The second design would use an R/C servo to move two permanent
magnets. There are no models workingâ" or non-working.
If I tried to develop a model, it would be based on the first design,
using damper plates to control heat distribution to the ends of a
reversible duplex coil engine. the tricky part would be in finding a
heat source that would keep both ends operating when the damper plates
were centered and provide quick responses when the plates were tilted
in either direction.
Developing a model based on the second design would be more difficult
because of all the interactive variable factors that would have to
come together to make it workâ" somewhat like opening a can of worms
and expecting them to crawl in the same direction as ranks and files
the first time out.
