NOTE: A Mamba XLX 2 service advisory has been released - please read this statement from Castle CreationsOur inventory has been checked, and is not affected by the service advisory. 

The Castle Creations Mamba XLX 2 1/5 Scale Sensored Brushless Combo with 2028 1100Kv motor is a product guaranteed to redefine the limits of large scale R/C. Though it shares the name of its predecessor, the Mamba XLX, this is an ESC that lives in a class of its own.   

Reengineered from the ground up, the Mamba XLX 2 is packed with a potent combination of design, hardware and software advancements that will set a new standard for large-scale power systems. Designed for 1/5 Scale models weighing up to 42 lbs, the XLX 2 is an incredible power upgrade for the Losi DBXL-E and Super Rock Rey, Arrma Kraton 8S and Outcast 8S, or Traxxas X-Maxx models! If you are looking for the ultimate upgrade for your speed run, drag racing or off road rigs - the XLX 2 is a true heavyweight, with no contenders.

Castle’s latest break-through technology, minimizes the amount of time the ESC’s electrical components spend generating heat. 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 50mm fan and a forged elliptical fin heatsink, the design maximizes airflow through the system, taking thermal performance to the next level. The results are cooler ESC temperatures, increased runtime and more power handling. 

NOTE: Some vehicles may require aftermarket parts to allow ESC and/or motor fitment.

Castle Creations Mamba XLX 2 1/5 Sensored Brushless ESC/Motor Combo (1100Kv)
I got this for my DBXL-E V1 Which had a XLX esc and a dynamite 800kv motor. This set up had me keeping up with 1/8 buggies on a Track. this new Esc moor combo is insane 1st impressions are good. build quality is evident and the performance is a huge improvement. If I last as long as my XLX I will consider it a win. Got 65 MPH in a 5th scale with average Batteries I could not wait for my new Batteries to make it here. very low temps no cogging on start up.
