You can set it up without a programmer. It has a few buttons on it and LEDs. Stormer hobbies had them yesterday and they were also the lowest price I could find

As far as people liking this over the Novak Crawler....I am not going to speak against any ESC manufacture here. Both Novak and Castle Creations where instramental in getting the Crawling ESC's to us in our small crawler market and for that I have not bad to say about them. I personally looked for an ESC to fit all my requirements and Tekin did it.....In every case. I hope this helps. | |

G'day all Just got my FX-R, i read that it will run 3s Lipo, but in the instructions it say's 2s lipo, which is right? Has any one run with a 3 cell lipo yet?, and what happened? Thank's Chris |

We only warranty 2S, I'm going to talk it over with everyone here on how we're going to handle 3S with lathe motors and such, it seems to handle it fine. I'll let you know guys! |

Well if your running the ESC with these 35T,45T,55T motors you should be fine. At 3s you are not getitng a 3amp BEC anymore, just keep an eye on your heat as it'd get hot really fast with those big servos yanking on it. We'll look at any failures from the rock crawling community individualy just so we can better ourselves in the application and for further development. We aren't seeing any failures due to abusive actions as a matter of fact I can't recall any failures period coming in from the crawler community. In short yes we'll honor the warranty on a reviewed, individual basis. |

I ran my FX-R on 3 cell lipo with a 45turn at the BPRCA comp on Saturday. Worked absolutely flawless. I ran it with a Castle S-Bec so I couldn't tell you how it worked with my big servos on that part, but the throttle is super smooth from bottom to top, the min drive speed is very low, and the drag brake is solid. I ran it on 65% and for a demo after the comp I set the rear wheels on a ledge with the rest of the rig dangling over and the brake held it there. I might dial it down a little because it seemed a bit locky for me but its nice to have that ability.

Out of curiosity how would changing the battery voltage change the amps of the BEC? I thought the BEC throttled down the amps to 3 regardless of the battery used. I was also curious if the 3 Cell cutoff built into the FX-R functions as it should. I have not had any problems myself but I was just curious to know if we should pay attention to this as well. Thanks for the clarification. |

The amperage out and voltage in are directly and inversely proportional. If Tekin assumes 7.2v in to get 3a out at 6v we can do a little math to figure the rest out. A linear BEC bleeds the extra voltage as heat, so with a higher input voltage comes more heat. What Tekin is really telling us is the average wattage that the BEC circuit can dissipate as heat. Wattage = Amps x Volts 7.2v-6v = 1.2v difference 3a of load 1.2x3 =3.6 watts (of heat) 11.1v input-6v = 5.1v 3.6w/5.1v = 0.706 amps out to make the same heat So if you run a 3 cell lipo you will have less than an amp available. You could run a CC BEC to get your steering power back because it is a switching regulator and does not have such losses. |

Sounds like I need to grab another CC BEC Last edited by kaetwo; 04-07-2008 at 07:28 PM. | |

Switching are more efficient when the wanted voltage drop is more than 10-15%. With a 3s lipo they are certainly more efficient.

I can help you out with the ratings if you need. It will of course be dependent on vehicle weight and wind, but we could get some general guidlines going. A 35t only turns 1500kv, so it isn't exactly a hot motor. | |

I will give it a shot when I get mine, but your throttle finger will probably dictate whether it works more than anything.
