All of these posts are very hard to read! Here are the things (I think) other people are thinking:

1: The battery is dead.
2: The code is bad.
3: The transmissions are bad.

More detail:

1: Pretty self-explainatory. Less power in the battery, less power in the motors. Charge it overnight, try again.

2: If this is the default code, this shouldn't be the case. If the code HAS been changed, make sure that the PWM value is near either one of the limits while testing. That is, the PWM value is being set to near 255 or 0. The pwm_XX variables are the variables that control the speed of the motors. Replace the XX with any number, corresponding to the PWM output you are trying to change, 01 for PWM 1, 10 for PWM 10, and so on. Tell me if you need more description than this. I can probably help on the programming.

3: Grinding noises usually indicate mechanical failiure, but buzzing noises are normal because of the way Victor speed controllers work. Make sure you put the transmissions together right. I'm not a mechanic by any means, so I probably am not any help in that field.

Hope this helps...
