Since there was some mention of this bird in the engine section, I thought I'd post a few shots so people could get an idea of the size.
The approximate numbers are: wingspan 77”, stabilizer span 40”, length 66”, rudder height 19”. For size comparison, I photographed it with a Brodak Nobler.

Weight is around 125 ounces!

(Check the tire deformation in the picture)
Power? At this point it has an OS .61 but I'm thinking about a SAITO .91 or something along those lines.
The Sweeper had been in storage for around 15 years. I resurrected it and we flew it at the Brodak Fly-In a few years back.
Note something interesting - there is a protrusion just aft of the exhaust cutout. Apparently, it once had some sort of internal exhaust system that exited at the rear.
