X2 on Truckracer's last few comments.
I only wish I had found out about A123's earlier, when I was just getting back into the hobby (a few years ago) and looking to replace some really old NiCads. I could have saved myself a couple of pretty nice planes by ignoring advice to go NiMh at the time. Another lesson in bad advice is worse than none. Cost me a lot of time and money to recover from that advice, no matter how well intentioned it was. -Al
