I really find it hard to believe that the spikes are something that would affect the receiver. Over in Japan YS and Futaba work very closely with each other because of Naruke. The Japanese team are running the CDI directly into the receiver. I would think if this was a serious problem they wouldn't be doing it as closely as they work with each other.

I did also confirm today that the ignition is designed to be run from 4.8-6V. A non regulated 5 cell NiCD or NiMH will work, but nothing any higher than that. They do NOT recommend non regulated LiPo or Li-Ion packs.
