From a business perspective ,IE- making money,I find it strange that Tekin don't charge you at least something for the software updates.....

For example, say $20 U.S . Much cheaper than a new esc, whereas LRP make the $ for a new speedy, but probably lose lots of customers this way.

Sony do a similar thing with their PS3 store,sell you a game,then offer extras and add-ons ,as they are produced at a much cheaper price.

Free updates may make you lots of friends,but not neccessarily keep you in business.

You have to be progressive. The first lot of BL motors didn't even have timing on the can. When they brought out timing on the can I didn't hear anyone complain, they just bought a new motor.

If you want something that will bring it back to a real drivers class have a handout spec motor and speedie combo and the big race meets, it just has to be fast and affordable.

What you can't do it limit every one to a brand of motor or speedie for a year, what will happen to the sponsors.

I had a year away from racing last year and the summernats was my first race in ages, last time I ran Stock, it was with brushed and it is heaps quicker now. Lipo and adjustabilty in the speedies and motors has made it quick. I have an Tekin RS and it has made it easier to be fast but you still need to setup the car and drive it.
I remember when mod was a 10T brushed motor with 1800mh cells in a TA01, times change and you need to go with it. 17.5 is faster now than that these days, but so was the Brushed stock cars with 4600mh NiMh batteries.

I am sure that Stock used to be a chrome can motor back in the day. Stock didn't mean "Stock" 5 years ago.

As for there not being a nice step between classes, change Stock to 17.5, ditch the 540 class make it 21.5. And before anyone complains about not having a 540 class, When it was all brushed, I raced 540 and Stock at the pointy end for a whole CC. The difference in speeds between 540 and Stock was less than a second and with the money spent on new motors for 540, it would have been cheaper to buy a 21.5 BL system. The main problem it that everything has gotten quicker but 540 is about as fast as it can get therefore making a gap between 540 and Stock

Classes should be
Novice (540 chrome can)
21.5
17.5
10.5
Open

Gee................thats the most I have typed in ages :D

Every sport develops

Develop with it or be left behind

Calaway bring out a new bigbrertha
every year it compation that keeps
all industries alive

And its healty

540 is ment to be the class for running
the same motors at entry level

And at clubs that's how it is but if you step
up to cc level motors are cranked zapped
and tuned so I guy only starting out can't
compete anyway but it's all about the learning
curve

thats y the rpm limit was imposed. However a used motor that had never been tweaked, Only regular cleaning,oiling and com drops pulled above that limit when tested.

Back in the brushed days the novak GTX? was the speedy to have you could not get close with a budget speedy. I ran 540 with a $50 speedy, then some of the other guys i enjoyed close racing with bought higher end stuff and i struggled to keep up. Its the way of this hobby and has been for years, just moreso now that new tech comes out fairly reg and to be up the pointy end u have to update. Remember brushless tech in rc is still young there will be a point where they wont be able to go any further with AT tech then they will search for other areas to get more out

I bought a Tekin RS Pro to guarantee run time at the Nats in 1/12 with a 3.5turn. The feature I was most interested in was the Current Limiter in dual mode which ended up working better than the driver.
When I run 10.5(origional Losi) and I play with the Tekins settings it goes nuts. I can only imagine what it is like on 7.4v

I have got the RS-Pro $199 , SPX Stock spec.$210. LRP SXX TC spec $189 aus (not used yet) Thats what I paid for them..
Ran both in 10.5 and 17.5....
In my opinion...The LRP wins hands down as it has Brakes/push a button and the settings change...No exsposed pos and neg bars..I shorted the first one i had..it lasted 25 mins.. (Tekin has awsome backup service, told my story and they replaced it at cost..I would of had the first RS in Aus at the time) Has no reverse polarity protection...Im not sure if the LRP does. Novak does. Dont really want to find out either :)...I tried everything to get brakes with the Rs and I gave up....some say they have plenty..but the lrp still out brakes ANY RS speedy...The LRP has loads of brakes..
The RS has ok slow speed brakes..but the faster you go,,the less you have...The Fast stock guy admited he had no brakes...and I dont reall want to carry around a computer...more stuff to pack..and who wants to be a rocket scientest to play with our cars..isnt there enough going on with that???
My son runs 17.5..SPX Stock ..profile 7..An Orion series 2..(got rid of the Redline,,crappy motors), he wasnt slow either..Wait till a Duo 2 goes in..
But it is a bit silly..stock aint stock..but dont we have novice for that reason?

One thing that Ide like to know...The tracks in the USA all seem to be short, indoor carpet tracks...Ask a question,,(tyring to get brakes from the RS) and explain the track size,,and they, well, how should i say this...Go and buy a another gallon coke to calm down...:smile: And they always say the have plenty of brakes
I use an RS in my 1/12.who needs brakes in a 1/12 any way. Tried the vegas software @67mmm roll out 1cell lipo..its quick....motors cool.

heres a link to a in car 1/12 cam..u can here the speedy wind up..If you look at the other link..listen how the 10.5 LRP goes into "turbo"..i think ill take a gear off ang get it earlier..so much easyier than carrying around a computer..

http://www.youtube.com/watch?v=3iux8m9hlqU....1/12 link

http://www.youtube.com/watch?v=3iux8m9hlqU


..Going to put in the new LRP SXX TC spec and see...
The guy that dominates 17.5 here, runs and "old" SPX with an old duo...It died on the weekend..finally:lol::lol: the motor that is..Thats to you Ben....

