Optimum thermalling speed display
How about a bank angle read out on the new Butterfly vario so the guys that think they are flying a 45 degree bank can see they are really only banked 20 degrees? Not sure I need a speed to fly, usually it is as slow as the glider will fly well. Any slower it will mush or be slow on the controls, any faster and I am flying too big of circles. Too many different types of thermals for one number.
