Motors with twisted comm are to be used only for small tracks. The gearing should be between 7.5 and 9.5 for the 12x1 HT, usually 5 teeth lower than with the usual motors / same winds. They have less power, but much more RPM. Counterpart is that they do heats a LOT, and that's why they're not suited for anything else than short tracks. If you have a look at the armature, you'll see no soldering, because of the heat.
The others V2 should be geared down 1/2 teeth compared to the usual motors/same wings.
They are not faster than the other ones, but the brushes last longer.
However, I prefer by far my standup motors with CS brushes. Got 50 runs out of em brushes, got power, not fearing to burn the comm, skim the comm about every 10/15 runs... Best of both worlds IMHO.
