frames per second (7 millisecond period).<BR>3) Therefore I assumed the transmitter always transmitted at the higher rate<BR>and the receiver decoder decided what data to use.<BR><BR>Now I'm not sure of anything. The transmitted rep rate and the receiver<BR>output rep rate to the servos may be completely different. The transmitted<BR>rep rate might be 300 frames per second or 50 and they may save all the data<BR>in the receiver and send it to the servos every 7 msec (some old data?) in<BR>some receivers and every 15 or 20 msec in others. I would like to think the<BR>S.bus would send new data to the servos every 3 msec (PWM servos probably<BR>couldn't handle that but servos with a digital interface could). It would<BR>be nice to talk to someone who knew how it all worked.<BR><BR>I suspect the S.bus decoder puts out a pulse every 15 msec but I could be<BR>wrong. In any case I think we know the ESCs will work with 15
msecs so they<BR>should work with the 7008SB as is. I can't see how the receiver could be<BR>causing the problem as it was described. What does Futaba say Robert?<BR><BR>Jim O<BR><BR><BR>On Mar 19, 2012, at 12:55 PM, John Gayer wrote:<BR><BR>> Jim,<BR>> I'm confused. Isn't the HighSpeed mode related to a higher frame(rep)<BR>rate?
