Is there a chuff input on the AC Commander? I was looking at the manual and didn’t see the provision for it like the Cruise Lite. I am trying install RS3 into a engine with an AC commander. If there isn’t the option for the chuff input on the AC commander, is there a chuff input on the old RS3 board?

There is no chuff input on the AC Commander. For reasons I'll never understand, they added a second antenna connection instead of the chuff connection! 
It's easy to access the chuff input, just solder a wire to pin 17 of the R2LC connector for the chuff connection. It's a switch input to frame ground to generate the chuff. It's the same as the other products that have the chuff input, they simply tie it to pin 17 of the R2LC.
That’s a simple enough solution. Thank you!
Sometimes the simple solutions are the best.
