Hi Bruce,
Damn! .... That creates a bit of a problem. I was looking at upgrading to 2.4Ghz from 72Mhz FM for my quadrotor machines.
http://homepages.paradise.net.nz/jameskea/ I currently tap off the raw PPM serial stream and feed this single output to a micro's input capture I/O pin for processing.
The idea was to re-serialise, for want of a better word, the 2.4Ghz Rx outputs via the standard 'alternate channel' 'OR' diodes/BC548 arrangement. This only works of course if data is sequential.
I was looking at using either FrSky module or a Futaba FASST system.
