This is a not so good copy of the genuine one. It has a huge capacitor back packed on its back side. With this it will hardly fit into a sailors fuselage.

Phantastischer Regler - verwunderlich, dass der "Clone" frher am Markt war als das angebliche Original. Wer kopiert da von wem?

A strong and small controller, i use it in my Durafly EFX Racer with a NTM Prop Drive Series 35-36A 1800Kv / 875w motor and a apm 7x8 prop. 100A for 10 seconds are no problem.

Hello,

The BEC delivered 17V at first attempt for an expected 7.4v !!
Receiver died but fortunaltelly, the BEC was not connected to my expensive servos and FBL module !
Finally, within the following seconds some components of the ESC "explode".

I have a lot of YEP ESC ant it's the fist witch is faulty... Try a request RMA and waiting for the inital evaluation from HK.

Will update later.

Regards,
Franck

I am using two of these to power 2 x Dr Mad Thrust 68mm 2200Kv fan units in my LX F4J Phantom. Programming is essential and was easy using the programming card. Be sure you hear a "tone" whenever you enter a setting - this means it was saved to the ESC. I screwed this up initially and was getting frustrated that my settings were not having an impact. Despite the separate programming cable, I had to send the main receiver cable to the card, and a jumper cable to the ESC (the jumper is supplied with the card). This permitted programming. Default set-up is for a heli, so I needed to set the start-up speed to "plane fast" to get crisp throttle response - this setting also affects the acceleration throughout the throttle range. My only wish is that we could reverse the rotation direction - I had to do it the "old way" and swap two wires from the motors to the ESCs (not easily accessible in a jet). I also cut the heatsink free of the shrink wrap and pulled the label off for better cooling. I changed out all wires to higher gauge based on the currents - I now concur that the stock wires appear to be undersized. Despite requiring mods, I find these ESCs to be the most reliable out there with highest quality and capacity.
