The Jambo and Dementor are shorter wheel bases than the Kronos and Punisher. Punisher comes with a cap pack and skid rails on the roof which the Kronos doesn’t have. Basically all the same electronic components across all 4. So 2 short wheel base “stunt trucks” 2 longer wheel base “muggies”. Then there the Muraco and Shogun so 2 true truggy variants. Gives customers a choice of body shape in the truggy, muggy, stunt truck styles. I think it’s a great way to bring people in to the brand, I like muggies but didn’t like the Kronos body so would never buy in to it as if have to fork out on a new body straight away to be happy. But now there’s the Punisher, which has the skid rails and a shape/colour I prefer, I would buy this.
