YEP 120A HV (4~14S) Brushless Speed Controller (OPTO)

YEP ESC series offers a super smooth linear throttle response 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 an optional programming card or by transmitter stick inputs.

Features:
• HV capability for use with up to 14S (51.8V) LiPo
• Optional programming card for convenient setup 
• ESC had separate programming lead built-in so there is no need to unplug from RX
• Super fine throttle resolution provides first-rate and highly accurate linearity 
• Super smooth adjustable start-up mode
• Constant RPM mode (governor mode)
• Adjustable F3A brake.  
• 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    
• Active free-wheeling circuit allows for unlimited "partial load" capability
• LED status display  
• Adjustable motor timing from 0° to 30°  
• Blocked rotation protection (senses a jammed motor and stops motor rotation)  
• Over-temperature protection and overload alarm  
• Anti sparking circuit: reduces connection sparks 
• Throttle signal loses protection. If the signal is lost for 3 seconds, the power will automatically cut-off.  
• Safe power-on. (Motor will not start until throttle is returned to lowest position)
