Thanks John. I appreciate your comments. I understand and agree with most of what you say, but I still find it strange that Futaba 6-channel 2.4 radios are sold with AA batteries. According to Tower Hobbies, if one want to use NiCas in these radios, one must first acquire a new "battery door" from Futaba as well as a charger that requires "soldering on the correct charger plug". It would seem that 6+ channel radios would, at the least, come equipped to accommodate NiCa batteries. I understand that various uses require different servos and battery packs, but to sell radios not ready for NiCas seems almost irresponsible. People new to the hobby could well decide that using AAs in RC aircraft is normal and acceptable. If 2.4 is the way to go (and I agree that it is), then it is more imperative that radios must be equipped to accept NiCas without additional modifications. Gary
