The Jagdpanzer IV performed well, no issues. The side skirts, i think did as designed and while i didnt get any pics of them off, i did lose two (on the same side), but with the O ring attachment, no parts broke. the plastic idler wheel is holding up with metal tracks, which i had a track pin backing out and i think this might have helped in the losing of one side skirts. The shorter L48 barrel is a dream and battled great, if you are going to build a battling JagdPanzer the shorter barrel is pretty hard to beat.
