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 have a quick question about these ESC's. I have a multirotor with motors that do not like the 400 Hz refresh rates when used on 4 cell. Does this ESC have standard low refresh rates or is this in the 400 Hz range?
Thank you for reading
Works like a charm in my AXN Floater. I have set it at 8khz PWM, auto timing, freewheeling off and governor off. Startup power is high. Motor does get warmer than it did with the stock AXN ESC, but I attribute that to my new found confidence with the performance. ESC itself never even warms, but I have mounted it externally for cooling and isolation from other electronics in case the worst happens. I'm going to be buying these exclusively from now on.
I'm using this on an airplane and I got the programming card to get this setup the way I'd need it to be. However, I'm having a repeating issue: Sometimes if the motor gets stuck or stopped (nose over on takeoff/landing as an example), it will then sit there and continuously beep at me when idle. I can give it throttle and it works just fine, but and the beeps stop. However, whenever I cut the throttle and have it sitting idle, it will continue to beep. I've even pulled the batteries, but as soon as I plug it back in, it will do it again.
This ESC has been nothing but a PITA since I got it. Any help would be grateful.
Here's a video showing the motor sputtering at start up. It sometimes does this, then stops and begins beeping at me continuously. I couldn't capture the beeping on camera, but you can see the sputtering on startup at the beginning of this www.link
Hi Scott sounds like the esc thinks you have some throttle on from a stopped position and the beeping is the alarm. Try turning the throttle trim on your transmitter down to its lowest position. If not this it could be the soft start you have selected,for instance if you have selected heli start. This would also explain the sputter you talk about. Try selecting a harder start option. Hope this helps
OK scott first i need to know the sequence of beeps.When i forst used this ESC i kept getting 6 beeps meaning failed startup.After trial and error i found i had the wrong startup power setting and the PWM FQ was wrong also.Change your startup power from Auto to 2%
Don't worry about it guys. I've already returned both ESCs and the programming card and gotten a refund.
But just so you know, I literally tried EVERY combination of startup power, frequency, and timing. Sometimes it might work, but after a day or two I'd try it again and the error repeats. Frankly, the options this ESC offers is just too far and beyond whatever I could need.
Yes in the hard left position on the Servo Driver
They don't work when attached to a Receiver either
Testing was done one at a time, over and over. They power up the receiver so they are getting battery power, Servos work on receiver while testing the ESC
These are suppose to be for multi rotor craft.
I guess I could put plugs on the other 2 that I bought as spares and try them. But this is so strange???
I have been in RC for 30 years, boats, cars, planes and now multi rotors. I am flying a tricopter with a KK2 board, love it. Decided to try a Quad copter and ordered some SK motors and some YEP 30A ESCs. I set up 4 of the ESCs for the Quad and none of them work, nothing. The BEC powers up the receiver but that is it. No beeps nothing on any of the ESC. I tested them with a servo driver and with a receiver and servos the servos work, no movement from the motors and not a sound. The motors work just fine with a Turnigy Plush or other ESC.
I ordered the program card.
Any one have an Idea?
That is really strange. It is very unlikely that all 4 are broken. Mine were working out of the box. No programming was needed. Are you absolutely sure that you started them in the -100% position? I guess the servo tester is able to provide even -120%. Did you parallel connect all BECs or did you use just one on the quad setup? Some BECs do not like other voltage sources in parallel. However, my impression was that the YEP ESC allows parallel use of BECs.
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.
