FfarquharDeveloper Got what I thought was a Hit Shell and Hit Chassis Arry and Bert in the mail today, but it turns out both chassis are from Hit however Bert's shell is a Hit while Arry's shell is a Fisher-Price. Really happy to have them at all now as I've been needing them for quite a few things. Similarities and Differences Both have Arry/Bert in the center spot. Colors are different. -- Hit has a Richer Yellow and more Green base shell. -- Fisher-Price has a more Brown base shell and a paler yellow. Fisher-Price has additional structural support inside + a bigger metal weight
FfarquharDeveloper No real difference without the shells, Bert's is just slower probably due to Battery Corrosion.
