Manoel,
Be advised that I have been mentoring Team 177 since 1995 (before IFI and the Victor existed). We use between 7 and 11 Victors per robot and some years we build two robots.
We have only failed two Victors in all that time. Both failed due to metal shavings falling into the FET heat sink assemblies (beneath the fan).
If I were you I would re-look at the "dead" Victors during the off season...
My students have reported many "failed" parts that were not failed. Bad or loose PWM connections are the primary electrical reason for these reported "failures". Other "causes" have been mechanical binding of the motor, software and cables/wires going where they shouldn't.
In my humble opinion, the Victor is a highly reliable part.
Regards,
Mike
