Some more pics of the end bell & can.
Epic is a Trinity based motor ( can & endbell is designed & made by Trinity)
Looks to have epoxied windings but drill balanced. Trinity mostly used epoxy balancing mostly on their hand wound mod motors . A outside pic of the can might help. Could be a old speed gems motor which is a budget modified motor.
Brushes are almost a vintage part now since brushless is so cheap to set up. I found these on the bay. You would want a standard brush ( Not lay down, Timed or others)
Standard brushes are interchangeable just the compounds are different. Best all round brush I used was the GM 03 Racing brush but these are good too.Just double check that these aren't lay down if you buy them.
