ESC: Which one to buy...
 

I'm juts getting into the 1/10 scale Touring cars... I'm going to start off slow starting with 21.5 and working my way faster.... But I dont want want to buy a new esc every time, I want to buy ONE good esc and be done with that... If it makes any difference im going to be running an Xray EU rubber car...

These are the 5 im looking at:

Kopropo VSF-1 BMC

Speed Passion GT2.0

LRP SPX

LRP SXX

Tekin RS pro(no motor limit)

Are all of these sensored? I also want one thats easy programmable through my pc even if i have to buy extra equipment...

Also if someone could shed some light on this question it'd be great. On LRP ESC'S whats the difference between the TC spec and the COmpetition spec?

Thanks,
Alex

for stock racing i will definately say the Tekin RS or Pro.
The performance is so noticeably better and faster than the SP GT LPF i have.
The online service and support has been exceptional as well.
Big plus is that they are developing the software continuosly so no buying a new esc but update the firmware/software.
Yes its a schlep taking my laptop to the track compared to the hand held programmer from Speedpassion.
The inconvenience has been so well worth it :)

sxx esc, its new, its a lrp, it will be good.

+1:)

he listed the Speedpassion GT 2.0 not the LPF.

The only ESC on the list i have tried is the SP 2.0 with the 2.0 and a 6.5 in mod i have no problem running with the 4.5 /tekin/novak/lrp powered guys. the 2.0 is programable with a lap top for software upgrades as well as other tuning options with the hand held programmer included with the esc


All of the ESCs you listed are sensored, the SP when paired with a SP motor can be run unsensored.

I'M sure you will be happy with anything on that list.

I love the SPX! Its easy to program. Yes, its sensored. Works brushed or brushless and w/ any battery out now. 7 different profiles for you to increase as you get better driving. Even set to give you an awesome start with a programed "hole shot" just by holding the brakes while at the starting line.
I've used it w/ 17.5 and 21.5 and NiMh and Lipo. Worth the money. No extra program cards to keep track of either. Two button two led programming. Even keep track of its own temps.

I really like the tekin stuff I really like the hotwire but I was told the KO vsf-1 is THE BEST esc on the market to date... I want software to use on my lap to program my esc...

Alex

Depending on how much time you want to spend programming and setting up you ESC, here are my picks in order of easiest to most complicated to setup for good speed.

LRP SPX - quick and easy settings (pre-installed programming works best for 10.5T+ motors)
Tekin RS - adjustable via hotwire, fast, reliable, good support (5T+ motors)
Tekin RS Pro - Same as above - no motor limit
KO BMC VFS-1 - very adjustable - good support - (+4.5T w/o heatsink & fan)

The LRP SXX is a good unit too, just not best for stock racing against the current crop of ESC's, as this unit is more suited to fine tune the power delivery of modifed motors, though it can also be used for stock, it will be down on overall top speed.

On another note, the Tekin's have the smallest footprint, the KO and LRP are roughly the same size, but the KO is the heaviest between the three.

As for the Tekin RS Pro, there is no need to opt for the Pro model unless you have plans to run modified motors below 5T. From your statements about starting with a 21.5, it sounds like you will be gunning for stock to superstock motors. BTW, I would not even get a 21.5, get a 17.5 motor and just limit the max throttle on the transmitter to shave some power and speed. No Point in wasting $80 for a motor you will QUICKLY outgrow.

+2 Tekin RS

No need to buy a new speed controller with the free software upgrades. I switched to all Tekins from Speed Passions. Never go back. Great support.

As for motor go with a 17.5 for TC. 21.5 is mostly run for oval and vintage.

As the others have said get a 17.5 instead of a 21.5. 17.5 is fairly easy to handle but has more then enough speed (when geared correctly) but slow enough that you shouldn't have many problems keeping the car under control. Plus Stock Tourer is 17.5 (27t brushed) with a 21.5 you probably won't be keep up too well.

I'm currently using a LRP Sphere TC spec, it's a great speedy. If/When I would get another speedy I personnally would go for a LRP SPX. I'm biased towards LRP, but I heard lots of good things about Tekin.

+3 RS pro,smaller,no need heatsin or fan and more power if have howire,Great support.....thanks ! tekin...

+3 RS pro,smaller,no need heatsin or fan and more power if have hotwire,Great support.....thanks ! tekin...

OK so ive done some talking and no one can tell me mabe you guys will know...

Will the tekin advance the timing once you hit full throttle... Kinda like a boost? i knwo the ko propo and the lrp's do but no one knows if the tekin does...

Alex

Not only can it do that, you can adjust the level with the Hotwire. AND, soon they are releasing new software thst has Turbo, which will fire up only when you are getting up in the revs to obliterate those long straights :)
+ whatever we are up to, for RS or RS Pro :)

The one down side to the Tekin RS is that once you have it, you won't run another ESC. So you end up buying them for all your cars. I'm looking to buy a third one ATM.

--pakk

So it looks like the tekin rs pro + hotwire is the way to go...

