Back at Superman 2002 a guy called Ewald Shuster had an own design model called a Hotspec.
It looked very like a Hotspot, but only about half the size, one piece & weighed about 5 pounds.
He powered it with a tiny homemade turbine called the AT 40. It used 2.2 oz fuel a minute, idled at 60,000rpm & 220,000 at full throttle.
The airframe would be great for the Wren 44 or Simjet 700.
Does anyone know if it is in production?

Regards
