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. This ESC has a 3A BEC for solid reliable servo power. 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
It's NOT a switching BEC, it's a linear one.
There are three 78D05 linear voltage regulators on this board.
Upside: you can just connect multiple of these ESCs in parallel to get more current.
Downside: heat, the regulators 'burn' the difference between 5V and your input voltage, e.g. running this on a 4S lipo (16V) means that 11V get turned into heat. If you follow the spec and draw 3A on a 4S lipo, the board turns 3A*11V=33W into heat. I don't think this would survive very long.
good esc for super simples but not same performance according to Turnigy plush

I put two of these in a Dynam A-10 with the stock 64mm 6 bladed edf's & a Turnigy P2627L EDF Outrunner 4200kv for 55/64mm with a turnigy 3000mAh 40c lipo. Esc's are giving out 34A at WOW & come down a little hot on hard flying but are doing the job and keeping the plane really low on weight. great price I love these blue babies, go for it. I will by buying more!!!
