Disappointing to start a class, only to have the motor be updated or be replaced weeks or months later.
That is is a difficult thing. Manufacturers do whatever they want. Looking at the Speed Passion 13.5 turns brushless motor wel used in many stock competitions it was a disaster with at the end 6 different versions, all with a different performance but sold with as same part number.
Having experience with the N21-5T (in the same line as the Sturm/N12T1) I can tell you there are many differences in timings between production series but on the track all perform the same. The only difference is that the one needs a different gearing than the other and that is something some drivers do not understand.
Also due the lower power the clutch is becomming more important. Without support to those people who do not understand this they still will face a unsatisfied performance...
