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 :|

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. :)
