A couple of years ago I started looking at what it would take to make a quadcopter.  At the time, I only had the limited tools at the Austin hackerspace available to me (which I don’t think even has a space anymore).  So I shelved the idea since I didn’t see a time effective way to make any of the components.  Fast forward to a few months ago when I joined the TechShop in Austin.  Now I have no excuses to not make a custom Quadrotor.
