Today I flew the S800 with a set of Suppo motor 50 Amp. ESC's after DJI announced that they do not have a stock of new ones. It flew great. timing high - 30 Degrees plus all of the usual brake off etc. They were not even warm afterwards.:tennis: I do regard this as a temporary measure until the new stuff arrives. The S800 does fly really great even in high wind and the zen is just superb.:tennis:
