I'm very familiar with the TC-9 motors using .75" slugs and 1" slugs but I've heard a few people mention this mysterious TC-9+. I have never seen anything on TC's website (new and old) that mentions a TC-9+.
For a reference, a TC-9 with two .75" slugs would obviously have 1.5" of magnet height and a TC-9 with two 1" slugs would have 2". The 3HP has 2.25" and the 3HP+ (aka 3LM) has 3". Where would the so-called TC-9+ fit in?
Is this a misnomer? Please show me what you think it is.
