Why do you need a Bad Elf? Doesn't your Stratux have a GPS? Make sure your iPad is connected to your Stratux WIFI. Then, open iFly and click Menu - About - Connected Devices - Select Wireless Device - Next Page - Stratux/Flightbox. Finally, make sure you clicked Map Mode - Traffic.
Is your Stratux dual channel so that it can pick up both 978 and 1090 traffic? You can usually pick up 1090 traffic on the ground. You usually need to be in the air receiving a ground station to pick up 978 traffic.
