Bombout from Mt Bakewell showing my XCTrack Screen (Warning Bad Language) 

XCTrack is an Awesome App for Android that acts as a flight computer. It does everything you could want. Here it is mostly in the thermal screen that I have customised. The arrow in the bottom corner shows the computed wind direction. I was expecting a SW but it seemed to be more NE and that was probably why i could not work out the drift. I should have paid more attention to XCtrack.
