Since the regenerative braking feature built into the circuit created issues for some devices, Hitec had to develop a plug in device "PAD" (Power Absorbing Device) that will give the current somewhere to go if you are not just using a battery for power which can take the input. Regulators and Batt share devices had issues with this so this is the cause of the delay in releasing the product. The "PAD's" are on their way so these servos will be shipping to the dealers shortly.
Yes, they are fine with a one PAD installed in any open channel.
The circuit design creates incredible power and draws 1/3 that of other servos. The torque rating is actually usable torque as the servos do not slow down until slightly before they reach stall. No other servos do this, they all get bogged down well below the stall torque. I don't think regenerative braking is a bad thing but it does create an issue for devices that cannot absorb it. In fact the circuit designer Alan Cocconi was involved with some of the first electric vehicles and his circuit design is the current technology used in cars
