Has anyone else noticed erratic behavior controlling two servos from the same receiver? I have got two servos set up, one controlling the forward set of steering wheels, and one controlling the rear ones. If I hook them both up to the same receiver on the same channel, they will hardly rotate at all, even when full steering angle is sent from the controller. If I split them to each having their own channel on the same receiver, the result is the same - if I control both inputs at the same time. If I first rotate one, then the other, both servos behave normally. The same goes when I split them across two separate receivers, set to channels 1 and 2.
Is this some interference or battery power issue?
