So I bought these cheap Chinese brushed ESCs from eBay: https://www.ebay.com.au/itm/1pcs-Sy...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 Problem is they came with no documentation, and I can't figure them out.... So far I've determined that they can power my receiver just fine, and that if I switch the little switch on the board, the LED changes from solid to flickering really fast. That's about all I've worked out. I get no response at all whether I switch it on with full, half or zero throttle. I've tried inverting the channel. I just can't get any sort of response from them. Anyone used these little red ESCs before? Anyone got any documentation for them?
