Bad news for future MM users.

[NovakTwo]

Novak is "notorious" for under-specing speed controls. But, you can see what's happened to Castle. They spec the MM for 3s lipos and many users figure that 4s or 5s lipos should be OK.

The 4s or 5s lipo info becomes conventional wisdom out here in R/C forum-land. Then users believe that MM's damaged from over-voltage should be replaced "for free." I have seen comments in various fora where a racer will admit to using an esc waaay out of spec but still think it should be covered by the warranty.

A vicious cycle. Often the factory can't really tell what causes the damage, so the customer is given the benefit of the doubt.
