I can conclusively report the wheels have as much detail on the rear side as the (1975) Tamiya wheels
and less on the front as well
Comparison: in MM not including axle stubs
Dia 17.33 17.34
Width 5.98 5.86
Dia 11.96 11.89
Width 5.64 5.57
Dia 15.23 15.25
Width 6.86 6.64
Not much in it, visually.
The Track is a different matter, some 40+ years seperate the kits, I like how the dragons look, with seperate rubber bits, they should be easier to paint, letts see how they build though.
Width 10.97 10.53
Pitch* 4.378 3.852
*Pitch defined as the length of 1 track shoe, (5 measured divided by 5).
Visually the Sprockets look a similar level of detail, but the Dragon sprocket has much finer width teeth, & curiously does fit the Tamiya track, but not vice-versa.
The Tamiya track wouldn't be long enough for the M752 though.
The Dragon Idlers are missing 4 bolts for the centre cap.
The Roadwheels are another matter, though visually a similar size, the Dragon wheels have poorly defined centre bolts & are missing the outer rim rivets entirely, but does have a sharply defined raised rim separating the rubber from the wheel.
The Tamiya Roadwheels, for 1975, have sharply defined bolts & rivets, but would require serious fettling to fit the Dragon axles.
Both sets of wheels have centre bosses that are not tall enough.
I'll wait for my refs to arrive before I pronounce further, and posting some decent photos would be welcome.
