I managed to get along; the 5" turbo-electric loco was indeed amazing.
What my discussions with the aforementioned "highly knowledgable people" did confirm was the relative inefficiency of these small turbine powerplants & whilst the idea of using these model motors to create a 4-engined 152 does seem strangely appealing, the endurance would be measured in minutes rather than hours.
