Go to Post When there appears to be something stupid wrong with a game (HPs outscoring robots, unreliable loading, autonomous that accomplishes nothing) I shouldn't complain about it. I should see it as a challenge to exploit! - Chris is me [more]

This only has an effect while ramping up to full speed and during speed control (depending on the application) - it wouldn't decelerate a drive train. What will is a different gear ratio.

Don't you hate it when people don't believe the "numbers"

Phil.
Hate it? No, but it makes me laugh when the answer is right there and they ignore it.

Re: Motors not running full speed?

I second a re-look at the code. I know in 2010 we switched to labview and were using jags for our drive motors and the robot was noticeably slower than last years robot. In labview the code was set on Vic's and when in the code they were switched, instant return of power. So even though you've checked the code, a second look couldn't hurt
