Faulhaber germany told me they make any spec i want
also i advise the 6volt if you need one , way more speedy power punchy then a 12volt one , thats way slower
the spec sheet is one thing , but ive walked away from it , on the field you see its allways a tad different...
that being said , the 9volt version is not on the standard list of 1piece sales
