So far so good. With any YEP or RotorStar esc you need the program card so get it. I'm using this on a Freewing 80mm F-86 with the FW 12b inrunner setup and while I've yet to fly her I've done hours of testing, a good deal so with the parameters in the esc. Being able to fine tune the timing is usually left for more high end speed controllers but you have that option with this one. Also you get a whopping 12A selectable SBEC, another killer feature. I'm using 2 other YEP controllers in other edfs and I'm able to do the same. I'm almost positive this is exactly the same as the YEP line of esc's offered by HK which makes me wonder why 2 of the same. Seems a little redundant but not to worry this one definitely works with the card and I have run her up all the way to 90 amps and she doesn't even get warm. I do have it placed in an optimal place to get as much cooling as possible and I also removed the label and cut away the heat shrink to expose the nice finned heat sink. 1 negative IMO is the extra servo cable. I had to find a place to put it and then secure it so it won't get sacked into the fan. Not a biggie but for my application not needed but I'm sure there are many occasions when it comes in quite handy. So far best esc I own.

I bought 2 of these ESCs. Programming it via the dedicated built-in programming lead, does NOT work!!! I have to do it using the throttle lead! Using it on continuous 75A seems to be OK so far. But now I'm gonna use it for 110A continuous driving a JP90mm EDF, installed on my HSD Viper 90. What worries me is, the power wire size is only 12AWG! I came to think, are these ESCs really meant for 120A??? For efficiency reason, I replaced the wires with 10AWG. We will see if it ends up burning my EPO Jet, like what happened here:

If that ever happens to me, not only I will ask for my money back for both ESCs but also for my HSD Jet replacement! Hopefully it will never happen to me!

Preis/Leistung sehr gut . Ich benutze den Regler fr einen sehr hoch drehenden 90er Impeller an 6S 0nd 83Amp. , feine saubere Regelung und Regler bleibt auch ohne Khlung cool . Sehr gute , einfache Programmierung mit YGE-Prog.Card. Sehr zu empfehlen.
