I think you have got it wrong. There is a perfect timing for any motor at a certain RPM. It has become very obvious that the SP motors need +10 on the motor to make really good horsepower and torque. I am yet to see an SP motor go good with 0 degrees on the endbell. They do run cooler like that but much slower too... less timing doesn't mean more torque nescesarily, it all depends on how much you already have on there and how much it can handle + what gear ratio you have. Higher FDR means you can have more timing.

Each of my 2S LiPo batt gives me 8.4V when full
So, 15% endpoint would give me 3906 rpm. And only if my ESC is linear between 0 and "all available voltage"

Do you use a voltage sensor to be sure that your ESC is strictly and perfectly linear between 0 and 7.4V? Are you sure your batt gives you EXACTLY 7.4V?

Yes i can read the voltage data,
and even during free rev, the voltage is almost flat.
i was on 7.4, if you read it on charger it's 8.4v
8.4v charge is equal to 7.4v on load/normal. as fully charged is 4.2v/cell on charging volt.
no your rpm at 15% will be 3441rpm, because you read 8.4v on charge checker.
the real Full voltage is 7.4v or 3.6v/cell

I give up !
That's it lol am going back to the XERUN thread, this and the SP one have just become Irgo fantasy land not getting anything constructive done.

Probably because we have zero spec classes all around the world now, which also makes people ask what timing is in the motors, depending on how much this zero spec stuff catches on, may depend on if the next generation of motors all also come with some fixed rate of timing also I guess.
Either that or a timing war in motors...
Either that or a timing war in motors...
I say more timing and a higher gear ratio = more speed?
Am i wrong? This seems to be what the fast (sponsored) guys i race with are doing and they have no problem with torque or speed

Whilst I don't agree with the opening part of your post, I do agree with what you state at the end... it depends on what motor is being used.
Remember, timing on the endbell affects the whole rev range, not a specific part of it.
This come back to there not really being a "neutral" timing standard for motors... i.e. they all come with differing amounts of timing in-built.
Seems the SP motors require a little +ve from their neutral mark (when I ran over a year ago, only ran +5), whilst I know the X12 prefer to run with their "oooo" / -10° insert.
Going deeper, you say that the SP motor's don't produce good power with 0°, and run cooler, well, without timed ESC's, you'd be gearing up up compensate... and thats a sure fire indication of there being more torque avaliable, if you follow. Torque and power are two different things...

To those that say the SP v3 motor cannot be fast unless you run it on +10 - I've had it running very quickly in the middle of the slot, thankyou. It was very fast in the middle of the slot on 518, but dead as a dodo on 119.
I think perhaps that from reading Cherry's defence of the 119 software that I will go back to 518 until we can get some initial settings that are not based on Shinwa motor dressers, guesswork and shouting. As it stands, irgo's measurements of the boost seem more credible than the Hobbywing representatives defence of them - and I never thought I would write that.
#3188
I have posted it many, many times already (although nobody ever seems to notice it) - the SP v3 endbell markings are WRONG. NEVER run the motor on the marked zero, it is actually 10deg retarded from the true zero (30deg mechanical). The motor will never perform on that setting.

We used what we had laying around at the time as I don't have a factory style workstation here just stuff we had laying about, how can using an accurate REV measuring tool be any less accurate than Irgo 'Guessing' what the REVS are by sound, at least I was able to actually 'measure' WHERE about in the REV range the timing actually kicked in.
I actually feel pretty hurt by the comments there sosidge, I have always tried to make myself available to help other racers with our sometime destructive testing, help threads, tutorial videos etc. But if my input is no longer required will just go back under my stone and concentrate on the sales side of things, rest assured that I will keep my future 'self' testing purely to myself and leave you to enjoy the 'what if' wishlists of Mr Irgo.
BTW 'what if' there really was a Santa Claus or 'what if' I could win the National Lottery..

Guys, everbody just relax a bit.
I myself allways keep in mind that everyone is posting with the best of intentions from their experiences and beliefs.
So differences of opinion will also arrise.
Just don't get pissed if anyone is disagreeing. Comments (if stated politely) are part of any good forums.
Thats how everyone learns.
Well keep on testing, racing and sharing.

irgo, if u really want an RPM logger, just wait a lil more for the MT-4. then u can log all u want at your own expense.
stop ur whine and leave the ESC guys to cater to what majority of us needs while keeping their product cost reasonable.

I did some running last night with the Novak Sentry data logger installed (although not much running as someone stopped on the straight... I hit them at 48mph according to the logger, which meant a lengthy repair).
Firmware is 0119.
Motor is SP v3 10.5
FDR 6.5
Track is large (50m straight - top speed about 50mph).
I initially ran with a Boost Start of 3000 and an End RPM (calculated) of 11000. Boost was set to 40 "degrees" and boost ramp to 200RPM/deg.
The Sentry showed that my revs on the infield ranged from about 8000 to 25000. So, I adjusted the Boost Start to 9000, giving an End RPM of 17000. This should have given zero boost out of the slowest corners for maximum torque, and ensured that all of the boost is used on the small infield straights.
The effect on track... nothing, it felt exactly the same, the laptimes were the same, and the acceleration curves from the data logger looked the same.
On the 518 a change this big would have been very noticable.
I very rarely understand any of the drivel that Irgo writes... but in this case he almost seems to be correct. The Boost Start isn't doing very much that I can feel or measure.
Next week I'll try turning all of the boost off and running 60 "degrees" of turbo with no delay and a soft turbo ramp. If the problem is that the boost is coming in too early, this should bring the bottom-end back that the 119 is missing.

I don't mean to sound disrespectful, but what standard of "heat" are you winning?
I'm not looking for heat wins, I'm generally looking to TQ club meetings, and generally looking for A-final placings in regional level meetings.
With 20-odd years experience at the sticks I believe I have a pretty good feel for a cars powerband.
From that basis, I have found 119 a significant disappointment compared to 518. 518 came with a very clear initial setup for 13.5 which I used and was extremely happy with. 119 came with a very vague initial setup (boost anywhere between 30 and 50, ratio anywhere between 5:1 and 7:1 etc.). I went for something more or less in the middle of these very wide ranges and found that the top end was perhaps better than on 518, but the bottom end and general throttle feel was a lot worse.
To read irgo's comments - and although irgo's posts have flaws, I do believe that he takes his measurements seriously - and add it in to a number of other comments on this thread, and what I have heard from people trackside, perhaps there really is a problem with the way 119 applies the boost?
Cherry - I'm afraid that as the UK importer, your comments will be interpreted as representing the product, even if you do not intend it.
Again, the overall impression I get is that this software has been rushed to the market without the same degree of testing that was put into 518. Three alternative versions released to the public (one officially) with a month is too many. A basic setup with such a wide range is virtually useless.
Anyway, I will quite happily go back to 518 for now as it was working well for me (although I personally will be looking to run in zero-timing classes over the summer). I have no problems with the Hobbywing hardware - it is good quality and represents excellent value - but feel that this software release has been handled badly.

Can you re run the test using 518 just so we have comparison data to work with, I love this side of the ESC's we finally are able to become proper geeks with our speedo's can't wait for the comparisons, may even consider buying a data logger just for the crack of it lol.
