RACER TESTED - BASHER APPROVED

With the introduction of the MAMBA MONSTER X 8S any R/C vehicle weighing up to 25lbs, and running up to 8S LiPo, is fair game. Drive fearlessly and punch that throttle! The MAMBA MONSTER X 8S utilizes Castle’s breakthrough technology CRYO-DRIVE™.  By reducing the rate at which the ESC heats up and removing heat more efficiently, your setup will be able to handle higher gear ratios, in heavier vehicles, with longer runs.  These software advancements work in parallel with a unique open housing design to allow increased directional airflow to cool critical components. With the integration of a 40mm cooling fan and a forged elliptical fin heatsink, the design maximizes airflow throughout the system, taking thermal performance to a whole new level.

High-performance demands high quality and this ESC was designed with durability in mind. Constructed around a robust aluminum casing, the epoxy potting guarantees protection around the circuitry and ensures all-weather use. Mamba Monster X 8S is a workhorse, it will dominate in the harshest of environments.

You can easily optimize the ESC for any driving condition, from rugged terrain to smooth pavement to the perils of rock and gravel. Create, save and download setup profiles through the Castle Link Programming Suite on your Windows™ PC, or wirelessly with the convenience of the new B-Link™ Bluetooth™ Adapter and Castle Link app for Android or iOS. 

Additional tuning flexibility awaits you with on-the-fly adjustments from your transmitter via the Auxiliary wire. Simply connect the white signal wire to an open radio channel, and enable the feature in Castle Link by selecting what Auxiliary function you would like to use. Access programming parameters such as Torque Control, Max Brake or Rock Race Mode. Optimize your vehicle for any racing or bashing application you can imagine!

When paired with a Castle 4-POLE 12-SLOT SENSORED MOTOR such as the 2028-800KV or 1515-2200KV, users with heavy, high-performance rigs will experience controllable low-end ranges without sacrificing power, punch or speed.  SmartSense™ mode uses the motor’s sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability. Once the motor is spinning, it seamlessly transitions to Castle’s ultra-efficient sensorless mode. You’ll put more power to the ground, where it should be, instead of wasting it through raw heat and RPMs.

 Whether you are burning out, dropping the hammer, trigger happy, powering out, on-the rocks, off-the-rocks, wheeling or mud bogging - MAMBA MONSTER X 8S is ready to test the limits of your R/C car or truck.

Note: While many users have utilized the Mamba Monster X 8s in extremely high speed applications and drag setups, it is NOT intended for this application. As such the Castle warranty does NOT cover failure when used in high speed or drag applications.

No flaws, not high end
Color: Pink, Size: Medium
I nabbed this for my in shape 14 year old son who had an upcoming wrestling banquet. It fit very true to size for him however as a low-mid grade dress shirt it had little flex or mobility across the chest and that’s ok, this is an entry level dress shirt and perfect for this and similar events. The color was vibrant and well saturated, and the fabric itself was thin enough for some transparency but thick enough to be considered medium weight. It would not be a cooling dress shirt. It did not have a soft hand, rather a sturdy rougher feel akin to a dress shirt a restaurant server would wear and laundry frequently which is also ok because it is exactly what a polo in this range should be. If you are looking for a flexible chest and soft touch you will need a better fabric blend and you pay a lot more for that. The buttons were nice and collar looked good. I would recommend this for any average event or occasion or even for work. If you are looking to impress on an interview or a date or during high heat you might need to look elsewhere. For what it is it’s perfect. Buyer and shirt need to remember this and keep it in its shirt lane.

Good shirt, not great, but it was never trying to be
Color: Navy Blue, Size: Medium
Let’s start with the fabric. The 50/50 cotton-polyester blend sounds like a compromise, and I suppose it is — but it’s a good one. You get enough cotton to feel like an actual shirt and enough polyester to keep things from turning into a sweat tent in the heat. It holds its shape after washing. No complaints. The collar is a genuine highlight. The pin tips keep the points flat and symmetrical, which is a small thing until you’ve owned a shirt where the collar curls after two washes. You’ll notice it. There’s also a hidden plaid print under the collar — a subtle detail that’s only visible when unbuttoned. Unnecessary, but charming. Fit is true to size. Order what you normally order. It’s versatile enough to tuck in for the office or wear loose on the weekend. Not going to replace your best Oxford. But at this price, it was never trying to.
