Sorry guys, do you mean 57 is 0.057" drill bit?
Ran it today, and sadly struggled a little, defintiely with running stock pistons!! Got a bit better when I put my tamiya dampers on it (I don't have the correct drill sizes) although it still didn't like jumps!!
Reasonably happy though, it was similar speed to the 501x I run by the end of the day, not a mile off anyway, and I think will get better once I get the dampers sorted!
