Firma 2-in-1 Brushless Crawler Motor/ESC: 2300Kv

The Ultimate Compact Crawler Solution:
The Spektrum Firma Sensored 2-in-1 System is specifically engineered to be used with 10th scale Crawlers and Scalers. Featuring advanced Field-orientated Control (FOC) and professional drag brake performance and torque control, all while being fully waterproof.

The compact 2-in-1 design grants builders the ability to reduce clutter and components, giving you the most room for scale accessories and customization. The integrated design makes the size similar to a 550 can size motor, making it a easy drop-in option for most 1/10 scale crawler, scaler and trailer models.

Available in a low speed 1400Kv option for extreme slow speed and high angle of attack performance. And a high speed 2300Kv for excellent control for trailers and rock bouncers.
