Pin 37 on the CYRF IC must be connected to ground. It has been left to float. This is a serious design oversight, causing intermittent operation under certain dynamic conditions. Not an opinion that warrants debate but a fact contained in the design documentation ignored by the Spektrum designer and confirmed by the chip designer, Cypress Semiconductor Technical Support. Unfortunately this is one of many poor design features. This is only a problem on the RX side. The TX module is a commercial off the shelf unit and was designed correctly by that vendor. It is not safe to fly. It is too be expected Spektrum will deny this.
Very Intereeeessssting !!!!!!!! I believe it. You almost have to think these companies think they are the CIA or something !!!! All this cloak and daggar and smoke and mirrors crap !!! Some body at Spectrum knew this full and well and the was overridden by the powers at be saying it's not a problem or the probable failure rate was acceptable !!! Just like the the guy from Morton-Thiokol that knew there would be a failure and tried to stop the launch and was pushed away and they launched any way... And of course we all know what happened...... Makes you wonder !!!
