I did one ZDZ 80 for a friend of mine, another friend got one done by the guys at RC Showcase. I followed where RC Showcase did theirs - right on the 'flat-spot' of the gold ZDZ 80 'tag' on the side of the crankcase. By "flat-spot" I mean that area of the tag where there's no text.... worked great, smokes like crazy.

Again, some dis-assembly required, and be careful where the chips fall!
