Product overview
The RCTimer Multicopter SimonK Speed Controller ESC 40A (OPTO), designated HVSK-40A, controls brushless motors in multicopter aircraft. For installation planning, the controller measures 66 × 26 × 13mm in length, width and height and weighs 29g. Its power stage combines high-power MOS devices with a separate heat sink and a low-resistance PCB and power input. A separate voltage-regulator IC serves the microprocessor, while the main chip uses a high-stability crystal oscillator. It runs SimonK tgy_debug.hex firmware with a dedicated multicopter program.
Battery support covers 2-6S Li-ion or Li-polymer packs and 5-21 NiMH or NiCd cells. The current ratings are 40A continuous and 60A instantaneous for 10 seconds. Maximum supported motor speeds are 210000 RPM with two poles, 70000 RPM with six poles and 35000 RPM with twelve poles. The throttle curve is configurable, and the brake function is removed. At power-on, the motor does not start immediately, regardless of throttle-stick position. BEC type is N/A and BEC output is designated OPTO. The supplied configuration comprises one 40A ESC with a Deans connector; no manual is included.
