E-book: "Build Your Own In-Flight Adjustable Propeller"

  Paid e-book with a license for one person. The book will guide you through the production of adjustable two-bladed and three-bladed propellers, as I have produced or converted them. You will receive manufacturing drawings and procedures for the parts so that you can safely operate these propellers. You can choose over 30 blades from three propeller manufacturers and select either left-hand or right-hand rotation and different diameters. The propellers have been tested for a power transfer of 140HP.

The adjustable propeller that I have converted and redesigned and tested is already in regular use. It is a three-bladed propeller with a diameter of up to 2080mm and a weight of up to 10.5kg, without the spinner and backplate. The propeller blades are made of carbon fiber with a stainless steel leading edge and can be adjusted within a range of up to 20 degrees. I am currently working on a reverse pitch application for water planes.

Some pilots, but rather those who become aircraft builders over time, will understand that only a comprehensive knowledge of the aircraft as a whole - that is, the aircraft structure, engine, and propeller, along with the landing gear and lift mechanisms, and the necessary response of the aircraft's control elements - will make it a proper unit for the intended use. Only then can you achieve far better results than aircraft manufacturers who produce aircraft with many limitations and mostly for the average pilot!

In the book, you will learn how to make your own adjustable propeller in-flight, or how to convert existing propellers and available propeller blades from around the world for your desired purpose. You will learn how to modify the aircraft to suspend a bigger propeller of a larger diameter and I will guide you through changes in CG and propeller reaction and gyroscopic moments and how to limit them.

The book is intended for advanced aircraft builders and those who want to fly faster, higher, and cheaper from shorter surfaces and also land on them thanks to the propeller. With the in-flight adjustable propeller and the book "Make your own in-flight adjustable propeller," you can modify almost any advanced ultralight or experimental aircraft for short takeoff and landing, and also fly at very high cruising speeds, just as I have done.

The price has not yet been determined, and I am working on the book.
