tekin r1mt

[glassdoctor]

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.

here is the quote from the president of tekin. he says it will do 5s if you disable the bec. that is what i want to try in my 8ight. the mm is doing well but is being pushed past its limits.

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?

[Serum]

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.

[gixxer]

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)

[glassdoctor]

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....

[teamtekin]

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.

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....

[squeeforever]

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

[Serum]

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.'

[zeropointbug]

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.
