A new Brookings Institute report with some worrying recommendations.

William Bishop commented on Chris Anderson's blog post DARPA creating its own DIY Drones--"UAVForge"!!!"The best way for the USG to turn a public open source group into a gov controlled limited access program is to get the guys with the most input, best ideas and skills (ie; HK GCS and many more here) in their deceitful game. Great pretext to…"
Jorge Garcia replied to William Bishop's discussion Motors, Propellers and Batteries"I downloaded Drive Calculator and I think it works pretty decently. It does the job and definitely helps a lot.
