For the money, these are about the best ESC's available. Beautiful super slow startup for helis, and thereafter very quick to react to throttle inputs. Superb! Running on a 450 with 6S setup.

very nice ESC with the programing wire separate from the signal one. easy to program with the card and seems like a very good quality ESC.

Der Regler ist einfach genial. Der Governor Mode regegelt absolut stabil , auch bei 60pcnt Reglerffnung. und wird nicht warm. Ich fliege den regler in einem Mini Titan E325S seit 80 Flgen ohen die geringsten Probleme . Das BEC ist mehr als ausreichend und stabil. Unbedingt die Programmkarte dazukaufen. !!sonst ist dei Programmierung ein Quler

YEP's ESC's are OK, but NOT this model (V2) I have only YEP's, but this one has a lot of ripple on the 5 V rail ( 1.55 V peak to peak). The peak voltage is very close to 7 volts. I was able to hear the switching noise in the receiver. Not good at all.

I connected mine to a tarot 1700kv motor. I tried every settings of timing but still, the motor bogs. I tried until the ESC burned for no reason.

An up date.
ESC is been working fine, no more power fluctuations.
Don't know what to blame but what I did is to calibrate end points and gov store several times with the right timing and PWM frequency for my set up. Fb with 450mx 3400.
Not sure if this had something to do with the servos twitching, don't think so.
But ESC is doing what it suppose to do, happy with it.

I also have problems
When connecting to my receiver you could hear a small beep from the receiver again.
my voltmeter gave 6 volts.
when I got my motor connected and slowly brought up to speed this was stuttering runs.
Also the servo's stuttering start running back and forth.
After full throttle there was smoke coming from the esc.
Direct the batt disconnected no idea if it is faulty, but I'm done.

I installed the yep 45a esc v2 on a trec 450l dominator 6s with kst215mg on cyclic and kst515mg on the tail. Using a Futaba CGY750 flybarless unit with S-Bus receiver. The yep 45a v2 works great. Love the governor store function.

Received my yep 45a esc v2 with the program card today and installed it on my trex 450l dominator. I got 5 flights on it and it works great. I have kst215mg servos on cyclic and align ds525mg on the tail. Governor store also works great.

same problem, BEC output is 5.85V with peaks over 6.8V, all servos twitch and movement isnt smooth. Same servos with Plush 30A work perfect. So I can not recommend to buy.
