His Minicon port is under the helicopter - the best use for an add-on in this mode is to attach him as a spinning blade weapon to a larger toy's forearm or shoulder. When pegged onto the back of Hotshot he can be bent over the back of the car providing Hotshot with a rotor blade behind him !
TF: Fold the cab forward to become the lower legs. Fold the tail under the helicopter to become the chest. The cylinders to the side of the helicopter swing down to become the arms.
In robot mode he's pretty much a Micromaster style TF, although he earns points for the separating legs which are jointed independently at the hip & knee and rotor blades that form the helipack that can be raised above his head. His arms also move but only at the shoulders.
In Japan Jolt retained his name and was available with Hotrod (Hot Shot) as MC-03 or both also appeared in MS-01 with the Air Defence Team.
In Japan Powerlinx Jolt is called Sparklift and is available with Hotrod supermode in MC-13
This set looks really nice, I'd have liked one.
