Static power through the Powerbox is 5.75 volts. Under a load, the voltage is 5.5 volts. When I read the comments on a "fresh charged Li Ion", I thought you guys were joking. Since the Powerbox regulates the juice to the servos, your "fresh charged batteries" will never be a factor.

You are thinking back to the Nimh days when we did not use regulators. The servo jitter as it is called is a phenomena that has been around since the 8411 came out. It's the servo hunting for neutral...and pretty normal on IMAC birds. I see 8611As on many large jets doing the jitter dance quite often. It's no big deal.

If it starts jittering, just feed in a pinch of up elevator and watch it stop instantly (on the ground). In the air, it will be just fine.
