I found this website with a Antenna Tracker for RC flying. They say it will be ready in April.
- Essential companion to the EzOSD
- Uses real-time telemetry from the OSD to keep an antenna pointed at a model.
- Two axis guidance, using standard pan/tilt mounts.
- Greatly increases range for CE-compliant European video gear.
No sir, I ordered ONLY the EzOSD. The tracker is still a month or two away from public release, from what I've heard. Unless you are planing on doing some modification, though, you'll need the EzOSD for the tracker to function correctly.
