V1 (with SIMONK FIRMWARE) ESC is specially designed for multi-rotor
copters. The ESCs are loaded with dedicated optimized software, for
extremely high performance on MultiCopters. It will increase the
handling and stability of multirotor greatly. Note: This model V1 is what you want for multicopter use.
This esc is Maytech's 2014 2nd Quarter release with new SimonK firmware
Manufacturers information:
"Multicopter ESCs with NEW Simon K firmware, with active-wheeling function. We cooperated with Simon kirby and developed Simonk firmware specially based on our ESCs.
Advantages of Active freewheeling function:
1. Avoiding lose-power in the ESC
2.
More stable flight. Due to the "active breaking" effect, the
deceleration especially with big motors and props is much faster than
without freewheeling. This massively increases flight stability at
multicopters.
3. ESC is not heating up that much and it is more efficient during part load."
Main Features:
- Handle fast refresh rates. ESCs operate with over 450Hz refresh rate.
- ESC firmware is optimized for quadcopters / multicopters.
-
Excellent Reliability. Our distributors worldwide give us feedback that
our ESCs have the best reliability rate with their customers of any
brand of ESCs they have ever sold.

Eagle-Multi series ESCs come with SimonK firmware and specially used
for multi-rotor copters. As all parameters have been pre-set for

Disclaimer: Before
you buy these esc, you should make yourself familiar with the somewhat
experimental nature of the SimonK firmware. This software pushes the
motor response to the limit. Due to the lack of
overcurrent/overheat/low voltage sensing, it's easier to destroy the ESC
and possibly the motor. Please consult the SimonK threads on various
forums for more info. The esc reseller, esc manufacturer, nor SimonK
will be responsible for any damage that may occur from use of this
product. Please know and accept the risks before using these. SimonK
firmware is the firmware of choice for hobbyists as well as professional
multi-rotor pilots.
