tekin r1mt
 

tekin finally posted a video of there r1mt esc in an e-maxx. doesn't list the motor or number of cells though. Atleast it shows that one exist though.
http://www.teamtekin.com/video.html now which ever one comes out first, the MMM or this I will pick up.

That could be anything in that E-Maxx. Just pickin on ya. I bet the MMM is out first. :005:

probably but at this point i will just get what ever one is out first.

That could mean a couple things, either the production comes out first, or the betas come out first.

I think that Tekin's ESC will be out first. If you only remembered how long the wait for the MM was...

Oh believe me I remember. I still think the production MMM will be out first IMHO.

Id really like to see a picture of what the Tekin MT will look like. The no heat sink thing on the R1 kinda has me a little worried about them. Is the R1-pro out yet? Its supposed to do 5s.

the r1 pro was listed at 5s put according to tekins website its only listed at 3s or 12 cell nimh now. http://www.teamtekin.com/r1.html

The Tekin add in last months RCCA still listed it at 5s. See even they know that 5s with no heatsink is stupid.

It seems the old features of the R1 Pro has been passed down to the MT version.
It makes more sense now.

Whichever esc comes out, I'll never care.

They've deeply failed me.:019:

I've spent three years of ma own life dreaming of the MMM that would do 6-10s lipos with ultra hi current.
And Tekin is only copying the CC car escs.

Gimme a break.....:030:

Guys.... word on the street if you haven't heard before.... let's just say that Castle is "involved" in the Tekin products. ;)

I'm expecting to see some very curious similarities between the Tekin and CC stuff.

I have been blasted on another forum for suggesting this by a Tekin zealot, but I believe that more or less, Castle is building Tekin's stuff. Castle won't admit this if you ask... but they do give the classic "I can neither confirm nor deny" which pretty much means it's true like 90% of the time? :D

I also believe this a big reason behind the delays the past few months from CC.. for the MM updates etc and the MMM... they are busy building twins. And maybe they are feeling the heat of Tekin to get their's done? hee hee who knows...

This is not to say the products will actually be the same or look the same... but I expect the basic foundation will be the same unit.

The Tekin has it's own unique features and programming ,etc for sure...

Then again, maybe I've been misled completely and there are no ties between these companies. ;)

Looks pretty good to me.

There's a very high possibilty that you're saying the truth. Quite funny, though. The real FOOL is going to be none other than the customer, if what you are saying is right.

I do however find it hard to believe that castle would design a controller without a heatsink.
I find it more likely that castle has licensed there technology to tekin for them to use in there products.

If the ESC is made with enough FETs, the resistance is lowered and power dissipation will be lowered as well resulting in less heat. Also, there seems to be some evidence that Castles has quite low pulse rise time, further lowering heat dissipation. If done right, a heatsink shouldn't be required, although I'd still put one on there for peace of mind. Plus, you KNOW people will be pushing the ESCs beyond their intended uses...

Castle makes lots of escs without heatsinks... just not for cars. ;)

I doubt Castle is building the whole esc... but I can easily believe they are making the heart of it, and incorporating the design elements that Tekin wants.

In that case... their products are different... but still "siblings"

Look at the M25 and Tekin Rage... the first Tekins even had green motors! (with a tekin sticker of course) And from a distance (I don't have them to compare) it looks like the Rage could well be a hardcased M25 with a big cap inside. Anyone had them apart??

Careful with what you say guys! TeamTekin has joined the forums.. :p

i don't care who makes the controllers, as long as there is service behind them, you can't go wrong.


(muppets Statler & Waldorf style;)

Rumor has it, that schulze service department has been sold..

WHAT DEPARTMENT?!

The Emaxx in the video actually had an R1pro, 4slipo, stock gearing and a 2kv 36mm long can motor. The R1mt will be a beafed version to handle 30 min mains or continuous running. Honestly the R1pro looked like it was going to handling it, without a heat sink. We blew up the motor before the speedo got close to thermal.

