This worked fine on both our test-bot and the final robot.

AndyMark 8"... check
3-axis Joystick ... check
"twist" for rotation ... check
PWM ... check
no wheelspeed feedback ... check
rotation "scaled down" ... check
only difference is wheels are connected to toughbox (12.75:1) transmissions via sprocket and chain.
What kind of curve-shaping did you do on your joystick outputs before feeding them into your wheel-command-calculation algorithm ?
