSwiss]

The comparison Tim made was for the hand-out race, where racers were required to, of course, run a hand-out.

 

This year's Can-Am race should be faster, as guys can run from any past runs of Retro Hawks.

 

Last year they were required to run hand-outs, which ran great.

[Greg VanPeenen]

Different day, different year, different track prep, different weather, nothing exactly the same as the year before. Very unscientific comparison to say the least. To be a realistic comparison the races would have to have been run on the same day under controlled conditions. Nice try though. LMAO.

 

Lets have a real test. Five 7R7R JK motors and five PM motors, randomly picked from distributor stock. Same break-in time and method. Tested on the same track, same power, within an hour in the same car with the same body and the same tires. Same controller with the same settings. Same driver. As controlled conditions as we can get without doing the test in a climate-controlled lab. Run the motors x amount of laps and average the times. Compare fast laps and average laps. Then do the same for each group of five motors. Then see which motor rules supreme.  

 

Who would be up for that?

Classes are completely different. It would have been a great comparison but...

[MSwiss]

The classes are the same.

 

They are both from the Pro Coupe races.

[DOCinCanton]

As much as I respect what you are trying to do for the slot car industry, I think that your post was not necessary. I think that most or all racers will agree that compared to last year's 7R handout motors the JK motor is faster than the PM motors. I don't think that this is in debate. Heck, I am still running 2 of the 6 handouts from last year. IMHO, of course.

[Terry]

Wow!!! So many things could be said about this post from you Tim.

 

This is nothing more than a feeble attempt by you to save face.  If you just would have listened to the many people that tried to help you, this likely never would have happened.

 

It doesn't matter what the times or lap totals were last year or 3 years ago or what they are next year. What matters is what they are that day in that class, nothing else.

 

I would suggest you go back to work, make a better mouse trap.

 

What's done is done...

[James Wendel]

Well that was certainly nasty, Terry.

 

Perhaps you and those who "like" your comment should reflect on the wisdom of publicly attacking Tim, who works to provide superior products to support our niche hobby.  

 

Would we be better off if he decided that he did not need the abuse of ungrateful customers and left the industry?

[MSwiss]

James,

Considering the level of abuse, Tim has dished out to racers, and raceway owners, who have tried to point out the issues with the latest Retro Hawks, I consider Terry's post very diplomatic.

[LindsayB]

From a stats perspective I am not sure you can draw the conclusion that this year was better than last year - If you take away first and last and look at the spread - last year had both a closer qualifying average and closer lap totals in the race.

 

I am confused at what we are trying to imply.

[LindsayB]

I appear to have misread what has been presented and now see that last year was the hawk and this year a different motor. The stats point to last years motor being more consistent. I am not as concerned about comparisons in lap times and laps between the years - to me it is when you remove first and last and then look at the remaining deviation last year seemed much better. 

[TG Racing]

Lindsay, The problem is with THIS years 7R's.  The batch from last year were great.  If we would have used the 7R this year the deviation would be a lot WORSE!
