Calibrating speed controllers and joysticks

[thedillybar]

Do we need to calibrate both the speed controllers and joysticks? I know how to calibrate the joysticks but I'm not sure how to calibrate the speed controllers.

Also, since the speed controllers have this "built-in" deadzone, we should just use this:

PWM1 = p1_y

instead of:

if p1_y>117 and p1_y<137 then skip1:
PWM1 = p1_y
skip1:

Thanks.
