use Digikey P6305-ND or P5417-ND. both are 470 uF electrolytics, axial leads (that is, leads sticking out opposite ends) and are 16 mm long and 8 mm in diameter. in other words, they're the right value and they'll fit. F. (...) (27 years ago, 13-Apr-99, to lugnet.robotics.handyboard)

I'd go for the Coke can idea. Sounds like a surer shot. I thought init_expbd_servos(x), where x = integer from 0 to 5, was used to initialize the servos individually. Stupid me.