All of our speedos will actually work on 5slipo. We rated the R1 and R1pro for 3slipo so we do not have to explain that you cannot use the BEC on higher voltage. With the MT version we intend to offer a seperate BEC module. Groups like this will figure it out. The rest of the world is happy with 3slipo since that is plenty for the vehicles these are really designed for.

I assure you we design our own products. We might peak at the competition to see what they know that we don't. CC does make a fine circuit, but not as good as ours. Tekin has been in this biz for a very long time and has a very nice patent portfolio. Our key employees are engineers, as am I.

No need to be careful. It is your forum and what they are for. We are just visiting and have no problem with earning your support.

I'm very glad to see you've dropped a bit more information on us about the R1MT. Now, how about MSRP of the R1MT and an ETA?

Great! now combine that with a nice price, and a good service, and you have got a killer combination in hands.

Thanks for posting.

I was right on the 4S thing then..

the 36mm long motor is considered small for an e-maxx. (most likely a non segmented one?) a longer can would most likely have survived better, since on 4S, the 2000Kv is a good choice. But for a smaller motor, a higher KV would have been wise.. (apparently you took it beyond its most efficient level and smoked it.)

I like your 30 mins point of view.

thanks for giving us some info. I actually signed up on tekins site last night to get some info after I saw the video. Can you give us any ETA on the r1mt? or rough estimate on price for the esc or as a kit?
thanks

If your products really are 100% exclusive to Tekin that's cool... good news!

I'm still skeptical.... ;)

I could understand, perhaps the design is 100% Tekin but the mfg is outsourced ...? I have wondered if maybe that is the deal.

I've had Tekin stuff for many years. I actually know where the real roots of Tekin are.

The company started about 5 miles from where I grew up, out in the rurals of Iowa. It started as part of Delta Mfg which still is there in a little shop in the middle of nowhere. I have a couple Tekin chargers that need a little check-up someday. 112a and 112b.. and an old 110 and 111? (the black one)

How long is the "long can" motor?

Serum I don't think he meatn it was 36mm long.... he meant it's a long can 36mm motor. :)

The 5s sounds great.... and is rather peculiar lol....

Considering how well the R1pro handled the load it may be sooner than we thought. This was our first heavy load test and even we were impressed. Let us digest what we have learned and we will let you know.

Our goal is to meet the needs with 4s or 5s max. Beyond that we are forced to different fets and we really like the ones we have. Do you see any other speedos with no heat sink running even mild motors?

If we just have to heat sink the R1pro it will not be much more expensive and not take very long. The controller already has crazy high amp ratings as long as the heat is controlled.

We knew the motor would not handle it, but we really like breaking stuff. Thats are job, break it..make it better.. break it.. make it better.

5s is not unique to anyone. We all use fets rated to 30V and need head room for voltage spikes. Higher voltage fets do not perform as well.

Motor was 54mm long, 6pole 18 wind, 2 turn. A proto we are working on for 1/8 scale.

Mike is on the short list for testing, so you will get direct info.

Tekin Prez

Considering my posts of the rumors.... I'm just messing with you, ha ha.

So far things sound awesome. I hope these FETs are that good.... but whatever you end up with, a small heatsink added for good measure won't bother anyone running a 1/8 setup like we do.

1/10 buggy is a different story of course....

Sweet! I'm glad to see a good ESC that can handle 4 polers is comming out. What kinda price though?

I think this covers it Squee;

'If we just have to heat sink the R1pro it will not be much more expensive and not take very long. The controller already has crazy high amp ratings as long as the heat is controlled.'

I take it Mike is going to stock the R1MT then?

Is the FET board going to be single sided? This would make it much easier heatsinking things.

That would make it huge and inefficient. The pcb has more resistance than the fets. We have truly reached the point of diminishing returns of fet Rds on. Part of the of the magic is that we use 2 boards, half the current in each one. Shhhh Super heavy copper, multi layer, designed to reduce all trace lengths.

