I replaced an ESC on my Vision Plus today as the lights were not working on that ESC. Now I'm getting a series of four red flashes with beeps from the new ESC when powering-up. Also noticed a very slight twitch in the motor during power-up kind of like a thoroughbred wanting out of the starting gate. The bird flies and hovers fine and shows the normal red lights on the front during flight which is where the new ESC is located. This is the ESC that I installed: http://www.ebay.com/itm/DJI-Phantom...ol-/351081274008?ssPageName=ADME:L:OC:US:1120 I'm wondering if there was a recent update to the ESC's that displays the power-up sequence mentioned above. Anyone with a fairly recent new Vision Plus that's seeing the four red flashes with beeps? Thanks for any help or tips.
