RE: picking a TX has become mind boggling !!
Don't forget Jim Drew's 2.4 system- XPS. I see the module and receiver price for a 9C has dropped from $250 to $200. In fact, most of his prices across the board have dropped. Just remember that converting a 9C to 2.4 will leave you with an 8 channel radio- you only get the 9th channel when using PCM. Oh yeah, the 2.4 gHz 6EX is a VERY basic transmitter. I'm only using it as a stopgap measure until the radio I really want is available. I feel sooo limited using the 6EX although I prefer Futaba's 2.4 over Spektrum's.
