Aeros and ASI Calibration

All is going well and I'm now getting into aerobatics which is what the Twister is designed for.

I've entered into the Club competition this year and have started to put the sequence together already. Although it is full of errors and my G-tolerance sucks at the moment. Anyway lots of time to get those things right as the comp is not until the end of May.

I expect to come last in the comp as the others all fly Extra 300 and 200 aircraft - which is a bit ridiculous as this is supposed to be for newcomers to the sport. Anyway it is a good disciplined way to get better at aeros rather than just going up and mucking about.

A short video of some aeros here (with a little cloud play at the end): https://youtu.be/oS4TldFLphM

I also did a calibration of the ASI's to see how accurate they were. See the results below. I probably did not fly such an accurate sequence here as the altitude varied and the day was not exactly calm. Even so in the mid speed range it is quite accurate. The Dynon and Winter both agree with each other to within a knot most of the time - until either extreme of the speed range when they get about 3 knots out.
