These are examples of repairing the chassis if it cracks near the motor pod. The most important patch is the upper patch; bend a large paper clip into an M shape that snakes around the reinforcing bumps at the end of the chassis. Superglue into place, being careful not to get the wire over the pod mounting holes. Remove pod screws while you are doing this so that superglue does not get into the holes or the POD hardware. For reinforcement (originally of a styrene patch that did not last) I also put a paper clip on the bottom of the chassis. Obviously you need to double-triple-dog check that the wire cannot contact the track braid; I flattened mine carefully with a Dremel sanding drum. Some paint over the wire may add a little more protection, but I found mine to clear the braid comfortably so I did not do that..yet
