I have the YEP 45A ESC on my Warp. This is a great ESC. The program card is super simple. It has a GOV that actually works. Very good slow start. Active free wheel. And all for $25.
For those of you that look down on Chinese, HK copies. This is a copy of a YGE ESC. One of the top brands for ESC. I have spoken to someone that has both the copy YEP and the original YGE, and he cannot see any difference in circuitry or in flying.
The only difference is the firmware. The YEP has the V1 firmware and you cannot upgrade it using the YGE firmware.
I will do a write up on it, once i have flown it this week end.
