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 tagline 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 programming card or by transmitter stick inputs.


• Powerful 5.7-7.4-8.0v/12A Selectable BEC
• Optional programming card for convenient setup
• ESC has separate programming lead built-in so there is no need to unplug from RX
• Superfine 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 gradually 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) 
• Motor reversing from ESC (no need to change ESC/motor wires)
• Over-temperature protection and overload alarm 
• Anti sparking circuit: reduces connection sparks (for HV ESC)
• Throttle signal loss 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)


Max Cont Current: 120A
Max Burst Current: 135A for 10 Seconds
Input Voltage: 2-6 cells li-XX or 6-16 Ni-MH/Ni-Cd Battery

Quality item

Small size, jumper makes it easier to select bec output, the overall form is not good with the large electro cap under the pcb (bec output). That cap could be removed from pcb and fixed on the program cable (of the bec). However, the whole package is very strong very accurate and very efficient. I dont think you can go wrong with yep.

YEP 120A LV (2-6S) Brushless-Regler mit zuschaltbarem SBEC

Dec 16, 2020

Keine Bedienungsanleitung, der Jumper fehlt zwecks Einstellung SBEC.
Vorsicht zusätzliche Zollgebühren und Auslagen.
Ich kann das Produkt nicht weiter empfehlen.

The best one of the cheaper parts.

It works in best condition inside its specification. BEC at 8V range is very good and voltage stays stable. Other ranges I did not use.
