My Parrot Mambo won't drive forwards or backwards or any direction. It will only take off, flip, and land.
I connect to it's wifi connection and try to run the demoDirectFlight.py as part of the pyparrot module, and it will only go up, flip, and land again.
The solution was to keep the controller turned off when connecting over wifi and running the script. I guess the controller overrides any control over everything except taking off, landing, and flipping.
