[NSRCA-discussion] Futaba and pattern

[Jay Marshall]

It would be interesting to see the signals to the servos true PCM digital
"words". This technology would require too much R&D for the near future
release but should be active in the labs. 

I have often been tempted to take one of my old TX units and develop my own
microprocessor-controller, just using the modulator and RF unit from the
old. Probably illegal.....

My first thought won't make everyone happy because it will make a lot  
of stuff obsolete but I think it is time to get rid of the analog  
pulse width interface between the receiver and servos.  It is time for  
a high speed computer bus so more information could be transferred at  
a higher rate.  The servo should use a brushless motor and if possible  
a stepper motor that would eliminate the need for a feedback pot.  In  
other words a true digital servo.  It should run with a range of  
voltages (7.2 to 9.0 volts) with no change in performance so no  
voltage regulators would be required.  It should keep working, at a  
noticeably slower rate,  from 7.2 down to 3.6 volts.  It should be  
programmable so servos could be matched exactly at all positions.
