From now until December 31st, BigRedBee is offering $10 off the "BeeLine package deal".
For just $85 (plus shipping), you get a BeeLine transmitter, integrated lithium polymer battery, single cell lithium poly battery charger, and serial interface adapter.
While you're browsing the BigRedBee website, make sure to take a look at the BeeLine GPS. While not available until early next year, it's a great way to locate those hard-to-find-rockets!
