Helicopter construction tips wanted

AI Thread Summary
Building a helicopter is a complex and potentially dangerous endeavor, with significant concerns raised about safety and regulatory compliance. The discussion highlights the importance of understanding the technical aspects, such as propeller blade pitch calculations, but emphasizes that constructing a helicopter without proper expertise is ill-advised. Participants express skepticism about the feasibility and safety of the project, particularly given the age of the original poster. The thread ultimately concludes with a warning against pursuing this activity, suggesting that purchasing a kit or pre-built helicopter is a safer alternative. Engaging in such a project without adequate knowledge and certification poses serious risks.

So my friend and I are building a helicopter this summer. I was designing the propeller blades and could not figure out what angle a stood for in the pitch equation
a=arctan(P/2pi*r)
P=tan(a)2pi*r)
Also if anyone has any tips or has done this, any advice would be extremely helpful!
Thanks!

I hate to [STRIKE]pis[/STRIKE]... uh, er... rain on your parade, but the general rule is:
If you build a helicopter, do not get in it. It's different if you're terminal and your wife has an awesome insurance policy on you, but otherwise buy a kit or a pre-built machine. I know how they work, and I know how to fly one, and I'm something of a genius, but I would not dream of designing and building my own chopper. Also, there's a pretty good chance that you couldn't get it certified for airworthiness by your national regulatory agency.

Jeez, I hope this is a joke...
 
that would be a negative

Thread closed as a dangerous activity. If you can convince me via PM that you are truly capable of doing this safely, I may re-open the thread.
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
