Then the Mamba Monster 2. Now there’s the Mamba Monster X. As revolutionary as it’s predecessors, the new Mamba Monster X Electronic Speed Controller (ESC) takes Castle’s legendary “monster” performance to a whole new level. The waterproof Monster X is capable of 2S LiPo up to a maximum of 6S LiPo and is the legendary “power up” for 1/8th scale buggies, truggies and on-road vehicles as well as 1/10th scale monster trucks and R/C monstrosities weighing up to 15 lbs. The new Mamba Monster X provides even more extreme performance than the Monster 2. Most notable is the addition of a new, programmable Auxiliary Wire that allows users to make “on-the-go” adjustments to several settings, such as torque control and max throttle. The new Auxiliary Wire allows users to fine-tune the performance of their Monster X 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. Once the user has programmed the functionality of the AUX wire, that setting can then be adjusted on-the-go from a compatible transmitter. The Mamba Monster X also features updated Audible Alerts that will notify drivers of possible issues with their calibrations and error conditions to help diagnose problems in the field. Review: Awesome esc - I put it in my erevo 2.0 with xt90 connector and noticed a huge difference in torque with stock motor. I noticed the motor runs much hotter. I wouldnt run it hard and long without a motor fan.

I’m not familiar with the stock gearing on that model, but you can probably gear for about 45mph max speed on 6s and be ok. Any more and you would at least need a cooling fan on the motor. **Q: Can I runs 2 s with this system** A: You can but it wont have the power you want.. im running 4s 9000 mah on my summit and its bad a $$ **Q: This is 1/8 scale sensored esc ,will it work on 1/10 castle sensored motor,,** A: Yes I have run my 1/8 esc in my slash so I could run 6S on my 2400kv in my slash I don't think castle will cover a break on that combo tho but insanely fast ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome esc *by M***. on October 5, 2019* I put it in my erevo 2.0 with xt90 connector and noticed a huge difference in torque with stock motor.
