Team Tekin R1 Pro brushless speed controller

[captain harlock]

One other thing is that the Tekin president is fighting with tooth and nail with ROAR to make the Tekin brushless systems Roar legal. Not to mention that these systems are SENSORLESS.

That's the trouble with many electronics manufacturers, the get creative with the numbers and you're never sure what "headroom" or safety margin was designed into the product.

That's why we "test" the limits! LOL, unfortunately, it costs us money to do this at times. 4s would sound more fesible for this esc.

Well, there's still a chance for Tekin to make it a reality.
Jim, the president of Team Tekin said that it's smoother than the Mamba Max with no cogging at all. The system also has a glitch filter to make sure the radio signals are being sent with no interference.

I would like to see some testing on this esc...

[captain harlock]

Me too!
Though some people were given these controllers as beta and they really liked it.

Its gonna be two types of controllers with different KV motors.

The R1 will accept from 1 to 6 sub c cells and 2s lipos.

The R1 Pro will accept from 1 to 14 sub c cells and 5s lipos.

If the Monster Max will be out in the near future, I'm sure Tekin will release a more powerful controller for the monster trucks which must come equipped with a heatsink.

Just minutes ago, I learned that the Tekin R1 Pro esc with the Tekin bruhless motor got in the 4th place in a 24hrs endurance race( over 350mph and 70 battery packs). It was said that the system worked flawlessly despite the fact that it does not use a heatsink. It took 1st place for the first 2hrs and then the car crashed. For the last 22hrs it kept fighting for the top position, but it managed to occupy the 4th place in the end.

Not half bad, really.

[Procharged5.0]

That's a great showing.

BTW, did you mean to say over 350 miles and 70 packs?

[Sylvester]

That sounds pretty good! I wonder how a MM would do there?!

[neweuser]

I wonder if Mike (RCM) would have an opinion on this esc?

[captain harlock]

Sorry, it is a 350 miles( not mph, LOL!).

Jim Campbell stated that the R1 Pro is spicifically made for racing and not bashing like other speedos( as if he referring to the Mamba!?!).

neweuser, Mike might really carry these controllers, but I doubt it'll be as durable as a Mamba Max. It's made for 1/10 racing machines only.

The R1 pro specifies the on resistance of 0.00005 ohms. That's 0.005v dropped on the ESC at 100A, which is 0.5 watts!

the most important thing is how and how fast the fetts hit the full conduction. total losses will be way more than .5 W. It's very hard to get the high frequency switch on/off process to be 100 percent clean .. (but i don't really need to tell you that.. ) :p

Yeah, I tried to mention that too, but it's hard to picture if you don't see a waveform and/or understand what causes heat. Not too many people know what slew rate is. So I didn't spend too much time on the topic. Basically, I was comparing the MM specs to the R1 Pro spec outlining the substantial difference in the resistance since those are noticeable numbers.

And yes, the higher the switching frequency, the harder it is to get a perfect square wave.

Hey, Brian and Rene, what did you major in during your life time in college?

You guys really dive too deep in electronic explaination to the point that you make me wonder if you are speaking proper English..:)

I've graduated from a Teachers College in my city with a high grade and I've majored in English studies, such as translation and linguistics( my favourite course during college, espicially psycholinguistics!), so I'm not very informative when it comes to highly detailed explaination of electric reactions and interactions. I can give some advice, though.

I hope I could gain knowledge of EVERYTHING in this world.
But, as one of the Islamic masters usually says: "learn something about everything and learn everything about a certain thing".

wow 5s w/ no heatsink cool i would give it a try for a turing car just to see how it does it seems to good to be true and tekin has a good rep but it is the same way with the quark i says it will do 6s and it will not even fo that plus you need a heatsink on anything lower pretty much so even though it says that does not mean for sure it does it saftly but it sounds cool how much is it.
