Maximum PRO-MT 4X4 Performance
Get your cameras rollin' - this is the ultimate dirt-showering 4S experience.

Called the Performance Build Combo, this PRO-MT 4X4 combo from AMain Hobbies includes the most extreme, no-holds-barred electronics package possible for your Pro-Line PRO-MT 4X4 Monster Truck. This combo comes at a 15% savings over buying each item individually - a savings of over $87 when compared to the original $584.97 retail price tag.

At the core of the system is the fire-breathing Castle Creations Mamba X 1/8 Scale Brushless System, including a 4-Pole 1515 1Y 2200kV Sensored Castle Motor. As a standalone item, the Mamba X offers 2S-6S capabilities, making it a fantastic ESC for a huge range of applications. When paired with the 1515 2200kV motor, 4S is max.

For steering, the Performance Build includes a ProTek R/C "Black Label" 170TBL Servo that provides 600 oz-in of torque with only 6V! But, thanks to the Mamba X's adjustable BEC, you can set BEC voltage up to 8.0V to deliver a crushing 650 oz-in of torque, at 0.11/60 sec speed from your 170TBL.

Lastly, the Performance Build rounds out the combo with the finest ProTek R/C 4S LiPo possible - the 100C Silicon Graphene HV Hard Case. This stunning battery features 15.2V LiHV capabilities, up to 6500mAh of capacity, and an insane 100C discharge rate for maximum PRO-MT 4X4 performance. 


  • Complete 4S Electronics Package for the PRO-MT 4X4
  • 6S Compatible Castle Creations Mamba X
  • Black Label 170TBL Servo Included
  • 6500mAh 4S Silicon Graphene LiPo Included
  • 2S Budget Build also available (AMNPROMTBUDGET)


  • PTK-170TBL: ProTek R/C Black Label 170TBL High Torque Servo
  • PTK-5106-17: ProTek R/C 4S 100C Silicon Graphene HV LiPo Battery (15.2V/6500mAh)
  • CSE010-0155-05: Castle Creations Mamba X 1/8 Brushless Combo w/1515 2200kV Motor


  1. The PRO-MT 4X4 will still require some miscellaneous items; such as tools, servo tape, paint for the body, motor/esc connectors, etc. This combo includes a retail packaged servo, battery and esc/motor only. For the complete PRO-MT 4X4 "Needed To Complete" list, please see the product listing here
  2. Pro-Line recommends that when using 1/8 scale electronic systems with a 4S LiPo power, you switch out the 100,000cst differential fluid for 1,000,000cst fluid for more direct power, and less differential slip.

AMain Pro-Line PRO-MT 4X4 4S Performance Build Combo (1/8 Spec)
This is a great deal I bought this for my proline mt 4x4, then got another for my 1/8 buggy. The servo top notch, even comes with extra wire lead! the hard 4s pack and ofcourse the castle creation system is a awesome deal. You can run this setup up in any 1/8th scale buggy truggy or MT. I also have a couple 6s packs which are great for speed runs, but for just racing, bashing at dirt tracks 4s is all that is needed for must 1/8th builds.)
