Kenny's tracks and sprockets showed up today.   William (Pattoncommander) you are correct, these tracks are wider so are the sprockets.   The standard length M2 screw is not long enough.   I have had to order longer screws.   They look great.    Photos and video will be coming.    The latest update:  YHRs DBRC3 with Benedini,    Phil's new speaker for sound,   custom made barrel, Kenny Kong tracks and weathering.
