### Servo accuracy

Greets. I'v built a little stand out of wood, marked the angles from 0 to 180 degrees, and testing servos on it. I'm testing them on the MK-65 controller (similar to kondo setting the offset positions, range is from -900 to 900), so the hi-tec servo results are: 450 points = 45 degrees, -450 points = -44-46 degrees, other servos results are around 485 = 45 degrees, 430-500 = -45 degrees (haven't tried the kondo servos though). So what should I do with my servos to get same results as hi-tec? The problem is actually serious - my bot is straight in the standing position, but when I make him sitdown, I should send equal values to my mirror servos (simmetrical position), but I get him sitting all wrong, the legs aren't simmetrical. That's my main problem.

Any thoughts?

Thx.
