Check the listing for details. Headset Controller Cradle for Lightspeed Zulu and Sierra. Condition: New. Listed at 18.50 USD. Cradle to mount the Lightspeed Zulu 3 or Sierra headset controller to a surface. The back is flat. Dual Lock fastener strips are provided for attachment. Note: Versions of the Lightspeed Zulu prior to 3 have a soft coating on the controller, which likely will make for an overly tight fit in this cradle. Also available with built-in clips for tubular airframes. See pictures. This listing is for the cradle only; the headset controller is not included. Note: The auxiliary jack on the side of the controller is not accessible when the controller is in the cradle. I made these cradles originally at the request of a local pilot. After a few tweaks to the designs, he reported that he was "well pleased" with the Lightspeed and Bose Cradles mounted in his Comanche. He was happy, I was happy to help, and I thought that was that. Sometime later, on a whim, I put a listing on eBay, thinking other pilots might like these too. Now, after many sales and positive feedback, I'm glad I decided to list them.
