I didnt do any paintwork to the "color" areas of him as i didnt want to mess with them, they are perfectly good standard so i didnt feel the need to touch them plus i didnt want to mess up the flame job.
Here's some close ups of the removable bits and some explination after:
These are the arms that connect the rear wheels to the legs, these fold up and snap into the bakc of the leg normally but the wheels get in the way of poseability. By cutting a slot in the hinge that connects around the metal pin on the leg i can now remove these at that point. Note i cut the slot in that spot specifically so that when in truck mode the slot is aimed down, the arms generally pull tight in truck mode but this way they wont "fall" off since they must go up to come off in that mode.
These are the flat fold up sections on the forearms that fold down into the rear wheel section in truck mode, they are nessecary to lock the transformation together in truck mode, but add unwanted girth to his forearms which are already boxy as crap. I did much the same thing i did with the leg struts here, although it required alot more effort and more time being careful as to not crack or break the plastic. This plastic is morebrittle ABS type plastics not the softer PVC of the wheel arms. Also the "pipe" in the back of the arm where this fold up section connects is hollow plastic and can be broken if you pull to hard on it, there is a screw setup on the arms that would allow you to remove this fold up piece without cutting it but it requires dissassembling the arms almost entirely below the elbow. This way i can snap the extra part on and off at my leisure.
Hope that helps.
As for brawl hes worth getting, the best decpticon, and frankly makes you wish they made all the big decepticons in leader scale the way they are supposed to be. Though i expereinced the same problem with the left tread not wanting to snap into the tank side correctly cause of the arm, i dont know why it does it i can't find the part that is causing it cause the right one goes on fine, friend of mine who has him says he has no problem so i dont know what the deal is.
