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.***

Throttle response is not linear!!! - When we slowly increase the throttle, at about of 75% its position, RPM drastically decrease and from this point are regulated up again... For heli it is dramatic.

That was "FreeWheel - On" blame.

It is in the file section as a PDF file, I have tested it and it works just fine.

The YEP and YGE ESC`s should be the same. Try this programming manual for programming with transmitter (without programming card)

I bought 4 this ESC 30A for multicopter size 450. But not sure how to correctly set up. One or some of these four sometimes flash red and some times sound error when I test my 450 copter. Please help me if anyone experienced to set up this ESC for multicopter 450. Thanks

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.
