Mamba Monster X is the latest 1:8 scale and Monster truck controller capable of 2S - 6S LiPo, with an 8 amp peak BEC - and, it s waterproof*, so you can run your vehicle through morning dew, across soggy snow, or a muddy trail. This is the perfect upgrade for 1:8 scale buggies, truggies and on-road vehicles as well as 1:10 scale monster trucks weighing up to 15 lbs. It also comes standard with a highly efficient, 30mm ESC cooling fan. Mamba Monster X also features updated Audible Alerts that will notify you of possible issues with calibrations and error conditions to help diagnose problems in the field. The Mamba Monster X is now paired with the new sensored 15xx series motors. Now you can have all of the torque and performance you know and love and have even more control! Castle uses the same high quality components as their sensorless motors, such as ultra-thin stator laminations, high temperature sintered neodymium magnet and high RPM ABEC3 bearings. Combo includes required Castle sensor harness and sensor wire for sensored operation.

Mamba Monster X features the addition of a programmable Auxiliary Wire that allows you to make "on-the-go" adjustments to several settings such as torque control, and max throttle, and fine-tune the performance of your ESC right from the transmitter using an auxiliary channel on the receiver. The AUX wire function is disabled by default but is programmable via Castle Link (sold separately). Once you have programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter.

Mamba Monster X can capture and record performance data from your last couple of runs, commonly referred to as data logging. This data can be downloaded via the Castle Link USB programmer; you can use the Quick Connect Duo (sold separately) to allow you to quickly access the ESC's receiver wire without having to disconnect from your receiver. You can then analyze this data and make adjustments to the ESC to maximize both performance and battery life.

Mamba Monster X is telemetry ready, which means owners of the Futaba T4PX Transmitters are able to purchase the Castle Telemetry Link for S.BUS2. Real-time data such as ESC temperature, voltages and RPM can be monitored to ensure performance advantages and spare you the "unknown" parameters that all R/C enthusiasts experience at some point. Telemetry data provides another level of protection and can increase performance.

The 1512-1800kv version is capable of 2S to 6S LiPo and is perfect for 1/8 scale buggies and on-road cars weighing up to 9lbs (with batteries, ready-to-run). It is the perfect motor for racing 1/8th scale buggies on 4s. Paired with our Mamba Monster X ESC you will have all the power your 1/8th scale vehicle demands with the smoother throttle control of a sensored motor.

    A great line of sight phone holder with a few flaws.
    Overall this does the job and is priced affordably the pros and cons are as follows: Pros: Strong magnet Solid construction Great for line of sight Charges well Cons: Charging cable is not long enough to route inside my car holder tends to droop down slightly with my phone on it (Pixel 7), not so much that it's failing but just not holding it's set position

    Does not swivel and slow charger
    As mentioned in another review, you cannot change the angle of the phone so it faces the other way since it does not swivel. Wish I wish I would have known that before placing it. Also, the charger is REALLY slow. It’s slower than the MagSafe chargers I have in my house. I’m not sure if this is defective. I only used it on my way home from work, and I will be returning it.

    Almost perfect
    Style: Screen+Charger
    Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

    Great Phone Mount

    Works great! It’s been a fantastic upgrade for my car. The installation was quick and seamless, and it fits perfectly with the Tesla interior. The wireless charging stays fast and stable. I highly recommend it.

    Almost Perfect But With Workaround it Rocks
    Style: Dash+Screen+Qi2 Charger, Style: Dash+Screen+Qi2 Charger
    This works almost perfectly in my Tesla, with one small tweak for hot summer conditions. It holds my phone very well overall—I position it slightly off-center at about the 10 o’clock position. However, with a larger phone like the Galaxy S25 Ultra, the combination of weight and summer heat can cause the mount to slowly rotate as the suction cup loses some grip. I found a simple fix that works extremely well: applying a small amount of rosin (the same kind used for violin bows) to the friction point where the rotating arm meets the suction base. That added grip completely solved the issue. Now the mount stays exactly where I position it, even in the heat. Solid product, and with that minor adjustment, it performs exactly how I need it to.
