Corona however, did not implement the use of the ES02 chip in the FHSS versions even though it's fitted on the board. Testing showed if you removed the right antenna the system died...
They may use it on the Corona DSSS version, but I was not involved in any pre-production testing on that one.

I'll be very pleased if FrSky do switch antennas on high error rate.

Cheers,
