Dear IRRA BoD,
 
I have heard that the IRRA is considering approving a motor(s) after the RetroPalooza Race in June that does not follow the current IRRA Specs for Approved Motors.
 
As a motor manufacturer, If these specs are going to change to allow hard Neo magnets, ball bearings and different wind Specs, will this soon be announced to all of the other motor manufacturers so we can consider producing and submitting motors for future approval?
 
We would be more than happy to produce and supply a consistent performing motor based on the new specs.
 
Thanks,
 
Roger Schmitt

I am questioning why and how the IRRA is considering a motor when nothing has ever been posted about a submission time for new motors to be submitted to IRRA for testing and approval. Seems kind of strange that this is happening to me - anyone else?

I have absolutely no interest in Retro racing anymore, but, if I recall correctly, the IRRA has had to modify its motor specs in order to accommodate the motor manufacturers' lack of quality control.

While a motor change may not be popular with some, the majority of racers running JK Retro Hawks right now would probably welcome a change.

 

The problems with the RH haven't seemed to go away. Phasing in a new motor would be a good thing.  Especially if based on the Mid-America Retro Eagle or Chicagoland Stage 2. Retro racers would be more than happy to have a motor with brakes that can withstand heat during a race. 

 

So if IRRA can open up motor submissions based on the specs of one of these motors, I could support that. The hard Neo mags seems to be the medicine that could cure the braking and two-step problem.

The board would not be required to open submissions for motors. They could look at the motors on the market and select from that. At that point in time they could open discussion on the chosen motor or motors or not.

IMHO, the OP has a reasonable request, I hope he gets a reasonable answer!

Interesting, hard neo will be better, but have to be careful with too much brake and torque.

Larger air gap maybe.

BB definitely a good idea, like the B52 motor.

Maybe more $, but anything is better than spending $150 to find a couple of fast motors, LOL.

I don't race IRRA so I don't have a dog in this hunt.  However, we have been trying out these new motors as they are released to see if they fit in our programs. 

 

Our experience with the Chicagoland motors has been uniformly excellent. The 40,000 rpm CR2 has plenty of torque and great brakes. The power curve we found to be very driveable, both for our bank track as well as on the flat track. Each end of the motor is open for oiling. If and when our NorCal Retro program revives, this motor would hopefully be considered as a candidate.  

 

We have also had excellent results with the Chicagoland CR4 (55,000 rpm) and CR5 (65,000 rpm). The CR4 is really fast and really fun on our banked track. It's a good bit faster than a Big Dog with neos, but retains all the important driving characteristics and great brakes of a motor like the Big Dog. We really haven't raced these enough yet to comment on longevity but so far, so good. Also, there has been excellent consistency between and among the motors tested. As for the CR5, it's so fast it's really out of the useable range of the limited programs we do. Maybe this finds a home on the drag track .

 

Our only observation on the CR motor series is that we encourage users to be careful to rough up the plating where you plan to solder the motors to ensure a great hold. 

 

As always, YMMV.

Reasonable? Absolutely so.

 

However... IMHO, it would be better to keep the motor list as short as possible. Also IMHO, one good and reasonably stable supplier would be ideal.

 

Aside: my local track runs a spec 'GT' class patterned after OCC GT1. The Retro Hawks I tried (nine in total) all exhibited either the dreaded two-speed or were just dogs. The proprietor turned to H&R 'Crusher' motors and everyone is a lot happier. 

 

Just sayin'.

This is great news!

 

Are the armature specs the same?

 

65 turns (nominal) of 30 AWG wire (nominal)
• Stack length - 0.390"
• Arm timing - 15 degrees nominal, commutator tied
• Diameter - 0.513"
 

Thanks.
