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!
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/6A Switching BEC • 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) • 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 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: 45A Max Burst Current: 55A for 10 seconds Input Voltage: 2-6 cells li-XX or 6-16 Ni-MH/Ni-Cd battery BEC: 5.5V/6A Switching BEC PWM: 8~16 KHz Max RPM: 240,000rpm for 2 Poles Brushless Motor PCB Size: 50x30mm Weight: 63g (including wires)
Hello need help, i still can fly my heli with this esc but sometime i lost power and have to land immediately, disconnect lipo then plug it back in then it flys ok. and when i plug in my 3s lipo, theres no cell count beep on startup, have tried everything,have programmed it to detect lipo cell auto.
My YEP 45A ESC often produces two beeps in a repeating pattern with a flashing red LED. The heli motor will spin up to about 1/3 speed and that's it.
What does this error code mean? How can I fix it?
2 Beeps and flashing = Low Voltage Alarm.
Move your Gasstick in 100% Position and Power on the esc. After beeping remove the battery without moving the stick. The Error is deleted.
Check your first your battery and then timing / pwm frequency and startup power.
I am also planning to use this ESC on G31. This is my 3rd FBL system after BeastX and ZYX. I do not recall any FBL ask for your ESC freq. Plasticbaldy, could you clarify your answer. Do you mean analog servo or something else.
This feature is handy if you are building a model and the ESC is buried away somewhere and not easily accessible and once everything is installed you can get the motor to run which way you want.Yes,ok you can test this before hand and swap wires if its wrong but it is a feature the ESC has and can be used if you wish.
just to double confirm again i think this esc dun have the motor reversing function from the programme card right?
as mine already use to it reverse the motor by switching black & red wire to get correct direction i want.
I had hardly 5 flights with the esc and today while spooling up everything suddenly turned off . I checked all connections and tested the esc . There is no power output from the esc . Did it get fried ?? I am very sad to experience this
My setup is 3s 2200mah , turnigy sk3 helidrive motor
are ur setup is overheat the ESC? what is the temperature when the ESC was stop working.
it maybe ur setup or may be defect unit.
if it was not ur setup issue, please report to hobbyking support centre. take the video & sent to them. let them invertigate if anything come from ESC, they will replace for you.
hope the info helps..
Even If you would use this ESC with a RC car you wouldn't be able to have like 4 wheel drive or anything fancy just a plain motor because this ESC doesn't deliver that kind of Ampere that you would normally need to run 4 motors in a car or even 2 big motors, it would be too much on the ESC.
Hi I have just fitted & set up with program card, My HK450 Pro is flying smooth but I seem to have lost my upward speed when I push throttle up fast, seems to have very reduced punch of power ,I am running an SK3 helidrive, I have read through what is here but cant seem to get it to do what I need, Im not using Gov but that shouldnt matter plus middle start as slow was wait half hour for something to happen. I have also raise to 24 timing but didnt change much Has someone been through this that can help me. I know is probably something simple
Hi. Perhaps you need to (re-)calibrate your throttle range (start the ESC with 100% throttle on the radio/throttle curve, and then, after the beeps, go back to zero) ? Otherwise you may need to push up your throttle curve in your transmitter. By the way, once it is ok, I recommend the use of the governor store function with this ESC (you will no longer have to think about throttle curves).
sporty you hit the nail on the head. I haven't seen something like this before and I have ESC's from CC, Hobbywing, Scorpion and Align. grmis didn't understand the problem here is my version: This ESC isn't responsive lets say you have %50 throttle and go to 75% by giving more collective it takes a long long time to response and vice versa when you go from %75 to %50. I have the progr. card and tried almost everything. I am sure (maybe not ) that there is somthing that I am missing.
Similar problem. No motor till half throttle. Tried initializing ESC with throttle stick up, waited for recalibrate beeps, closed throttle. Still no motor till half stick. Have I set the timing wrong ? Motor is NTM Prop Drive 28-36 3000KV / 755W.
Ich hatte grosse Probleme beim programmieren. Inzwischen habe ich festgestellt das beim ESC ein Akku eingesteckt werden muss und beim ESC direkt ein Akku angeschlossen werden soll, dann funktioniert es. Motorbremse ist bisschen schwach, sonst alles ok.
Thanks grmis for the information. I tried to link my YEP ESC to CC software and it was not recognized. Also the instructions for the YEP ESC do not seem to have anything about data logging which is a main feature of the CC ICE ESCs. So I wonder what you mean when you say that the YEP has the same firmware as the ICE ESCs??
Ah, Thank you. That makes it clear. This seems like a good ESC.
I do have another question:
The instructions say that you need to calibrate the full throttle range when you are using Helicopter mode with the governor function. I am not clear on how this is done. Do you have to calibrate this one time only or each time a battery is hooked up to the ESC?? Is this done by attaching a battery and advancing the throttle to full and then back to zero????
Turn on your Tx. Move the TH stick to max, trim at mid (0). Connect the ESC to battery, make sure you attach a motor to it. After you hear a beep, lower your TH stick to min. After another beep, you can unplug the battery. You just need to do it once, unless you change your radio gear.
So, if i am choosing between this one and the K-force 40 amp, which is better?,, but i have some questions about this YEP, it says SBEC, Does it has a switching BEC volt or not, i dont see any jumper in the picture,, secondly, where is the heatsink of this ESC,,, finally, what bothers me is they say when signal lost it cut off power, it is supposed to gradually reduce power not cut power off...
This has a very good governor function, and is very efficient. SBEC means that it is a switchmode BEC which is more efficient than a normal (linear) BEC. It can only output 5.5v on the BEC. Power cut is nice at-least for Helicopter. Signal lost is the receiver signal line, not radio signal. I have 2 of these and 1 100A, and very happy with them. Smooth slow startup for helicopter.
the SBEC can be set / switch at programming card which have to purchase www.link ESC themal management really rock..!! i test mine unit hover for 4 minutes using hk2221-8 motor with standard setting. the esc temperature is approximately 45C only.. instead i use original align esc it will up to 65~70C which is quite hot in same fly situation.
so don worry on heat sink on this ESC
So they seem to be the same as YGE, but they are notified 6A bec and YGE has only 3A Can anyone confirm that?

Recieved the helidrive 45a the other day and have managed to get it into my 450 pro, I have to say that the lack of instructions was dissapointing however it is the same as the YGE esc that everyone is referring to in the discussion area and the manual uploaded in the files section is the correct one.
First impressions are that the build quality is excellent and silicone wiring is used for both motor and battery connections.
I purchased the programming card with mine also which made programming the esc much easier, i'd recommend buying it if your considering one of these esc's.
Flight characteristics are excellent, throttle response is very fast and precise with the governor mode being exceptional. The overall feeling of power gained from using this esc is impressive.
I have only done a few flights with it installed so far but there are no signs of any issues so far.. I will keep you all posted...

overall very nice esc well put together,thought out and looks cool too, most important bit it works great, little heat build up very smooth throttle response and start up silky smooth,im running with a 2215h typhoon and 30c turnigy and it goes hard!

I use this in a hotliner sailplane.Low height of ESC allows it to slip into narorw fuselage.Excellent programming using card.Will by more,very good value for money.

reveiw update: this esc is just awesome, gained an extra couple of minutes flight time over my old trust, runs almost cold even with a few full pitch dumps and startup is sweet, no more smooth start then a bump in power up to go,also the gov mode seems flawless ,to me anyhow! verdict, i bought two of these and id by more in a flash.Cheap doesn,t mean nasty anymore, very happy!
