Okay, you've convinced me on the redundant system on my larger planes and LiPo's are just to spooky due to the hazards. I have a couple for EP airplanes and just don't trust them due to the potential hazards. Now for the next question... can I use my NiCD charger to charge NiMH or do I have to by a new one(s)? I've seen quotted charge rates for NiMh from 10C to 1C. I have an older ACE RC muticharger and I believe that it operates at 10C but I have to verify.

Thanks
