  • Planetary Gearbox & Dual Slipper Clutch: The planetary gear design provides efficient power transfer and high gear reduction ratio for stable power output. The dual slipper clutch design increases surface friction and provides a more precise holding power. The m0.6 pitch spur gear is suitable for high torque applications.
  • All Metal Transmission Gear Set: The car is equipped with high-strength metal gears for strength and durability.
  • 1.9" Wheels & Realistic Tires: The realistic 1.9” wheel is durable and looks good. The large tire size and rubber compound offers excellent performance and the large blocks tread design provides excellent bite.
  • Aluminum 4-Link Suspension: The aluminum links offer durability and rigidity. The Four-link suspension provides optimal performance.
  • Ball Bearings: Full ball bearings are included to help reduce rolling resistance and provide improved efficiency with longer run time.
  • UPDATED Heavy Duty CVD Shaft: The updated MXS-310094 CVD drive shafts are beefier, and machined from high grade spring steel to offer increased durability.  
  • Steel C-Channel Frame: The realistic steel C-channel frame is durable. Hex machine screws are used throughout the kit to provide torsional stiffness, while at the same time making the truck easy to maintain and work on. Multiple shock mount positions allow adjustability to suit your terrain and driving style.

MST CFX-W Scale RTR Scale Rock Crawler w/JP1 Body (313mm Wheelbase)
This is my 3rd MST CFX W. First was a kit. That i still haven't built yet. Then i bought a gray RTR. Now i bought a blue one. I love these trucks. Put better tires a few adjustments and they run great. Never had a problem except 1 servo. I just like the way the run. But i don't beat on them. No competitions. I wish but too far away.

Awesome truck from MST. I put all the accessories on and some decals. I also drilled out the back tailights so I can add lights. It's a very well put to together truck. The third channel on the radio will be used with a switch to to turn the lights on and off. I'm gonna pick up a couple more for the kids to crawl with.

MST CFX-W Scale RTR Scale Rock Crawler w/JP1 Body (313mm Wheelbase)
This is my first experience with MST, and I am very pleased. It is well designed and well put together. It is very smooth and quiet. It has taken on all the terrains that I have thrown at it. And the only things that I have done to it are add lights and a switch for channel 3 and change the tires. It is great at under $300, and I would love to buy another one, but I cannot see spending $400 on another one...

MST CFX-W Scale RTR Scale Rock Crawler w/JP1 Body (313mm Wheelbase)
Poor turning radius. Not worth full price. Kinda worth it for what I paid, two hundred thirty five. Came properly trimmed - seems to be good build quality for what it is.
