I have been lurking on different forum to get more information on tekin R1, to make it simple all people that have something to win from R1 R1mt selling give a rather positive point of view (Rc monster mike include). But the very few "independant" customer that are on the forum were dissapointed by the result and the inabiliy to run decently "legal" motors. From a guy who said he is a reseller (rctech forum) the problem is NOT only limited to huge roll out, it touch pretty much all range of motor except the sensorless design (CC CM36 alike)

Fact trie to find a youtube/dailymotion, or whatever movie on internet that prove there is no cogging problem. I have found 0. The 2 available on youtube are old and were made be Tekin ...

Tekin guy are non stop saying there will be an update that correct the problem, great but, it take more than 1 year for CC to get the software fine and running ... it's just too bad for the future of sensorless technologie on race track. Tekin are now doing a range of sensored motor (feigao + tekin stickers ? :( ).
In the best case they might be able to use there experience in sensoreless stuff to make an hybrid ESC that work like speed passion GT

Sorry if you find harsh my post, just my feeling :|

So, you are saying that the r1 speedos are having problems running sensorless motors?

Al,

In rctech.com, there have been some people who are having a lot of trouble with them. Maybe Tekin didn't test the controllers on all the motors available before they released them.

Lutach make it short, and it's exactly that.

I see.

I'm planning to use the R1 Pro with a Kontronik Kira and a NEU 1115/1y motors in my 1/8 onroad car.

I don't know if I should just go with it or get a Mamba Max instead?

I don't think Mike would blow smoke up our a$$ about this controller. He has plenty of speed controllers for sale. The R1 won't make or break him. The R1 may have problems in some applications, but if Mike says it worked fine for him in his truck, I believe him. :yes:

I would love to see a video of Mike using this controller in a RC. Videos can prove a good point if something does or doesn't work.

I just want to see this controller in action. I haven't seen a video of it yet.

Well, The hotwire software is available on tekin website, I'm looking forward to know if the potential update it contain while help !

Just few quote from Tekin support forum

"I agree with Canon. My R1 pro cogs about 1/2 throtle and this causes the car to become very unstable and throws the back end out. I am a bees gorgeous away from sending mine back.
The only light at the end of the tunel seems to be this firmware upgrade. When is Tekin help address the issues we are facing with the speedys in Australia? It seems that our batch came out with a firmware version that it shouldn't have? I spent 5 hours testing mine with different profiles and settings today. Nothing I did made a difference. I know that my motor is fine and also my radio settings are fine. They work well together with a Sphere."

"I received my R1 Pro 1 week ago and was very excited to go racing Wed night. Hooked it up as described to my Novak 10.5 and noticed right off the bat that the acceleration was very slow. Meaning you could hear the time delay it took the car to spin-up which is far slower them my Novak controller. I adjusted everything possible and was not able to change the start-up speed. When the races started cars behind me actually rear ended me because the car would not accelerate fast enough. Of course i did experience the cogging affect everyone is seeing also which from a stand still is tolerable. The part that is not, is if the car is rolling backwards it will not start until the motor has stopped. This effect and the slow acceleration are just not tolerable."

I got R1 pro for two weeks ago, I found it move backward then run at start up every time and it no respond for 3 to 4 seconds after a heavy brake or after a accident. I am playing with 5 cells and 3.5 brushless motor.



People could argue that it will be fixed soon, maybe, but even if it's high performance ESC the price seem to be a bit high and the wire is sold seperatly (I guess I'm too much used to CC stuff :P)

I have one here that I am planning to run on 5s in a 1/8 buggy. I am just waiting for the Hotwire to be released before installing it. I want to set a proper LVC for 5s lipo and the manual programing does not allow this. Hopefully the Hotwire is released soon. I have had one ordered and on backorder from tower for 6 weeks now.

I will for sure post my results when I get anything to report. I have been doing my own web scan for problems with the R1Pro and everything I see is from guys running 4 or 5 cell NiMH and very low turn motors. I really haven't seen any other complaints. I will be running a Hacker 10XL on 5s an I'll let you know how it works. I replaced the stock capacitor with a 1000mfd 35V cap to handle the higher voltage.

Here it is all wired and soldered up just waiting for the Hotwire so I can program it properly for my application.

I bought it used for a very nice price from a guy that had the same problem with the 5 NiMH cell oval carpet racing application with the ultra low turn motor. Unfortunately the guy had some pretty sad soldering skills and scared the front of the controller with the soldering iron. (but it shouldn't effect the function)

I respect your opinion for sure, but you must not know me very well to suggest that I posted my results for my own benefit("something to win" as you put it) - I didn't have any to sell when I posted the result as a matter of fact - it was a few weeks before I actually had any additional units in stock. I don't work for Tekin, either - and I have managed to survive in this brushless business for a few years now - long before this product was even so much as a thought or idea in all reality. I simply had nothing to gain by posting the information - and as a rule I simply DON"T post fiction at all.

I simply stated that for me - in my 3905 emaxx test truck - I experienced the performance I expected - there was no noticeable cogging and the results were very smooth - as smooth as any other sensorless controller and smoother than most is what I wrote IIRC(the new Castle firmware was also not available at the time of my posting - Castle controllers frankly were far worse than my R1Pro BEFORE the latest upgrade). I tried slow starts, fast starts and everything in between. I drove the truck with the intent of "finding out" what the controller was all about in the session. I used a 35 volt 1800mf capacitor on the controller with 4s lipo, a 22 tooth pinion on the stock spur(68t?) and a KB 7xl motor for the test session I wrote about. I didn't try it in a TC or with a Novak motor, nor did I make mention of these setups in my assessment. No smoke and mirrors or any "sales mission" were part of the equation - I simply wanted to make a comment for the users here to digest - from what they hopefully consider a reliable and experienced source.

I can't argue the results or posts of others - I can only tell my own tale. I can promise that my particular setup DID NOT suffer from a bad solder job, poor connections, poor batteries, inadequate capacitance, stuck drive train, bad bearings or any other potential pitfall that can and usually does lead to problems such as cogging, delay or otherwise sub standard performance. I did install the largest pinion I had available for the test, though. My controller in my truck worked as I described it. Period. Get your video camera and come watch if you like - I will gladly drive it for a movie. :)

You have pics of your instal with the R1PRO Mike?

wow, that cap really shows just how small the esc is.

Excuse me if this seems strange to me. So am I reading this right. The R1Pro is the same esc as what the MT will be!? I eman I have been waiting to see this come out and last I knew it wasnt availabe and now I am reading this all and it appears that you guys are stateing it is the same ESC unit. If not whats the deal with the MT anyways?

The way I understand it is the MT will be the same basic electronics as the pro, but with a different case that has heatsinks. I dont know for sure but that is what I have been hearing around the forums.
