It is my belief that this is identical to the Hobbywing version. There is a Turnigy V2 of this ESC but the back plate is a different shape . The ESC on sale is identical to the Hobbywing. Printing and identification labels have been obscured due to the fixing method in the airframe. The ESC was part of a 10S configuration aircraft that was not flown. Programming card for this device appears to be still available. The ESC has been tested with a 50 65 motor and 5S battery. All the right noises and operation. A high load test with prop has not been performed.
