Harrier-eXTrem ESCs are Maytech's premium, top-tier speed controller line. Built only from the highest quality components using the strictest of design and quality control standards, HX Series ESCs are a professional-grade multi-rotor speed controller designed for the most demanding applications.

NOTE ON FIRMWARE: Flashed with a custom version of SimonK firmware, these ESCs are capable of over 500Hz refresh rates, and Altitude Hobbies has tested these ESCs and found they eliminate common timing issues plaguing many users when running high pole-count motors with most other multi-rotor ESCs currently on the market. We've tested them on both 14 and 24 pole motors (including KDE XF3520 & 4014, and T-Motor 3510, 3515, & 3520) with no commutation errors experienced. Each size is also available with popular BLHeli firmware.
