Customer Reviews

Good company but possibly a bad batch of OPTO ESC's.. Review by Paul R Kunze
I ordeded 3 of the OPTO ESC's. One fried while running for 10 ten seconds. The other two were very hot. (I also had a Greyson 200A BEC as the 4th ESC that remained cool.)

I emailed for technical support. The response was quick and suggested the timing was wrong. I put the first remaining OPTO esc in programming mode and it fried before I could finish programming. I mailed all three OPTO's back and ordered 3 BEC ESC's. I'm waiting to see if I'll receive any credit for returned OPTO's.

I think I received part of a bad batch but I have no way to guarantee that. I wouldn't hesitate to order from Greyson Hobby but I will stay away from the OPTO's for now. (Posted on 12/7/2017)
