RE: Batteries
I'm skeptical too. It MAY be that things in Thailand are different, but I doubt that they're that much different.
Buying a radio "set" almost anywhere else means that you get a transmitter, a receiver on the same channel (come with the crystals), three or four servos, a switch harness, transmitter and receiver battery packs and the charger for both, a servo extension, frequency flag, transmitter channel pin, plus a servo tray and all the mounting hardware - screws, grommets, rubber inserts, servo arms.
By the way, the Futaba 6EXA with all this stuff can be bought in my local hobby shop for $170 U.S.
NiCD's do not have to be "drained" between charges.
