Tobey from Banggood invited me to try the Sunrise Sword 60A Brushless Speed Control.

In summary, this is a heavy duty controller that appears to be deluxe and up to the task. It is a product designed for helicopter and airplane models, but it is set up for heli use with the slow heli start up. I had no problems using it in default settings, but I would order the program card for it in case you want to modify any parameters.

After adding 3.5mm bullet connectors and a battery connector, weight was up to 70g. My digital multi-meter showed both the standard 3 wire and the split connector (see pictures) power leads for the receiver at 5v.

Product features and Specifications

The ESC runs off a 32-bit ARM processor designed to give high resolution for a smooth and responsive throttle. Failsafe from throttle signal loss after turning the TX off took <2 seconds to kick in and power returned to the TX setting almost instantly when the TX was turned back on (using the pictured Lemon stabilizer).

The ESC has regenerative braking, saving power compared with the other regular ESCs. It offers adaptive timing, so as to be more easily compatible with many motors.

The ESC automatically detected a regular throttle input signal from my Spektrum TX/RX. ESC calibration was normal, starting with high throttle and then moving to low throttle after 1st use.

Note: A programming card is used for implementing different settings. I do not yet have the Sword Programming Card, but there are many settings shown in the manual that might be useful, particularly for heli use.
