Here's just a quick mod to ROTF Bruticus w/crossfire appendage set. Transform your Legend class Ravage into its "Flight re-entry" mode, place 2 tiny rare earth magnets on his lower or upper kneejoints. Then place 2 more magnets that will line up with the Ravage mags, on the Bruticus backpack. Voila!!! Instant quick mod that looks pretty cool! Almost like Bruticus has a spine, HaHa! Ravage doesn't lose any articulation (knee joints are fixed) and still transforms just fine. Hope this helps some......Let me know what you guys think?
