This is probably the cause of #2.

QGroundControl has over 50% MAVLink message loss to the drone.

MAVProxy has around 3% MAVLink message loss to the drone (acceptable).

Using MAVProxy as a proxy for QGroundControl doesn't appear to help.

Checking "High Latency" in the Link Configuration doesn't help.

Using the drone as the access point helps marginally, but doesn't solve problem. Using drone as wifi client is marginally worse.

Newer versions of qgroundcontrol may be doing it better. This process works:

Start qgroundcontrol, but don't start communication.
Start drone, and wait for it to fully boot.
Start communication in in qgroundcontrol. This should download the parameters happily now.

Newer versions of `qgroundcontrol` may be doing it better. This process works: * Start `qgroundcontrol`, but don't start communication. * Start drone, and wait for it to fully boot. * Start communication in in `qgroundcontrol`. This should download the parameters happily now.
