This is the rear of the speed passion motor:

Some people did shave off the edges of the sensor connector so it did go a bit further into the rounding end of the hole in the backplate. I have seen one guy who milled the hole a bit wider to add more timing. And not to mention the 10 degree sensor PCB could be replaced by an optional 20 or even a 30 degree version. These had a differen color PCB but a black marker could do the trick....

For sure this was a bad choise to use as a stock motor.....

In my opinion running sensorless will remove a lot of options to cheat.


Well, just to give you a little info, we no longer "adjust" them to get the matching readings. We found out that we could do that just by how each screw was tightened and retest.
In other words, there was no advantage to aligning the hall sensors.

Also, on your example, the motor would of been legal no matter what color the sensor board was. There is no rule against physical timing or even altering the physical timing. The rules are for dynamic timing within ESC's.

To me, the only way to get the "tuners" out of the motors is to seal them and do away with physical timing. The original "stock" motors never had adjustable timing, only mod did. But there was other factors like brushes, twisting, and springs that was able to "adjust". With brushless, you don't. So sealed to me is the only way to have a true spec motor race.

What is the use of blinky if you can adjust timing on de motor? Zero timing does not mean 30 degrees timing on the motor.
That is why with this motor the max 10 dergees was alowed but not more but every degree more is an advantage.
The current ETS Muchmore motor has a fixed endbell which can be ordered as a separate part to mount it on a standard adjustable motor.

There's also a big difference between motor timing and esc timing. Motor timing is there all the time, while esc timing can be phased in as the RPMs increase, which is much more efficient.

The point of blinky is to stop the dynamic timing during acceleration.

Different motors have different ranges of timing also. Some also have a few degrees already set in the motor, so when it says 30 degrees on the can, it is actually 25-35 degrees, whichever way they preset the timing. Some motors only give you 10-20 degrees of timing to work with, others 40+. That is why I said the only true spec classes should use a sealed, non-adjustable motor handed out at events.

I agree that different motors have diffent timings, to be sure all are (arround) the same timing you have to use one brand, one model for everyone like the ETS does.

And that is why I say the sensorless setup is the best option to rule out tolerances and cheating on the sensors.

For big events, sure. For club days, that's overkill.

This is true but unfortunately I think the Trinity spec motor would be a good one , I'm sure their will some verances in the timing marks but probably not enough to make a night and day difference...
And can be a random # draw at big races

Totally agree :)

Sensorless ESCs are still capable of adding timing. They're also not regulated in the same way as sensored ones, since competitive racing almost exclusively uses sensored systems.

Thanks. Assumed that was the case. So the "list" is not really what is used, it's the tech.

Which makes complete sense, as you can run an approved unit, but who is to say the software is approved or hacked by some smart cookie to continue to blink even when some timing is introduced.

Well, my point is you no longer have to be a smart cookie to hack an ESC. One factory I know is already supplying them to consumers hacked.

It seems their version of following the rules only means the ESC must show a blinking light, not why it blinks.

patorz31 12-20-2016 08:45 PM

When hacking an esc making it blink usually involves changing one value in the code from a 0 to a 1. The hard part is decompiling the firmware that only takes a little time and computer knowledge. Once you know what chips are in it finding the language its code is written is fairly easy.

cplus 12-20-2016 10:26 PM

Hence a list is pointless.

And race referees really need to watch for performance differentials and then get the ESC onto a scope.

Still a lot of listed ESC's can run sensorless and connecting a programmer box can show the setting much easy.

If you're going to consider hacked ESC firmware, then the settings reported to the programmer isn't going to be reliable.
