One of the more impressive models on display in Toledo was Jim Weigle's MIoscale, 21-foot-long Concorde. With an 8-foot wingspan, the 225-pound jet is powered by four AMT Olympus AT 450 turbines-each of which produces nearly 50 pounds of thrust! Jim designed the jet using a scale plastic model, then had fiberglass molds made to spec. With only the radio equipment and some hardware to install, the jet should be ready to fly soon; we'll keep you posted.

I can add some clarity on the construction. The molds and first fiberglass fuse and wings were built by JohnCarlson out of the Minneapolis area. At Superman Rally back in maybe 1999 or so the stuff was delivered to AMT. The body was made of fibergladd and I think that Weigle installed an aluminum spar system. The body and wings were very light (I actually helped John deliver these parts and carried them across the field), and I can imagine the need to hold the structure for the turbines was machined structure which added weight.
