[DMXF]

Spal engineers have come up with a recommended procedure to help that motor live longer (the problem), which is to drill a series of holes around the end plate that allows more air circulation to keep the windings cooler. I haven't heard what the outcome is after the modification, but seem to recall you may get something like 500 hrs out of it, which may be along time on a Cobra given how little many of them are driven.
