that is EX02
the whole set consist of wing saber n GF conboy

Option 1: Hasbro Galaxy Convoy (RM300) + Hasbro Wing Saber (RM150)
Option 2: Takara Galaxy Convoy (RM350-RM380) + Takara Sonic Bomber (RM220-RM250)
Option 3: EX-02 (RM600-RM800)

I dont have pics at the moment, but the mechanism in question is the Super mode wing extension connection:
1. in Takara's GC01 and EX02 OP, the wing extensions are connected to the main back part of the truck (the sections with the back wheels) by pins (metal rods inserted between holes, kinda like your door hinges)
2. in Hasbro's OP and Galaxy Force OP, the wing extensions are snapped onto the back part of the truck. This is due to the packaging for Hasbro's OP, where the wing extensions are tied to the inner side of the box, a space-saving measure i suppose Once you've untied the OP from his box, all you have to do is snap the wing extensions to the truck's back part. easy and the snap joints is pretty tight, so no worries unless you snap it in and out VERY often (unlikely and unnecessary, haha)

IMHO, no problems with hasbro's snap on extensions. When it comes to decision between Takara and Hasbro, u only need to consider:
1. ur budget
2. colour scheme that u prefer

the pin/snap doesnt make a difference at all

hope that helps
