Hobbyking YEP 45A (2~6S) SBEC Brushless Speed Controller

Hobbyking YEP 45A (2~6S) 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! 

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 
• 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.***

I have the V2 with 2 cables - one with the ferrite ring and one without. I just want to confirm that except when using the programming card I am to run with *both* cables connected to my receiver. The "ferrite" to 'throttle' and the other to 'batt'. Is this because the single cable cannot carry the current needed? Thank you!

Hey Bill_A nooo..the second wire is only for the Programmcard... so u dont have always to unplug the throttle wire if u program something Cheers

Thank you. There is a V2 listing for the YEP 45A which was added since I purchased this (or I simply asked a question under the wrong one). It shows both wires. www.link If the url is stripped is Product ID 52340. I wish they had put on a female connecter close to the board so the cable could be removed. I'm storing it under the battery tray making a little harder to get to.

Hi Mr_pibb and hoybb. Please do not make other people confuse by put comment for other product on this product. There is nothing to do with this product if others product are not reliable.

Nice, Hobbyking deletet my previous warning about this Product. That shows how much you can rely on the comments here. Anyhow, here`s my comment again: No, I figured it out. It is a RPM Signal Cable (I got a V2 of this ESC) I absolutely do not recommend getting this ESC, especially If you get the V2. Like in other comments, the BEC is terrible, it will fry your other RC componentes! The Voltage peaks extremely high! (In other comments someone wrote 10V) I tried using it in a heli, but the voltage is so unstable and has so many peaks, servos and gyros won`t stay still... After 2 min my servos started to die. So DO/NOT/ BUY/ THIS THING! Happy deleting Hobbyking Crew!

Also recieved one today. It has 2 Servocabeles attached onto it. one is a bit longer and has a ferrite ring on it. For what is the second cable?
 Graham 31 points
One will be the Throttle Signal cable, and the other will supply the BEC current to the receiver and plugs into the battery terminal [or any spare terminal] on your receiver. If you don't have a spare terminal on your receiver you could use a Y lead to combine them, It shouldn't be a problem.

I stand corrected. It looks like Ill be using a separate BEC when I begin my build.

Bought this to use in Bixler with the BEC to power everything. The switching BEC is not good. It blow the APM controller and some 10 of the types HKSCM12-5, HKSCM12-6 and HK-15178B before I nailed it down. Average voltage is around 5.5V. But looking in the oscilloscope there is a short voltage spike of almost 10V. Guess that is part of the switching BEC circuit. But it kills servos. So beware.

Sorry, it was actually the YEP 45A V2..

Super Regler - funktioniert in allen Punkten wie er sollte. Enorm gutes Preis - Leisungsverhältnis. Die fehlende Anti - Blitzschaltung fällt bei diesen Stromstärken noch nicht auf. Das wird mein neuer Standardregler - man braucht einfach nichts anderes nehr.

Very good Controler! First I have tested it without gov.
But I had to recognize that it doesn't work with softstart in this mode. The speed change takes several seconds. Flying was neary impssible with that.
I think the softstart doesn't have a switch which turns it off after a certain time. It runs permanently.
But the gov. mode does exactly what I have expected. Real good apadtion of the speed. The power consumption is great.
I can fly longer than with my old ESC. The temp. of the esc is about 36°C after 6 minutes of flying at 85pcnt opening.
That is a real good value for the money!!! I will by a second of it when I build a new heli.

Very good built. The wires to the motor and battery are very long and soft, easy to twist around corners. I also bought the programming card, there is lots of functions and programming is as easy as pushing a button on the program card!
