It isn't the Tekin motors that gives them the higher top-speed. I don't own a Tekin motor - I race with a Speed Passion V3, and still experience higher top speeds than Hobbywing users. BUT... It's not a lot.

It sounds more to me like you are talking about the differances between sensor Vs sensorless and not fixed timing (like the timing being applied by the sensorposition on the endbell) and dynamic timing(wich amount being applied is depending on the actual rpm of the motor.

It just seems smarter to me like others are trying to say to minimising the static endbell timing and adding it in a more controlled manner dynamicly.
And for higher wind motors this means that more dynamic timing has to be avalible!
(Remember i am talkin true zero enbell timing and not the "zero" marked on most motors!"

That way you can choose when to apply the timing with the use of the speedcontrollers dynamic timing settings. Wich in turn should help the motor to run more efficient and cooler.

I take it for VERY unlikely that Tekin would have passed ROAR classification if their motors were Deltawound...

I think it is more likely that they have more static timing built in.

yes you can .same unit.

Yeah, sorry to beat a dead horse here, but I was strictly speaking about ESC's. I've tested both back-to-back with the same motor (typically a DUO2 or SPv3) and while the HW feels like it has more rip out of the turns, and it's certainly easier to drive, it produces slower lap times. Clearly nobody else thinks there's a problem, so I'll just leave it at that. Thanks for the replies everybody.

too fast or too slow or not enough timing or recording slow lap times or running too cold or hot or no top end ...

I was reading this toppic.
it is quit intresting to read the reactions about the HW vs Tekin.
first I want to say that I never drove against a HW or drove with so I don't say that one of the 2 is faster or better.
still the driver is the one that wins and not the speedo.
the small differences between the speedo doesn't make you the winner.

than advanced timing.
I have it now about the Tekin and how it works.
the timing comes in ad a rpm that you can choose.
the timing reaches his max ad the end rpm that is choosen
example.
start rpm 1000
end rpm 11000
timing set on 50
than you get a window of 10000 rpm.
every 1000 rpm there is 5 degrease of timing added.

now every body is talking that more timing creats more head. this is right but because of the advanced timing, this is lowerd so there can more timing added to the motor.
a motor can handle more timing as it runs ad a higher rpm. so the higher rpm the more timing can be added to the motor. this makes it posible that you can reach a higher top speed.
as the car drives away, than it needs power. the power is the highest with the timing on 0. (talking about the speedo timing and going out from a motor with pre set timing)
by a narrower window you get a higher accelaration.
as you use the first meters with 0 timing on the speedo, you get the best acceleration and you can gear it heavier.

than the motor.
it is nice to see the Kv ratings but this is not the reason why the Tekin motor is faster.
it depends on the timing on the motor.
all motors with the same timing on the motor will give close Kv ratings.
there is only one thing that is different with the motors and that is there sweet point of timing and gearing.
some motors like more timing wile other motors like a heavier gearing and less timing.
each motor want his own gearing and timing.

advanced timing is deffenetly keeping the motor cooler when setup right.

No!

ROAR don't mess around with essential things like connecting a motor Wye(star) or Delta.

I think iv'e heard someware that a Delta connection makes the squareroot of Pi or 1.77 times more power than Wye or something along those lines...

It is very easy to get a high Kv by adding more endbell timing but torque suffers.
That is also why it could be a really good idea to have more timing avalible in software!

IMO Numbers on a page dont mean crap as I have not raced against a fast tekin motor yet and i think the much loved SPV3 is average against the Mighty Duo2 Regardless of brand speedy A better driver knows set up and knows that with a slower more consistent car he is always going to beat a hack in an straight line missile

The only difference at our club between the HW and Tekin users is driving ability as most of the experienced guys are running about the same speed just different consistency.

snabbgas

Yeah, but this thread is all about the Hobbywing Stock firmware and its
development towards being better and faster and not
about car setup or how to be a better driver...

As such all this talk about timing, dynamic or static or whatever is highly relevant!

And i think "numbers on a page" would mean quite alot to you if you were racing
Hobbywing against boosted Tekins in the days prior to Hobbywings Stock firmware

millbank

make sure the motor is set at -10 degree timing

I just got a new xerun 120A esc. I also ordered a cap for it because I didn't realize that one was included with it. The one included has 2 caps, and the extra I ordered has 4. Should I leave the 2 cap on there, replace it with the 4 cap, or can I run them both? Thanks.

Hi guys

Nice information and interesting but most of you have fogotten one important factor and thatis driver ability .

No matter how much timing a company may it be tekin ,hobbywing,lrp ,castle creations or whoever puts into there esc's and motors it doesnt mean your going to win the race correct? It will not give you any advantage over the pro guy or the veteran club guy .The pro guy would still win by 2 laps even using a cheaper esc lower end esc as he has many years of experience as a driver and that goes with the veteran club guy .

I could attach two motors and two esc's and 2 batterys to a car and give it to any of you with not that much experience and you will still not win .Probably not finsh the race as the reliablity is gone .

It's all about the ability of the driver and not the horse power behind the car .

the other things is marc rhiehard won the world title using a Hobbywing designed and manufactured speed passion GT series using designed and implemented software the same your using today on you sp's and hobbywings but what won him the race was his setup and his ability as a driver and not the horse power available on demand .

ok the end of that .

Hobbywing is looking at ways that they can improve there products in ways of hardware and software but to the extent of the product being reliable .

Ill kepp all you guys imformed
