If your charger looks like this one (specs-wise) it should. This is the Intelli V-2, the latest version, V-3, has more options and a lit display (who charges in the dark, I wonder...)

I'm not sure changing to NiMh is absolutely nessecary though, the NiMhs deliver the best performance when used immedeately after being charged (hot< 45degrees C), this applies most to speed boats.
You can't charge them the day before and run hem cold the next day, without damaging the cells.

With NiCads, you can.