Now will the tekin run with anyones motors? like lrp, or speed passion motor? or should i just buy the tekin rs pro combo?

I know novak esc's DO NOT like using other manufacturers motors...

So no one can tell me much about that ko propo unit... looks like the tekin is the way to go...

Why is the ESC w/ no motor limit $40 more expensive than one with no motor limit? if i buy the one with a 5T motor limit can it be changed over to the one w/ no motor limit?


Alex

The RS Pro has an extra PC Board with an extra layer of FETs? to handle the extra power. It is about 1/4" taller than the RS.

I have both the RS and the RS Pro. I think the RS is all that most people need unless you really want to run a superfast mod motor. Where I live, it is difficult to find anyone racing anything but stock motors (17.5).

Andy

OK thanks for that info... Ill just go with the rs I suppose... I wont be going below 10.5 I dont think ever....

Alex

You can run any motor. sensor or sensored. I have ran Trinity duo's, novak's, and orion excelerons on both my rs and pro. I also noticed no difference between the rs and pro, not even temp. With 17.5 I don't ever see more than 1 led light up indicating the temp.

Why is the pro $40 more? Because technically speaking it is better. It has lower internal resistance, it should run cooler, and it handles lower turn motors. But as said, save the $40 and use it to buy your hot wire. It is a must, IMO.

And if you have not looked already, go to the Tekin rs thread. You will see their support shine in that thread.

and...one more thing. Something I learned in that thread is that Tekin sends guys out to the big races to "help" with that they can. Randy was at the reedy race and he is at the norther cal off road champs as we speak.

what more could you ask for?

--pakk

Im thinking about buying the RS/17.5 or 13.5 como... I kinda need a car to put it in first...


you guys thin the JR DS 8711 is too much servo for a xray touring car? I baught it for my 8T-E but im selling it to get a touring car..

Alex

That's an offroad servo. You don't want that. Get a futaba s9551. It is my personal favorite.

You need a car too? You got a budget? What else you need?

--pakk

I need everything but lipos, charger, balancer, and rx/tx lol

I was trying to sell off the 8T before i started on the TC... Less than $1000 lol

Alex

Ok this is what you want.

Photon

Tekin Rs combo


Hotwire

s9551

r9-r (I don't like mazdas)

SJ-R-36

Did I forget anything?

--pakk

Im running indoor carpet on rubber.... Im looking at either a Xray T2R or the AE TC5R...

this tekin system: http://cgi.ebay.com/Tekin-TEKTT2151-...3286.m20.l1116



Alex

Usually i dont buy car kits if my hobby shop doesnt carry parts there... Know what i mean? Not to throw out your advice or anything...

Alex

this is my #1 choice so far... http://www.nexusracing.com/product_i...oducts_id=2443

Alex

You are 100% there. I try to buy from my LHS as much as I can. My LHS happens to carry all of that except for the servo. I forget the part number, but KO makes a low profile servo very similar to the one you listed but closer to the futaba. It is just a lot more expensive. The KO you listed should do fine, but I can't comment from experience on that one. The KO I do have, runs great.

--pakk

Theres a few guys at the track running these ko's and absolutely love them... they say its the best servo out for the money...

I may run the DNA body IDK yet...

Alex

Hi Guys,
I'm thinking of picking a new speedo myself, one that can advance the timing on the straights. I like what everyone says about the Tekin, but I keep seeing threads here and there where people complain about weak brakes. Can anyone shed some light on this? Does it only happen with a particular motor? Is Tekin addressing this? The RS looks mighty tempting right now. :nod:

Thanks,
JV

I havent read much about the weak brakes.. can you post a link as to where you read that?

Alex

Just go to the Tekin RS thread and do a search on "weak brakes".

As you run a Tekin Redline motor you have no weak brakes.
The Speedpassion motor is braking not good but that is the slowest motor I got.
The Tekin and the LRP motor's brake good.
My best motor is the Tekin Redline.
That is incredible fast.

thanks for the info mkky32... I will most likely once I get things purchased be running all redline motors...

Alex

You will love it.
I have the Turbo already on my speedo.
I drive with a Tekin Redline motor 10,5T on 5 cell. It's just incredible fast.
Gear it light. very light. Infield is great and very good top speed.

"Gear it light." meaning gear it high or low?

Alex

I gear my car about 6,4 to 6,9 FDR
All other drivers use a 4,5 to 5,4 FDR.
LRP motor about 6 FDR and speedpassion about 5,4 FDR

That's the different.
It's quit big but the Turbo helps to go faster.

I tried it today on the big track and I can tell you that Tekin is with the 199 software the nr 1 on all tracks.
With a Tekin motor it's the best combo there is.

Thanks for all the help mikky!!!

Alex

what about KO BMC (or Orion version)? people said this speedo is very fast. especially with the adjustable frequency tuning option. at my home track, it is really fast (mod class), compared to LRP sphere and speedpassion GT2.
(fyi, in my country no hobbyshop sell Tekin)
i think its variable frequency tuning option is very good for stock motor.

anybody think the new orion racing esc is good

So I found a T2'008 EU for a good price!!
