If it's a 4-cell nicad pack, then it's acting like it has a dead cell. I'd strongly recommend dumping it.

I wouldn't. It measures like there's a dead cell. "Fully" discharged voltage should be 4.4v. If it's just idling (doing no work), the pack should stay in the green longer than 90 minutes. Full charge voltage should be much more than
4.19v. Dr.1 Driver "There's a Hun in the sun!"- Vote on answer

Nope, that voltage suggests that there's a dead cell in that 4-cell pack. Take your pick; pay $20 for a new pack and the time it takes to buy it, or $200 for a new airplane and the many hours it takes to build a new one.

That's a bad battery. After a full charge, using Hobbico voltmeter, it should be at least 5.40 under load. I agree, it sounds like a dead cell. Heraus mit ihm!
