Greetings,
Yes, you would have charging problems with a Y cord. At this point I think it would take very little weight on the tail and that would be the easiest way to go.
BTW, a 500mah nicad is kind of behind the times as far as batteries go. A modern Nimh of the same size will be about 1600mah..... fly all day without recharging.
AAA's are lighter and smaller than AA's.
Best of luck!
