Hi Ralph,

No, the 9Z cannot use the Polyswitch, as the 9Z's battery is self contained. What you are wanting is the Battery Discharge Connector, HSP78050, which you can purchase through your local hobby store. This connects to the battery itself and allows you to cycle the battery outside of the transmitter.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

Sincerely,
Krysta
Lead Futaba Customer Service and Programming Technician
