What is the story? I am told the stator were .01 too short according to Murfdog.

Rotors max is 12.5mm and they were 12.61 and stators were too short by a very very small margin as well per Roars new stator length rule. And that was out of a brand new D4 SS straight from trinity

Here we go again...

Wonder who gets blamed this time.

I meant the length of the stator, corrected. IMO, it was roar approved. If it was not modified and was factory built, it should be legal for the race. And .01mm is nothing to DQ people over. I dont run trinity motors, but I do feel for the racers being caught up in this crap.

so i take it these measurements were consistent across several motors?

Any idea if it was one of their "certified" motors? Wondering if all of them are like this or just the "good" ones...

Here are the new rules as it relates to the length of the stator from their website.

I underlined the continued inspection piece for your reference.

March 25, 2015
ROAR has made a change to the spec motor rules. We would like to make our racers aware of this change. All motors that have been submitted up to this point for approval have satisfied this specification, despite it's absence in the rules.

This is a change to the minimum length of the stator, to align ROAR rules with other major sanctioning bodies. There was no current minimum.

Original language (8.5.4.2): "The overall stator length parallel to the motor shaft shall be a maximum 21.0 mm"

New language: "The overall stator length parallel to the motor shaft shall be minimum length 19.3mm, maximum 21.0mm"

Please remember despite approval, all motors are subject to pre race inspection to ensure legality.

I disagree. I could play that card too even if I decided to modify my motor.


The problem that I see in their rule was that fact there is no tolerance listed.

So I wonder what motor manufacturer got their knickers in a twist over this one? I think it starts with an S.

I dislike like the idea of the slower out of pocket guys getting DQ'd because they show up and their motor is .01 too long and get a DQ. If they want to disallow the use of the motor and allow them to use a different one, fine. But I am told people were DQ'd and done for the weekend. Pretty harsh thing to do to the small guy. Since everyone thought they were legal. People who put illegal rotors, 13.5 stators, remove winds and so one should be DQ'd and sent home. Anyway, I run reedy, so i will never have these issues, but other guys getting shafted because trinity's specs are off is crap.

That's the first I heard of people getting dq'ed and sent home. One of my good friends and local racers was one that was dq'ed running a d4 SS. The motors were not checked until main events. They did not check motors after quals. At least not his

There is a tolerance. Rotor length is 19.3 +1.7/-0.

Rotor diameter is 12.5 +0 /-12.5

That's plenty of tolerance for everyone except Trinity apparently.

So they didnt tech till the mains, then DQ'd him during the mains?

When you play at someone else's court, you play by their rules. Unfortunately, when another motor builder controls tech - they get to choose how they manipulate the numbers.

I will never own a schuurspeed or murfdog motor, ever, after this "mess".

We watched this same thing happen with the race director/announcer...if you were a california racer, the RD would call lappers for you..If you weren't, then you were left to race the lappers when you came around.

I was told directly different numbers - who are you speaking about?
