FYI on the rotoflex couplings, they were also used in Formula 1 cars
(especially Lotus) from the very early '60's. Eventually, CV joints
replaced them in this and other racing applications.
I suspect the problem is "cheap replacement parts". None of our motors, not
even a stock-ish V6, should put out enough torque to tear up a rotoflex. I
bought the QH (ugh?) type and have had no problems with 12k of street
driving and 3 vintage race weekends.
Stronger versions yet are available from race shops
