There are really two reasons why an LVC won't work well on NiMH:

1) All current LVC circuits assume lithium cell voltages, which is 4.2v/cell peaked, 3.7v/cell nom, and ~3v/cell cutoff. Since NiMHs are 1.2v/cell nom, you'd have to always use a multiple of 3 cells (3 NiMH cells roughly equals 1 Li cell).

2) NiMH drop voltage more under load. During heavy starts, the voltage may drop below LVC threshold quite a bit. Of course, the amount of v drop depends on the setup; 10th scale 2WD is a lot easier on batteries than 8th scale truggy/MT.
