A WW1 biplane with a 54'' wingspan weighing 15 lbs.? That should be interesting, and not in a good way.
I thought the same thing... It's the weight of a much bigger plane... (Stall speed 74 mph, max speed 76 mph)
I would make video the maiden just in case. On the other hand, no matter what the weight, the CG hast to be in the correct place, otherwise, it will be tail heavy and short lived...
