I want to buy an ardupilot to fit it in my easy glider.

The weather where I live is dusty almost 10-8 months along the year. Also the temperature is very hot during summer time.

I am concerned about how well the ardupilot will preform in this type of weather. (The horizon isn't clear)

Should I go with ardupilot or uavdevboard? Or should I wait for ardupilot mega?

I should say that I've never worked on an autopilot before.

Any suggestions or comments are greatly appreciated.
