I'm casting around for ways to improve the erratic behavior I'm getting on GS flights, with extensive toilet-bowling at waypoints and off-track flights. Does anyone know what the ideal arrangement is for the air-end antennas? How important is their positioning and is there anything that might adversely affect the antennas, such as an fpv transmitter? Then again, once the mission has been uploaded to the air-end, I presume the antennas only serve to make the connection back to the iPad or laptop, to display the position of the quad. Correct? I'm rather discouraged -- my high hopes for using the GS to survey streams and wetlands are getting lower with every flight.
