Default Can I use NiMH batteries........

....for my HPI Roto Start system?? It doesn't say so in the manual to use or not use it. Also, is it advisable to use NiMH to use for radio and receiver batter y?? I've read somewhere that NiMH can't be used on certain applications.

It's fine to use NIMH in all three. Usually the NiMH have a higher mah capacity which makes them more desireable to use.

Be careful using Ni-MH's in your transmitter..Nickel-based cells only have 1.2 volts per cell, as opposed to 1.5 for alkalines. The voltage in your radio will drop when you use Ni-MH's, regardless of how well they are charged.

For the same reason, you must run 5 cells in your receiver pack to get 6.0 volts like you do from 4 alkalines; that's why receiver packs are 5 2/3 A cells instead of 4 AA's.

Thanks for the replies guys. Yeah, the radio and receiver that came with my HPI Nitro MT2 uses alkaline, so I take the NiMH will be fine!!
