cheap 5/8 inch square stock at Home Depot

The Aeroquad arms are made from nice, thing 5/8 inch chromed aluminum, and happen to be the cheapie (err, "Best Value") towel bars from the local Big Box hardware store.

I found them in Home Depot.  They're unsurprisingly in the Bathroom Fixtures section.  They come in 18, 24, and 30 inch lengths.  At the Emeryville Home Depot they were $2.50, $3.50, and $4.50 respectively.

They're hidden away in a box on the bottom of the shelf.  Here's what the display looks like. 

Here's the stock number for the 30 inch bar.

Repairing an AeroQuad motor mount

I crashed pretty dramatically over the weekend, and bent a motor mount almost 45 degrees.  It took under a minute to repair to like-new condition.

Interestingly, it was the perfect object lesson, as Chris Anderson (of DIY Drones -- we were at a Bay Area get-together where he was testing some of the new Ardupilot Mega 2.0 features) had just finished telling me that it was more important to make things easily fixable than it was to make things hard to break.

Here's links to the frame, which I'm quite impressed with:
