I have the v2 19T, and I have to say, although it is not the fastest motor, it is surely a great motor out of the box.
Overall, its the best practice motor I have ever had because it allows me to try a fair range of gearing combinations, long lasting brushes and a comm. that won't quit. (When TO said 30 runs, they MEAN 30 RUNS!)
The maintainance Vs performance ratio is the best amongst the motors I have tried.
