Lou, a good prop for the Norvel that's not represented is the Cox "rubber ducky" 5x3. The APC 5.7x3 is probably going to be what your looking for, but it's not nearly as durable as the 5x3.
Tim, I ain't worried. We gotta show these boys how to build light! Lou, at almost 19oz you shoulda be yelling OINK on a hard launch.
Billy's is pretty close to what you should see. All of them look like they mean business! I expect my CWUS (combat wing ulmer style) to be less than 12oz when complete and ready to fly. I'll be flying with a Surestart reed valve and an APC 5.7x3.
