| Tekin RS systems- Sensored control, Brushless reliability I have been testing the Tekin RS esc and motors for a while now. It is actually the ESC that I have been using with my prototype sensored motors. I have to say it is the finest do it all ESC available right now. The short of it- control brushed motors, sensorless brushless, and sensored brushless. 3 cell lipo max input, fully adjustable, and AWESOME for crawling, racing or bashing. The button programming is super easy and fast, for those days when you want to swap out batteries or motors on the fly. Dimensions: 1.3 x 1.00" x .45" (33 x 25.4 x 11.5mm) Weight: 2.0oz with included 12G wiring TINY!! I am currently carrying the 21.5 motors in combo form, as they are plenty peppy and fast with a 3 cell lipo. If you want me to get the 17.5 or any other motors in just tell me and I will order them up. For more detailed specs, just click the pic and you can read up on all the particulars. |

Nice John I have the 21.5 system in my SCX-10 and its a blast to drive. Has more wheelspeed than a 35t and will creep slower than a FXR and 35T. Im really happy with it. |

What kind of 35t are you comparing it to? It is a really nice combo. I get tired of fooling with brushes on my play rigs, and this combo is the ticket. |

I would like a nice hand wound but I have a 7t puller waiting to go in. | |

The 7t has better low speed control than a handwound 35t, so you aren't missing anything except for power and an ounce of weight |

How is the programming on the controller? Does the ESC have decent braking? The sensorless should be smooth starting like a brush motor right? |

I miss my 7T puller still. i have this system with a novak goat 18.5 motor in my 1.9 tuber, and i cannot get the thing to stop cogging. I don't know what I am doing wrong. I guess it is hard to compare when I have been running the 7T pullers since I got into this sport. I just think the 7T puller is by far the best do it all motor out there. Thanks John for making such an amazing motor . If I dont get the issues worked out of my tekin rs and novak system I will be buying another 7t puller again. |

This may be hard to do since you are using a Novak motor, its probably not labeled A, B, C. You may have to swap them untill it runs smooth. | |

put it into sensored mode, instead of hybrid. Give that a shot.

Little slow on brushless stuff, what does the 21.5 compare to in brushed motors turnwise? May pick one up Friday for the Losi I got ordered.

I checked the box for sensored (enabled) i am using version 3.24 any other suggestions? I am running a max amps 3 cell with I think a 50c punch and should have enough power. I also tried my 2 cell pack thunder power v2 extreme 2200 25c and 50 burst. Last edited by Chaotic Crawlers; 05-12-2009 at 07:07 PM. | |

If you cant get it working try sending a PM to Randy P. He is the Tekin Tech support guy. He can also hook you up with the 1.94 software. | |

Compared to a brushed motor, it is kinda like a 30 or 35t on speed. Since the ESC can kick a lot of timing onto the motor it is hard to compare. I like the 21.5 or the 17.5 for most crawling situations. I am working on the issue. The latest firmware seems to have helped it in sensored mode, so contact Tekin if you need newer firmware. | |

Sorry to bring an old topic back, but I've got a quick question for you. You are using the RS ESC, not the RS-Pro correct? Is the internal BEC strong enough for most of your needs? I would be using it in one of the Losi 2.2 crawlers with dig... would you recommend getting an external BEC, or will the built in one handle the duties fine? Thanks in advance for any info. |

Both servos would be digital... probably a Hitec 5245 for the dig, and the Hitec 7955 for the steering. And the battery would most likely be a flightpower or Thunderpower 3s 1350mah lipo.

| Definitely go with a BEC then;) I tried mine without a CCBEC in the living room, and first time I stuffed the tire into the couch it overloaded the internal BEC.

Interested in how this set up works in a Losi. I hate to have to go brushless, but if it is the best option than so be it. I am used to wheel speed, so I think I should probably go with the 17.5 over the 21.5?

I'm using the sensored only, no drag brake, timing at 0. I also hae a Common Sense BEC putting out 6V to the Spektrum Rx, Hobbico CS-170 and Losi MSX servos. Came in fourth at it's first comp which was one of the most diffiult the club ever had. I think it came in second among the shafties. | |
