Hi Nick, Just to be clear, Do you mean you can't have the servo pulse sent to each sevro in series as happens with a regular R/C Rx? I assume if the answer is no you can't, I am sure you have a valid reason not to be able to have the possible 2mS lag from 1 to the next. I will tell you it is the easier way to handle this.

A pointer for you - In the other thread I see you were using the interrupt to control when to update the servo. So I assume it fired every 16-20mS or so. May I suggest you set that up as a 1mS timer. Then increment a counter in the ISR and leave. In your main, check if the timer = 16 (or whatever your frame rate need to be) then update the servos.
