Re: Digital Servo Holding position after disable

Assuming the above is correct, if you add a spring load sufficient to overcome the servo, all you'll do is prevent the servo from moving and possibly burn out the motor.
This is correct for the Hitec digital servos. At this point we've solved our problem by buying a Savox servo, so this thread should now mostly be seen as informative for anyone that does/doesn't want a servo that will hold its last commanded position after it's lost signal. I need to test tomorrow if the hitec holds position even in Disabled, because I'm sure that would be a fascinating feature to some teams. For instance, IF it holds position, it means who716 could have gotten a hitec programmer and set his brake position as failsafe, and the brake would automatically engage at the end of the match.
