| Greatscott's RR10
I finally bit the bullet and got a Bomber kit... Axial RR Bomber Kit by GreatScott, on Flickr I was on the fence about going with the kit or RTR. Doing some comparisons between the two it became clear that the kit was the better deal, better shocks, aluminum links, reinforced trailing arms, better tires and wheels, and I would have just ripped the stock electronics out anyways, the kit seemed like the clear choice. I will be running this with my DX5R (4-ch DSMR RX) and 3S SMC lipos, I have a short shopping list of what I need to get for it to run under it's own power and looking for some educated input... Motor: - I am thinking about running a brushed motor, but might just bight the bullet and go with the 1406-2280kv. The last sensored BL system I had the ESC was waterproof, the the sensor cable was not, is this system fully waterproof? Servo: Those big tires need power to move, I was thinking about going with a Savox 1270TG. Is there a better servo for the money? Winch: I want to use this thing for C3, and that means a winch. What is a good system and where to mount it? BEC: I know the Mamba X is popular, has anyone found a need to run an external BEC with it? 8 amps seems like it would be more than enough. Other Stuffs... The beefed-up trailing arms are a nice touch, but they are still plastic, thinking about the Gucci VP set. I will likely throw some lights on this, but it is not high on the priority list. What else should be upgraded or modified right out of the box? |

For servo I run a ProModeler S470 on 7.5v, and so far have not wanted for more torque. As an added plus, it's water resistant and is also the quietest servo I own. I run it off the BEC in my Mamba X. For winch mount I think wertymade makes one. For trailing arms go VP or supershafty. Sent from my Nexus 5 using Tapatalk |

Wertymade does make a servo winch mount. Wertymade RR10 Bomber Stainless Servo Winch Plate And HeyOK has a few options for winch controllers... You can get one with a small keyfob to control it or have it controlled via Tx. He also sells them with a servo. |

Many thanks for the suggestions guys, keep them coming. I went ahead and bought a Castle 1900kv sensored motor, I figure on 3S it should do well on the rocks. I was thinking about reliving my early crawler with this rig, when I had my AX10 with a HR dig unit. Does anyone make a dig unit that bolts on, or a dig transmission? |

Axial Dig - you'll need to swap in a Wraith transmission to use it - which is easy enough, and fairly commonly done: Axial Racing - Dig Component Set Vanquish has a fancy one, they explain what needs to be done on the link: Hurtz Dig V2 Black - Vanquish Products |

I kinda wish I had the SSD trailing arms, setting the tension on the VP's with the set screw was kinda a PITA. I would get it just where I want with the set screw, lock it down and it would be overlight tight. Rinse and repeat a dozen times before getting it where I wanted it. Quote:
I just installed the Mamba X and 2850kv. It is plenty fast just on 2S for rock crawling stuff, and a blast on 3S with more open terrain. I'm running stock RTR gears. the 1900kv should be even better for crawling on 2 and 3s and plenty fast on 3s still. I plan on going SSD 2 speed instead of wraith with dig since I don't do a lot of technical crawling, but more general fun rock bouncing. Last edited by angrchair; 04-09-2018 at 09:04 PM. | ||

Even though the MMX has an internal BEC I’d still get an external BEC just in case the internal one gives out, and ruins the resale value of the MMX. I like my RCs to be more modular, I don’t really like taking things apart that don’t have connectors installed. I’ll avoid un-soldering, and re-soldering wires anytime I can. |

Shocks springs... My kit came with Kings with blue springs that have a yellow dot, they are 3.27lbs and are too stiff for crawling. What is a good spring setup for crawling? I was thinking about going with 2lbs springs (AX3021, I already have 45wt in the shocks. | |

My build continues in slow motion... I just built an internal spool servo winch that will be mounted on a plate under the hood. It is built on a Savox 150oz (@ 6VDC) servo, it might be a bit under powered, but I didn't want to spend too much money on my first try out of building this style of winch. I might pop for a better servo if this build works out ok. I am waiting on my premium Chinesium beadlocks, Amazon says they'll be here sometime this year.... Mamba X mounting... What/how/where are you mount the Mamba X? The best place I can find is on top of the RX box, which isn't too bad, but it bugs me that it covers two of the RX's bolt holes. Is there a better way/place to mount it? |

You want it kind back over the transmission a little, or the battery will hit the ESC. I got mine right on the first try. Last edited by angrchair; 04-24-2018 at 10:28 PM. | |

Progress continues... I have everything on the lower frame mounted up. I have gone through and programmed the Mamba X with what looked right, uploaded and installed the latest firmware. Fired everything up and calibrated the radio to the ESC, everything looks like it is doing what it is supposed to except for the power switch, which looks like it is broke in the 'On' position. What settings on the Mamba are recommended for crawlers? And, I wasn't sure about the sensor setting. RR10 Bomber by GreatScott, on Flickr RR10 Bomber by GreatScott, on Flickr I made an attempt at an internal spool winch, it works, but it is terribly slow and needs some refinement before it goes into a crawler, so I bought an HR dual motor winch. I will use a small QuicRun ESC for a motor contoler for the winch, the only problem is the double-clutch reverse, which isn't that big of a problem, but there are no programming options on this ESC other than NiMH or Lipo mode. RR10 Bomber by GreatScott, on Flickr This is sort of how the winch and ESC will sit in the Bomber... RR Bomber by GreatScott, on Flickr And finally, wheels! There were 46 screws per wheel... Luckily it only take four to take them apart. RR10 Bomber by GreatScott, on Flickr |

These guys: https://www.amazon.com/RCLIONS-inche...eadlock+wheels Other than a lot of screws, they were REALLY easy to put together. The inner screws really are not needed other than to provide weight. I have a set of their 1.9s on my TRX4, they look good and have had no problems with them.

I bought similar ones, however - mine are 25mm wide, not 37mm - which means I'll have loads of fun trying to fit them to tires once those come in... (ACK!) Cheap wheel mix & match Definitely going to pick the narrowest 2 sets of tires that I have and use them... My other 2 wheelsets include Gearhead RCs (nice and wide!) and Incision Methods (somewhat wide). The original Vanquish OMFs were also super narrow, many people ran widener rings which are nearly impossible to find. |

I have most of this thing together. I had to pull the cage off last light to do a bit of reprogramming of the Mamba X, and wanted the BEC set for 7.5VDC instead of 6VDC. I wish there were more voltage steps available for this ESC. Is there a fix for those cheese-assed ball-ends that are put in the shock caps of the King shocks? |
