Gordon,

I think you hit the nail on the head. Although I do not completely understand how PCM works at the rf level, mfrs always advertized greater numbers of bits (2048) as being better than fewer (1024). Things could have been better if they had sacrificed 3 or 4 'bits' of resolution to include a specific UUID (universal unique IDentifier) linking one specific Rx to the one specific Tx intended by the pilot. Never understood why they did not go that direction.

Then with Rx failsafe logic designed to require the correct UUID for each frame, the ideal of failsafe 'reducing risks' by instituting preset servo movements and throttle changes (kill the turbine after x.x secs of either the wrong Tx signal or loss of the unique signal) would work better.

Perhaps this is the type of 'less primitive' failsafe design that we would want for the next generation of jet Tx-Rxs. Would some such logic be beneficial in 2.4 MHz systems?
