Re: Servo Questions

Some R/C transmitters have a plug that allows you to test/controll the servos bypassing the RF section. This allows you to "adjust" the servo without transmitting a signal.

Re: Help with animation

Would these suit your needs, I used one of these to turn a radar scanner on a model rc offshore tug boat I built years ago. Pick your gear reduction and then vary speed with voltage. Robbe Minature gearmotors

Making a Backup copy of a DVD

I have a auto repair manual on a DVD that contains approx. 6.3 GB of information. Because of the cost of the DVD I would like to make a backup copy. I have a DVD burner but was under the impression that a standard data DVD would only hold betwenn 4 and 5 gigs. Am I out of luck on making a copy?
