1,000 mph bloodhound
This news is a couple days old, but its the coolest thing I've seen in a while. The Brits are looking to extend their land speed record to 1000 mph according to this article. This isnt r/c related, but a lot of guys that are doing this high speed r/c stuff are influenced heavily from full size cars. Nic Case's record breaking Schumacher streamliner is based on a full size JCB diesel streamliner. So you can easily see the influence that full size cars have on the r/c racing community.