But guys...seriously...With the dollar high...a new speedy costs around $200-250 Aus....I remmember when a speedy was $400 plus.....And racing, exspecially if you want to be at the pointy end..is not cheap anyway...
How much do we spend.."chasing" motors/ batteries/tyres?
The way I see people throw tyres on their cars..well a new upgraded esc aint that bad,,
My 2 cents worth anyway..
Mike

Hi Mike love ya work mate but............

I was there at the last meeting and Scott was quicker with the 17.5 Tekin than the 10.5's

No-one kept up with the RS 203 software.

For BL speedies.. Has anyone noted how much current difference the various speedies are drawing in 5 minutes. And does anyone know if it's skipping a pulse and punching the next in the turbo modes or simply advancing the timing, shortening the pulse and packing more current.

I cant seem to get my head around how we've managed to get to 5 minutes and no ones bringing up the subject of having 5.6A of juice on board using a lightweight LiPo. As much as it's silly to think we can go back to NiMH, the fact that batteries should be removed from the weight rules bewilders me.

PS:... Gonna go and put the washing on with my 10 year old brushless KIWI washing machine!

Speed Passions new speedy from i have heard in testing stages it adds a new level to LRP's Turbo timing and with this speedy if there is updates you dont need to pay for the update you download it free from there website. This speedy will be one to watch out for.

So, attempting to get this discussion back on track....which way do I jump? And where is the best place to purchase? Like i said earlier, I'm happy to buy local, but I won't pay a huge premium over o/s prices.

Decisions..

I did not start this thread to "have a whinge" as was so expertly suggested earlier. I was looking to see if the ESC's were a contributor to the difference in speed in what should be a 'spec' class.
I am in the market for a new esc anyway, as my GTB is a borrowed one after i flamed my second one a couple of months ago.... So this was to be a means for me to determine which way to jump. My thoughts as follows;

-Being able to make changes/adjustments at the track easily a definite necessity. Can do with a computer, but would naturally be easier at the track if this not strictly required.

-Should have the 'active' timing adjustment, so at least I can have the power to keep up. It then be up to me to drive well enough to take advantage of it.

-Should definitely be software/firmware upgradeable. Don't see the sense in buying a new esc every year!

-More than happy to buy local, but not if the local price is double the O/S price, as is often seen with LRP and Novak.

-Suggestions where to get these from, local or o/s?
-

Ok.. good point...

Make up your own mind when you want to spend the $$$ or whether you prefer to hop up at an affordable level and wait for the top end gear to get cheaper. You'll be buying speedies whether you like it or not if you want to be at the pointy end. Where you buy from is up to you...

Some good reading here guys and lots of valid points.
Unfortunately for the stock classes to become an even field requires all drivers to run the same equipment etc.. which I dont see happening here. RC racing is just that... and like drivers manufacturers will always try to out do each other with faster products as what was mentioned here already, consumers nightmare, retailers dream (true way to put it) and we still buy, not only to be able to be at the pointy end but to push the boundaries of what these cars and classes are capable of, and the technology..its intriguing how far they can go, its one of the reasons Im still racing as it never gets boring and always a challenge.
Im quite enjoying the current speed of 10.5 and it will only get quicker as its now become a smaller step to mod, hell at some tracks were just as quick.
The last jump in speed came from weight reduction...ok so 75g isnt much but weather its wight esc's, motors or lipos something quicker is always around the corner.
I do believe though nothing of the above will help unless your super consistent as 1 fast lap doesnt get you a decent place on the grid nor wins races, if anything a slower car could be faster for you to first gain that consistency.

For those deciding on what speedie to get or want an upgrade...I'll rephrase that...need an upgrade and arent sure what to get, find out what the fast guys are running at your track, these guys can also help and assist you with setups as well.

I run a GTB in stock atm, it might pay for you to do what i'm going to do......wait:nod: I'm going to see what comes out in the next few months and how they all stack up against one another. Brands wise, i have no allegiance, but what i would like is freedom of choice, i just want there to be a good selection of speedies to choose from. A bit of healthy competition amongst manufacturers would be good.

In regards to the parity of stock and the ability to adjust timing and so forth, the only ones to blame for the current "state" of the class are the governing bodies who approve these electronics for racing (ROAR for example). If electrics are going to give "unfair" advantages then why put them on the list? Pandoras box is open now, cant say "sorry, the thousands of dollars worth of speedies everyone has bought are now no good to use in that class". More drivers would be lost than won over, and if a spec speedie is introduced then possibly 100's of racers around the country would have to buy a new one. I'm not going to buy a new one because i have to, but because i choose to.

I just tested the new RS 203 software out today with 17/5 and got it sorted,

It is a lot quicker than what Scotties car was the previous meeting, I'm talking 10.5 speeds and I also had to drop the brakes back from 100% to 90% as they were too strong and locking the wheels up at the end of the straight.

Mark, Anthony and Lou were there and were amazed at the speed from a 17.5 :D
