I had a Bandai Stug but wanted the reliability and durability of a Henglong. Bought a Panzer IV and attacked it with the dremel. Surprisingly the Bandai top fitted the Henglong pretty well. only thing I hadnt allowed for was the gearboxes were too tall for the lower plate. Resolution was to hide this hence the sand bags made from milliput!
Very nice mate Ive been thinking on this conversion for a long time but using a HL Stug III on top of the Pz.IV body . Nice job you have done . Any build picts ? I converted a HL Pz.III into a Stug III buy getting one of Daves Stug III tops . But I added the Stug III gearboxes which sit lower than the standard HL ones
