YEP ESC series offers a super smooth linear throttle responce making them exceptional fixed wing and helicopter ESCs. The features offered in this ESC are only matched by the most expensive european brands at a fraction of the cost. The super smooth soft start, along with its ultra high resolution throttle response puts this ESC in a class of its own!
YEP ESCs are built with the highest quality components to ensure true-to-rating current handling and high efficiency operation. Although quality is a tag line mentioned by many manufacturers you'll notice the difference the moment you remove the YEP ESC from the box.
All YEP ESCs can be programmed via optional programing card or by transmitter stick inputs.
• Optional programming card for convenient setup
• Super fine throttle resolution provides first-rate and highly accurate linearity
• Super smooth adjustable start-up mode
• Constant RPM mode (governor mode)
• 3 steps adjustable normal EMF brake
• High anti-interference capability
• Low voltage cut-off protection with automatic adjustment for NiCd/NiMH/Li-Ion/LiPo/LiFePO4
• Soft cut-off option at low voltage, slows motor RPM gradual rather than hard cutoff (LVC)
• Low voltage cut-off can be disabled
• Variable cut-off voltage / cell
• Adjustable motor timing from 0° to 30° or Automatic timing
• Motor reversing from ESC (no need to change ESC/motor wires)
• Throttle signal lose protection. If the signal is lost for 3 seconds, the power will automatically cutoff.
• Safe power-on. (Motor will not start until throttle is returned to lowest position)

YEP programming card required to access the full suit of programming options.
The unit is indeed very small and light. It is one of the very few lightweight ESCs supposedly able to whitstand more than 3A.
*However*, the unit I got simply could not drive an OverSky AP 05 5000 Kv efficiently on a single LiPo cell.
The max amp draw was about 2A while it should have risen to 3.5A.
The ESC got pretty hot, presumably triggering overheating protection and thus limiting power to about 60pcnt of the actual motor capabilities.
Besides, the beeper would work erratically (sometimes fine, sometimes barely audible and sometimes plain mute).
Finally, the spec is *wrong* about programming, as other comments/reviews have already reported.
The actual programming options are limited. Notably, there is no way to reverse engine rotation without physically inverting the wires.
Very small and light regulator. Many available settings even to set them is very tricky. But when you realize how its very quick.
