If you could clarify for what you want to use you want to use a pwm line for, it would be helpful, because as is, I think some posters might be confused as to what you're asking. On the RC, there is a bank of pwm pins and a bank or relay pins, so the two don't need to overlap. Hope this helps (see the below .pdf on the usfirst site and examine the RC)
