RE: Buddy Box Trainer Cord Trouble
Bkdavy,
No, Airtronics do not require the battery in them to work as a buddy box. I've got 3 Airtronics buddy boxes (all I fly is Airtronics) and I have the battery and crystals taken out of all of them. It's JR that needs to have the battery in the buddy box to work.
