RE: rx battery
I wasn't arguing with you Jonde, just pointing out that that actual voltage that the receiver sees with an A123 isn't much different than with a 6v NiCd. A recurring error is to think that the nominal volt rating of the pack is what it actually puts out, when it actually puts out a good bit more when fully charged. So I have trouble understanding why a given voltage is fine from one battery chemistry, but potentially harmful from another one.
