Jezmo,

Well stated!

Like you I use A123 batteries for flight packs in my newer planes but my NiCd and NIMH batteries are serving extremely well for ignition. I still have quite a fleet of smaller and seldom flown planes that use nickel based batteries and will continue to do so until they die from old age. Yes, these older batteries will probably be replaced with A123s when the time comes but I'm certainly not going to throw out perfectly good batteries just because newer technology has come along. Unless something changes, my transmitters will continue to use Eneloop batteries. In over 40 years of flying RC, I have never had an in flight battery failure.
