Hobbyking YEP 30A (2~4S) SBEC Brushless Speed Controller

We are now proud to offer our Hobbyking YEP ESC series. With helicopter specific programming options such as super smooth soft start, fixed RPM mode (governor mode) and ultra high resolution, you won't find a better helicopter ESC on the market today!
We have tested these units on our own helicopters and found them to be among the best we have ever seen. The super smooth soft start, along with its ultra high resolution throttle response puts this ESC in a class of its own!

The YEP series ESCs not only offer excellent performance for helicopters, they are also well suited for fixed-wing use with a whole host of programmable features.
Hobbyking YEP ESCs are built with the highest quality components to ensure true-to-rating current handling and high efficiency operation.
All Hobbyking YEP ESCs can be programmed via optional programing card or by transmitter stick inputs.

• Powerful 5.5V/4A Switching BEC
• 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)
• 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) 
• Motor reversing from ESC (no need to change ESC/motor wires)
• Over-temperature protection and overload alarm 
• Throttle signal lose 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)

***This ESC is compatible with both helicopter and airplane models.***

Hello, I just got 4 of these for a quadcopter build, I have programmed them for airplane use on the progcard, but every time I try to program throtle end points via tx the fall back to factory reset and I just can't fly the quad.... Any suggestions please? Did I made a mistake purchasing these for a multirotor????? :(

Hi P3K33, every time you set the endpoints you do a factory reset. So first set the endpoints. Tant remove battery and rx plug. Second plug in the programming card, power up with your battery and do your programming. Thrd battery off, plugt off programming card and plug bach into rx.

I have this YEP 30A ESC and the programming card and it does work with the card except that the card only allows cell selections between 4 and 15 cells, and for this esc, it gives a confirmation for 4, 5, 6, or 7 cells, however, there is no way to choose auto-lipo and so once you choose a cell count with the card the factory setting of auto-lipo count cannot be regained. I went to ni-mh mode which is auto, and it works ok on that but there's no cell protection. Is there any way to factory reset these esc's?

i think you should try to flash it with simon k or just put an buzzer at the batery

This ESC default is 2-3 cells, if it is over 3 then you have to tell it what you are using ie if using 6 cell then program using the card to tell it 6 cell etc.

I have three of these YEP 30a ESC programming card, in F5J type gliders, motor draws 21amp max, Running to UK rules, 'motor can be switched on to save model'. They work OK for a few flights, then loose setting, wont switch motor on, fixed by unplugging battery then re-pug, few more flights, then went onto needing to re initiate with program card . . . now it has got to the point I cant program motor break on, prop free-wheels. Anyone have a fix or is it a bin job, you get what you pay for? CJS

For a 250-300 size heli there would not be a better ESC, at the price it is amazing. Get the programming card, cheap way to set it up properly.

Has potential but the one I got is faulty and awaiting replacement. Loads of function on it and you should definitely get the programming card with it to make life a bit easier

I have used the higher Amp rated YEP's for various airplanes and I like them a lot! This 30Amp version does not have the Acro brake function, so that's why I give it only 4 stars/crowns. YEP's are also a bit harder to set up, but the have a load of options. You want the programming card.

Got two of them. No.1 does nothing at all, No.2 does what it wants. I will definitively NOT install them in a model, just disposed them both to the garbage.
