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
