Its no “Mystery” where these ESCs are made, now they are available to you at HobbyKing prices.
Built with imported N-Channel mosFET's and an ultra fast Atmel MCU & heartbeat make this a high performance ESC with excellent sync capabilities. Programmable via an R/C controller.It allows you to program all functions to fit your specific needs, which makes it efficient and user friendly.
Features: Extremely low internal resistance Super smooth and accurate throttle linearity Over heat and over-load protection Auto shut down when signal is lost or radio interference becomes severe for more than 2 seconds Supports high RPM motors Power arming protection (prevents the motor from accidentally running when switched ON) New Advanced programming software
Programming features: Brake setting (we recommend using brake for only folding props applications) Battery type(LiPo or NiCd/NiMh) Low voltage cutoff setting Factory default setup restore Timing settings (to enhance ESC efficiency and smoothness) Soft acceleration start ups (for delicate gearbox and helicopter applications) Governor mode(for helicopter applications) Motor rotation( clockwise\counterclockwise) Switching frequency Low voltage cutoff type (power reduction orirnmediate shutdown)
Factory default settings: Brake: off Battery type Detect: LiPo with Automatic Cell Low voltage cutoff threshold: Medium (3.0V/65%) Timing setup: Automatic Soft Acceleration Start Up: Medium Governor mode : OFF Frequency : 8kHz Low voltage cutoff type: Reduce power
There are many who are experiencing sync problems on the latest versions of SimonK!
My Cobra engines do not work with the latest version!
I use BS-NFET V2013-05-15 That works flawlessly!
ps .... all the other girls that I fly with use the same version.

For everyone out there thinking these are the same as the mystery 12a they ARE NOT. These are a nfet esc and the mystery's are now a p/nfet. Search for the rapid esc database and you'll see they take different firmware. Hobbyking bs12a are bs-nfet.hex and mystery's are bs.hex . The mystery esc's are not happy running high kv motors like the zmr/rcx 1804 2400kv, sunnsky 2204 2300kv or the t-motor 2300kv they loose sync. USE THIS VERSION not the mystery's these are cheaper and better without sync issues.
I would move to 4S but then I'll need more items to run FPV. I'll be running 3S with the 2300KV's. I considered the SS2204 1800kv motors but nobody has any tests or reviews on them and I don't know why. I would think running those on 4S or even 3S with 6" props would be even more efficient than the 2300's but without the high end pop. Also, these ESC's are the same as the B-12A from Ready to fly Quads? *******goo.gl/QwhI3B They do the flashing so I don't need to so I'll get from them...
I'm kinda new. Too scared to try 4S right now. My quad that uses 10" props is on 3S and already extremely fast for me. Can easily do 4S no trouble at all, but I just can't take it myself... Would you happen to know if these ESC's the same as the B-12A?
