Russell Sutton's nine-cylinder radial engine LIVES!
The big beastie idles at around 600 rpm, and our favorite mad engine builder has rigged up a clever disc-brake load generator to give the radial something to work against. Pushing against the load, the radial evens out into a delicious thrum. Sutton is currently working on a three-blade prop for his design as he works toward building what will be the world's coolest air boat. Check out the lengthy video for yourself below. The fun gets started around the four-minute mark.
