QuadQuestions 18a Simon K esc [RapidESC]

This is an 18A Brushless ESC with firmware by Simon Kirby (available here: https://github.com/sim-/tgy). New firmware means direct, linear throttle response, making it suitable for multicopter use.


ESCs ship with firmware which can be upgraded by using Afro USB Linker. More details about firmware upgrade process is available here: http://www.abusemark.com/downloads/rapidesc_update.pdf

NOTE: This firmware does NOT check battery voltage or ESC temperature. Always use a LiPo alarm and monitor pack voltage while using.

NOTE: These are not I2C ESCs and as such are not directly compatible with Mikrokopter-style interface, however they can be used with I2CPWM converter with MK hardware.
