this happened with the suddenness of a broken shoelace. the aero car tumbled off the table, broke the prop, bent the front truck and broke the motor mount off the chassis. installed a new prop, fortunately these propellers are virtually disposable, a few dollars each for the plastic props. i am sure they are frequently broken on model planes.

Ben;

The motor is not mounted pointing straight ahead. Is that a result of the accident. The angle, would put added force on the car in the direction of the derailment, other than centrifugal.

Dan

the motor is angled approximately 7 degrees above parallel to the track to provide down force on the wheels. taken from the original rail zeppelin.

Make another one with the propeller mounted higher, and make it a puller instead of a pusher. Also angle the motor down slightly to give added downward pressure Less likely to derail.

Dan

mounting the motor higher running as a tractor and it will derail in a curve at almost any speed. already did that experiment.
