All that can, should do a special test flight, with their Sparks, today. This will test something important.
Measure an accurate line 10 foot in length. Now pilot your Spark, starting at the exact tip of the line and fly an exact circle over the tip of the other end of the line, returning to the starting point. Do this 10 times. Now look at your flight record and find out how far you flew. Is it 314.159265358979 feet?
What did this test, Besides the accuracy of your flight data? It tested your appreciation of Math. Happy Pi day everyone :-)
