Campers,
IMHO,
only the Mantis HG Simulator is
The Right Stuff on this list, or even close. The "video" simulators listed are about like saying that student drivers should only be taught to drive in Rolls-Royces and Formula 1 cars, not Fords, but they never get taught to merge or park. Nobody (on the average) can duplicate those elaborate video rigs on ANY practical basis, therefore
no simulators will get used. That non-responding Lookout concept is about as useless as anything that I can imagine, for teaching. You may as well park the glider on the dirt, with a chair under the tail.
I am a strong proponent of responsive, full-glider simulators (Mantis or similar) to be used in real-life HG instruction everywhere.
The best benefit of the HG Simulator is to show (teach) the HG student plainly that the glider
DOES respond well to proper control inputs, which is
not a realistic expectation without a full glider to do the responding. Expecting the student to imagine what they have never seen (a glider responding to controls), near the ground, is just asking too much of any new pilot.
All IHMO, of course.
