Autopsy of an old gentleman...
This motor leave me sunday, 11am. As it was a fairy tale, it stop forever after putting my F104 in pole position, while reaching the pits.
Reason for dying was the brush spring that breaks.
Not too bad for a motor I got with a FF01 in 1993....used into countless races (national in Italy as well...).
Probably some old guru can help me: this is the 3rd version I found with this can:
No balancing
Epoxy balancing
Mechanical balancing (look closer and you cna find some milling...)
Others?
