With PitchCalc 1.1 for iPhone blade pitch calculation is easy. Just enter the length of your blades and the distance between them when they are folded together. Enter this values into the application and you will get your pitch angle.

This program is very useful in cases where you do not have a flybar, e.g. systems with a flybarless setup. Even if you have still a flybar this application is very nice because you do not need to take a mechanical pitch gauge with you. Just grab your phone and start this application. It has never been easier!
