Introducing the Mamba XLX2, an ESC that will redefine the limits of 1/5th scale R/C! Engineered from the ground up, the Mamba XLX2 is packed with a potent combination of hardware and software advancements, sensored performance, CRYO-DRIVE and waterproof design that will set a new standard for high performance power systems. The Mamba XL family is well known for its extreme performance capabilities. The XLX2 pays homage to the legacy of its predecessors and exceeds their performance on all levels.
The Mamba XLX2 and 2028-800kv combo is designed for the most extreme and demanding RC applications. The massive motor and high power ESC are capable of pushing vehicles and drivers to their limits and beyond. This is the perfect combo for vehicles weighing up to 30 lbs and up to 8s LiPo.

CRYO-DRIVE, Castle's proprietary breakthrough technology integrates unique software and dedicated hardware to reduce heat and dramatically increase performance. Thousands of times per second, the XLX2 software minimizes the amount of time the electrical components spend generating heat. These software advancements work in parallel with an open housing design which enables increased directional airflow to cool critical components. With the combination of a new 50mm fan and forged elliptical fin heatsink, the XLX2 maximizes airflow throughout the system, taking thermal performance to a whole new level. The results are more power handling, cooler ESC temperatures and longer runtimes and for ultra-high performance.

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 Max Throttle.

Sensored 1/5th scale is here! Pairing the Mamba XLX2 with the Castle 4-POLE 12-SLOT SENSORED 2028-800KV will allow heavy, high speed rigs to 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.

No elastic around the thighs is kinda nice!
Size: 9, Color: Cotton Stretch - Colors May Vary
Great undies! They fit good and the fabric is comfortable. Only thing is that the legs tend to ride up/bunch up with pants on. I got them for post surgery comfort and thats what I got.

Soooo comfortable
Size: 11 Plus, Color: Microfiber - Colors May Vary
Easy on/off because they really do stretch but return to shape. Fit is close to the body but not tight. Love that there is no elastic binding around my legs. Clothes glide over them because they are super smooth. Might never buy another style again.

These were such a RELIEF during a shingles outbreak!
Size: 10 Plus, Color: Microfiber - Colors May Vary
I developed shingles on my abdomen and spent a few days commando because I was in so much pain and couldn’t stand anything against my skin but a nightgown. I had a drs appointment and was agonizing about showing up in a nightgown and bathrobe at the office. Then I I remembered my grandma used to wear boy leg high waisted undies so looked for something similar. These underpants by Fruit of the Loom were inexpensive and seemed to be similar to what I thought might work, so I ordered a four pack. They were very reasonably priced and when they arrived were of very good quality and well made. They were snugger fitting than I had hoped but were very very soft for tender areas on my abdomen. As it was, the snugness was comforting as they stay in place and act as a barrier between the sore rash areas and light clothing. I’ve never experienced the discomfort of nerve pain from wearing clothes andI’m so glad I happened on to these. I’m on the mend now but still wearing these as I’ve developed some neuralgia and these continue to keep me comfortable.

annoyed
Size: 8, Color: Cotton Stretch - Colors May Vary
i purchased the boxer brief. they fit perfectly. they are fairly soft and seemingly comfortable. not too thin or too thick, good for breathability. my biggest issues are the stitching being poorly done, making me worry the longevity will be lacking and the label stating “do not use fabric softener”. the reason i am annoyed though, is the images show pink and gray colors only, which is what i was hoping for, or at least colors only. i understand all multipacks are marked “colors may vary”, but for the love of god, stop putting white pairs in these packs. white, nudes/neutrals, and black should be sold separately in their own packs. i do not want ugly old timey white underwear. i wanted colors, any colors EXCEPT white! i would however, have LOVED an all black only pack!