R1 has 24 fets, R1 rpo has 48 fets. We thought the Mt would need even more, but these fets are proving to be pretty amazing. It also helps to have the high voltages. Voltage is our friend and current is a beotch. Power =VI and more V reduces the I for a given power level.

Also our solder post make really good heatsinks because they are soldered to the power planes. It is basically a copper block and we can pull the heat from anywhere. We will likely flip it over and heatsink it on top just to make sure we have lots of head room. It really is a big block of copper and we can pull heat from the entire mass.

If we could keep the fets at the 25C ,where the spec numbers are rated at, it would push a real car. Spec sheets can be very deceiving unless you read between the lines and account for actual conditions. Truth is the fets are over 300F when the units are close to thermal and perform no where near their ratings.

If we impress Mike we are certainly hoping he will carry our products. We like to earn it.

Tekin Prez

Great info, Jim. I wish we had you here a long time ago. :)

You don't happen to be any relation to the Ken at Delta??? I was pretty sure the name is just a coincidence since the orginal Tekin guy was not a Campbell anyway.

Just a heads up for anyone . . . the Tekin guys come to our local track to do testing and I've talked with them about some of their setups. Back when they were doing the 1/10 systems I had my Lightning Stadium 10 with the Mamba Max setup. We talked about the brushless scene and they were very helpful and seemed very dedicated to a premium product. Well, basically what you're seeing from their representation now.

Good guys, good product. The locals here in Boise rant about them. I'm looking forward to seeing their esc so I can pull my MM from my brushless CRT. :027:

Just thought you guys might like some first hand background on them. For whatever that's worth to you.

I think it's nice that he came to this forum without even having a product represented in Mike's store. With so much hype put on the future MMM, I think the R1MT could very well be a hot seller if it comes out first.

Looks like i might have to get a couple, I have had a tekin rebel since before the troubles tekin had and it refuses to die, its close to 10 years old and sitting in a box, but i know if i hook it up to a battery it will work and work hard, no questions asked

I'll jump on Tekin's bandwagon too if they deliver the goods.

Prez, can you give us a little more specific timeline... like a best-case early date and a work-the-kinks-out date? Are we talking end of the year? A month or two?

If you get this out before the MMM.... that's a big shot across CC's bow... you stand to sell a lot of units immediately... guys who have been waiting to grab a MMM.

I could actually give up computer programming if tekin keeps its programming setup, I'm even thinking about the R1 Pro for right now

Nope. I have heard there was actually a Jim Campbell at Delta as well.

Sower - I hear they redid the track with fresh dirt. Looking forward to coming down and turning some laps. Maybe we will set up a demo day and bring a bunch of product that everyone can try out. We are almost ready to start building our track up here and get outside and then it snowed! We have burned a pretty good line into our new carpet track up here already. Stop by anytime and check it out.

Glass doctor - I have learned my lesson on announcing early. I expect it will only be a few months. However we need to really understand the application a little better. That vid is a pretty good start and builds my confidence. Really shows just how big a load TC mod car on foams really is since that is our test baseline thus far.

At the very least injection the molds for the housing can be 6 to 8 weeks even if you have friends. Our molds are built locally so that helps with timing... as long as I buy the beer.

Tekin Prez

Nice. Thanks for the invite. The next time I'm in the area, I'll see if I can stop by. And yeah, the track has new dirt, but no layout yet. Hope to see you at the track soon with a nice 1/8 scale brushless to run with my Jammin CRT/Lehner. :027:

Keep us posted, and thanks for the info.

thanks for the info. looks like I might have to pick up another mamba or the r1 pro to hold me over until the r1mt is released.

Cool I'd bring the beer too... but then how much work do they get done? :D

NOW we know the true source of the delays, lol....

its called testing, in the boardroom:005:
