Just an update.
New pro camera/gimble came today so I hooked it up and upgraded to 1.7.0060.
Did a compass calibration, zip tied the marco polo tracker to its leg then when for brisk 27460 ft flight.
I have to say the fpv feed is a lot more crisp/clear than the 2.7k camera while using the Samsung TabS 2 9.7". Well worth the extra for the new camera.
Modded the GL300B controller with the hdmi module, so now waiting anxiously for my new headplay goggles to arrive.
