Trinity changed some of the design after the original design was certified by ROAR.

Mine said the same but it was only the new one.

That describes the V1, not the V2. The ones you got back and sold should be legal.

I was responding to Rick. He was asking why the V1's were not legal.

No, they were asking why the ones that he got back then sold weren't legal.

What the problem with using Epoxy? are they afraid tricks will be hidden?

The HW G4R is going to see a problem with this. There's a lot of epoxy in those motors.

Right?

Hell, they should have just stuck with kV ratings and allowed dynamic timing. But nope, someone must have gone wah and said "we want brushless motors to be just like brushed!"

Here is a quick comparison just with numbers from a Motolyser, milliohm meter, and an lcr meter.
The below is a pic of the original printout that came with my Slot Machine V1 Certified Plus 21.5. And then a printout of the V2 I received. Notice the rotor strength of my "Certified Plus" rotor that came with my original. Yep, 1700... Also notice that the sensor angles are better on the V2, mind you timing needs to be adjusted because it is too high to start off with on the new motor. Or I think it is, I'll find out...

Here are the readings I get from my milliohm meter (Instek GOM-804), using the pt-100 sensor as well to account for the temperature offset to 25°C.

Slot Machine V1 Certified Plus
AB: 55.3mΩ
AC: 55.2mΩ
BC: 55.2mΩ

Slot Machine V2 Race Spec
AB: 55.2mΩ
AC: 55.0mΩ
BC: 55.2mΩ

And here are the inductance readings from a cheap lcr meter, checked with no rotor in the can.
Slot Machine V1
AB: 118.4µH
AC: 116.9µH
BC: 118.0µH

Slot Machine V2
AB: 120.1µH
AC: 119.5µH
BC: 119.4µH

What does all this mean???
Fantom Racing champions the idea that if you can find a stator that has the same IR and slightly more inductance, that stator would be the better stator. Well my V2 I just received has lower IR than my Certified and higher inductance, so on paper the V2 is a better motor. I'll do some load testing and dyno pulls on them later.

Ok... I finally around to doing a Load comparison and dyno comparison between the 2 motors. SlotMachine 21.5 Certified and SlotMachine2 21.5. I used the same rotor in both motors for the tests. For the Load test I used my Load Master and for the Dyno test I used a MiniPro Dyno with the V3 board. I'm not really a fan of the V3 board, but it is what I have. Also I used a Modified HP server supply set to 7.2V to run the Dyno test for consistency.

Interesting to note. Even though the motors looked the same on paper, once a load was put on the motors you could definitely see a difference. The Slot Machine 2 is down in power and torque compared to the OG Slot Machine. I did mess up the graphs on the OG by using MPH instead of RPM, but the curves are the same because it is a function of the revs of the motor. MPH doesn't quite calculate correctly since I wasn't using the roller.

Anyway, here are the files.

The SM-1 is quite better in all areas. More torque and a higher RPM with a lower current draw. I'm guessing I will not be turning in my Certified SM. I'm finding that most tracks don't care which SM you run. Heck, I'm finding a lot of tracks don't even care if you run an outlaw.
