I didn't have a Classic Inferno - their price is jacked up so ridiculously high it is insane to buy one new. However, I managed to so some simple mod with the Hot Spot from the Evac set (dirt cheap) plus a spare Combiner War Hot Spot's ladders and a 3-D printed head to create my own, staisfying Inferno - and here it is: Head shot (BHDA printed and painted silver) Bot mode with Hot Spot's ladders. Thanks to the many points of articulation on the ladder there are a lot of different poses you can do! Fire engine mode - similarly, many different ways to fold it. what I did is remove the ladder from the back of hot spot - it is held by an axle with 4.5mm diameter. It needed to be bored out to 5mm diameter in order to be put on the classic figure.
