| TK powertrain?
I am looking to build one of these. I have experience with 2 built Bronco wraiths with Mambas and Rock 412s and all steel gears, etc. For the TK I want to go waterproof . I think I am going with the Mamba X or Mamba Micro X? and HH PP BP 540 2700kV and reefs T5. With the factory TK gearing, will this be crawler smooth and moderately fast if needed? Will this be a smooth operator? As a side note, I think I am leaning towards mounting the TRX bronco body as well. Last edited by Markeje; 02-12-2020 at 07:41 AM. |

Hard to say since "smooth" and "moderately fast" to you might not be my interpretation of those things. Nearly all my scale trucks are geared for 6-8 mph on the top end, the TK has stock gearing of 44.2:1 so a 2200kv motor on 3S would be my choice. That is enough speed to pop up a lip or jump the occasional gap but not so fast you never go past 1/4 throttle. Brushless doesn't get much better than the Puller Pros, I have never wanted for more low speed control from the 4 I have. |

I would not go stubby, it didn't have the torque of a traxxas 21t 550. Just swapped for a lighter motor. I hat the 3300kv stubby and deared it down to 160:1 after __________________________ Handy gearing spreadsheet |

Thanks for the info guys. I don't have any experience with anything other than my Bouncers and that type of hill climbing. I am not looking to flip, jump and bach this haha. Especially if I put the TRX body on it, but that is not my intentions with this build. But is there any advantage or disadvantage between the Mamba X or Micro X? I am leaning towards the Micro as 3s is what I plan to run...and I would not have to fell the need to remove the fan if i am running in really wet conditions. |

Big difference is the bec, you’ll need one for your servo on the micro. The aux switch is another plus if you need it Hang up and Drive |

The micro has a aux switch too. The mamba x can do 6s, data logging and bigger bec. __________________________ Handy gearing spreadsheet |

Another difference between those ESC's is how much full throttle they can take for an extended period. The Micro X is meant for slow crawling and may get too hot if ran hard while the regular X can take a lot more full throttle action.
