Merry Christmas everyone, I certainly seem to have stirred things up. I am not confusing them with something else and I stand by every word. Try flying seven days a week and flying a battery until it is flat several times a day. Peter, maybe you remember when I told you I could do an outside loop with a helicopter and you nearly needed a change of underwear when I did it. Percy, I didn't say they were unreliable in transmitters.

NiMH batteries are really only useful for transmitters.They can be used as receiver packs but treat them with care. If you use them as an electric power pack, be aware that they have a narrow temperature 'window' and they don't work well until they are warm. In the days before Li-Po's we used them for mini helicopters and used to charge them at 1C. Life varied from as little as 4-5 cycles, They suffer from extreme memory effects. DON'T cycle them. In a nutshell, they are unreliable.
