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.
Features: • 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.***
Specification: Max Cont Current: 30A Max Burst Current: 35A for 10 seconds Input Voltage: 2-4 cells li-XX or 6-12 Ni-MH/Ni-Cd battery BEC: 5.5V/4A Switching BEC PWM: 8~16 KHz Max RPM: 240,000rpm for 2 Poles Brushless Motor PCB Size: 34x24x9mm Weight: 26g (including wires)
I seriously don't think so, it's a 2700mah 2s zippy compact 35c.
Motor just spins barely and esc cuts off. Cutoff was set to 3.2v/cell.
The program cart shows 3s as a minimum cell count too.
So i recon the discription is wrong.
You are right. The battery should not be the problem. I guess you are either not in the auto cell LiPo mode (may be auto cell LiFe mode). I programmed mine into auto cell LiPo mode and it beeps three times when I connect 3s and two times when I connect 2s. I tried it one minute ago. Actually, my programming card starts at 4s. For 3s and 2s you must make sure that none of the cell number LEDs is on (this means auto cell mode). This can be done by reselecting the LiPo mode.
Tried again today, reset ESC. recharged the 2S lipo put it on the ESC and it beeps 3x ????
It's as stubborn as h.ll, If I take a half charged lipo it works and beeps 2x... Grrr
I'll order another ESC, this is just taking way to long to get sorted.
This means that you are in auto cell mode but it recognizes a full 2S with 8.4V as a valid 3S. Thus, the ESC considers 2.8V (8.4V/3) as a valid cell voltage. You are either in LiFe mode or the voltage reference of the ESC is malfunctioning. Can you please confirm that the programming card shows LiPo? By the way do you actually use the programming card? Is your card really showing 3S. Mine starts at 4s.
It was a Typo, mine is the same as yours. Yes is was set to LiPo. For now I have solved is by setting it to NiMH and adding a volatge sensor to the plane to monitor the voltage, I just orderd a 50A SuperSimple as I allows to be hard set to 2S. (and I have the 40A, 45Aand 120A YEPs actually). Thansk for your help Fireball!
What cutoff voltage per cell did you program? What kind of battery do you use (mAh and C-Rating) and what motor do you use? May be the motors draws that much current, that even the full battery falls below the cutoff limit.
you programmed it into airplane mode, right? I am not sure, but I think it is delivered in heli mode with governor mode turned on. This is most likely not usable for quads. However, I did not try this ESC in a quad myself.
So hatte heute morgen mal die Mö*glichkeit den Heli drauß*en zu testen.
Leider besteht das Problem weiterhin:-(
So wie es mir scheint sind es nicht nur Aussetzer sondern richtige Absteller
Die unterschiedlich lang sind
Hatte die Prog card mit dabei und habe alles mö*gliche ausprobiert leider ohne
Werde am we. Mal die Kabel am Regler und Motor neu verlö*tet vielleicht irgend
Wo ne kalte Lö*tstelle.
An die Loetstellen glaube ich nicht. Welche Servos verwendest Du? Es gibt Typen (z.B. manche Corona digital), die so sehr auf die Betriebsspannung wirken, dass andere Servos zittern. Wenn der Motor aber eine richtige Pause macht, vermute ich langsam ein Problem am Regler. Da hilft vermutlich nur noch Komponentenwechsel.
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.
