Hi,
Is it possible to add 2 extra channels on a Futaba transmitter 2 channels
"ATTACK" on 27 mhz for boats use ? These 2 extra channels are used for
accessories ,like horn, lights,etc

Thanks

Phil,
I did just that on my 75 mhz attack 2 channel. Check out my website here http://xct.port5.com/channels.html for details. You could use a pic microcontroller to simplify adding the extra pulses to the transmission signal. Also if you look at the receiver it is seperated into two boards. One is the Radio demodulator and the other seperates the pulse train to the servo connectors. If you put an oscilloscope to the pin headers between the boards you can see the servo pulses and demodulate them from here with a microcontroller that will operate your extra channels.
