Tamiya Panther g
#4
Darryl Tamiya uses a 5mm screw where as heng long uses a 3mm screw, also there is a 4.25mm difference in the sleeve that the screw secures the drive shaft to; tamiya center collar is flush with the inside drive sprocket face, heng long is recessed 4.25mm from the inside face of the drive sprocket. and the obvious is the 1 flat and 2 flats on the shafts. but the track is usable on the tamiya sprocket. this should help answers your question.
