Guys ... how about the World Models Super Frontier Senior? Its huge for a 60 sized plane with tons of wing, I am pretty sure it cna carry a 2lbs payload. Also you can try the Super Stunt 60, that is huge too. If you are not too concerned about windy conditions then the Clancy Lazy Bee 40 is another plane you can work with. That has about a 6' wingspan and its like a big elongated coffee table.

For the abovementioned planes its got a wide enough fuse for EP, get something like an AXI 4120 on a 4S/5S set up. One thing though, flying at 50 mph bikers will not be easy when the plane is laden with a 2 lbs payload, again I say this on the basis that you want a managable sized plane and not a 12' Telemaster.
