theres a shop in Adelaide called "Battery Packs Australia".. he is a battery distributor who works out a shed @ his house...
He will make/sell battery packs for anything you can think of except automotive batteries, and he is damn cheap and extremely good..look around locally for other similar distributors/wholesalers like "Olympic batteries". They will do the same, but at a slightly higher price than batt pack aus.
NTC3, FYI: 4x disposable AA's @1.5v = 6volts
4x rechargable AA @1.2V = 4.8volts (all rechargable AA's are 1.2v)
5x rechargable AA pack @ 1.2v = 6volts..
this is why, whenever you upgrade to rechargable (either nicad or nimh) it is important to get a 5cell pack made up, otherwise all your radio gear runs on lower voltage than normal + all your servos work slower + range may be affected also.
If you buy locally,a pack shape like the red one on the left will fit straight into the tc3 receiver slot in the chassis. My mate had a pack that shape made for his TC3, and it works great. the top battery sat "just" above the chassis, so its all nice n low still..
ar.. sounds good, I'll pop down to hobbyco in the city somtimes. I live in Sydney Oblivion, so I dont think I can get to that place you've mentioned, thanx for the heads up anyway.
I've actually bought 16 Sanyo 2300mAH rechargable battery off ebay the other day already, should get them on monday. So I would use 8 for my transmitter, and pop down to my local LHS and ask them to make a 5 pack out of the remaining ones for me
