Zero timing esc's
 

Ok gang, I would like a list of the esc's that meet the following criteria.

1. ROAR approved.
2. Are zero timing.
3. Can not in any way have timing programmed into them.

As a bonus, is there one that meets the above and can run on a 1 cell, without an external booster and provide 6v to the esc (built in booster).

The justock is a zero timing and roar approved. Not sure if there is a 1s version

Yes it is and so is the XR10 JustStock.
I do not know of a 1s version so no bonus points there.

I tried this thing called google.

It gave me a whole list of things

YES!!!:batman:

Yes Google does give you a whole list of sites on zero timing stuff but not the answer to requirement #3. The ROAR list does specify a esc as zero timing but only in some cases.

Hopefully not a stupid suggestion as I'm not really into racing but maybe this?

That has adjustable timing.

To answer the original OP, I don't know of any ESC that meets all four requirements and is still in production-- nothing that I've tested for ROAR in the last three years or so, anyway.

Not even the Hobbywing Justock?

Pretty sure the Fleta Euro has no timing adjustment possible also.

- but - not sure if you are restricted to change the firmware, if you can it can probably do timing adjustment.

Black diamond 1 cell ..in blinky mode... but i think you will need a booster.. its a advanced electronics..

Thanks Howard:
I wanted to compile a list for a specific class. The general idea was I could specify a single model but that can bite you when it is no longer available. So having options was what I wanted and all I want tech to do is identify the esc and not have to know what pattern or color of lights or sequence.
So now the first three are all I need. I will go down the ROAR list again, then check each manufacturer's manual for any indication of a timing method or mode.

It has no internal voltage booster.

The JustStock meets the first three. It will run without a booster on 1 cell but some radio systems need more than 3.7v to operate plus the servo is slowed and weakened due to low voltage.

The only products from HW that can not have timing programmed in are the JustStock and XR10 JustStock. The Stock Spec (both versions) can be programmed with timing.

Fixed timing is getting pretty rare! Since I have all the data here, I just did a quick scan and came up with the following for 2s operation:

HobbyWing Justock XR10
Reedy Blackbox 800Z
Tekin RS Gen2 Spec
Turnigy Trackstar 60A Sportsman

I think there are some older ones (maybe out of production). But you are right they are rare.

You left out the Tekin RS spec.

It has no timing adjustment.

Thanks! I updated my previous posting.

The XR10 Stock Spec 1s has a non-timing profile preset. Timing is locked at zero in this profile. Timing can be added by changing to a different profile. All of this is within the existing software.

Thanks howardcano

That is what i found when i read the manual on the XR10 Stock Spec's. They have a locked mode (as do several others). But take it out of that mode and timing can be programmed.

I guess I need to check closed in tech. I had no idea.

As long as you see the red LED at 0.25 seconds/flash, it's in zero timing regardless of the profile.

Howard: According to the manual on the Tekin RS Gen2 Spec, it has available timing profiles.

Tekin RS Spec has no timing profile options. The RS Gen 2 does have Blinky and optional timing profiles.

The Tekin product page states that the Spec is always in non-timing mode, as stated by yzracer758. But the link to the manual is for the regular GenII, which does have adjustable timing. I don't know if the link is incorrect, or that there simply is no separate manual for the Spec version.

I see now, it is the same manual. Thank you for setting me straight.

Just an update on this thread. The Tekin Gen 2 RS Spec manual that comes with the esc is different than the online one. It states below the shown profiles for timing that the RS Spec does not allow for any of these to be used. The Hotwire software when connected to the esc shows a blank page for the timing adjustments and I believe it states on that page that the unit cannot have any timing profiles.
Very nice esc.

There is a zero timing black box:

No adjustable timing.

It was listed in an earlier post.
