Re: Tetrix Kit Possibilities
Go to the Vex forum and search out the thread (it existed during last the last North American school year) that talked about trying to do the same thing with Vex parts.
Some of the contributors to that thread knew enough about aeronautics (or knew someone who knew) to make some reasonable assessments of the physics involved.
See if that info (or a resurrection of the conversation using Tetrix specs) can answer your question.
Also consider figuring out how much thrust you can create (by experimenting) using the motors and an appropriate prop. That will get you the bulk of what you need to know about maybe building a quad- or tri-rotor flyer.
If you want to build a true variable pitch helicoptor rotor, I think you are barking up the wrong tree. The Tetrix parts just aren't useful for making the small intricate mechanisms/controls that are the essence of a modern Apache/Chinook helicopter.
