Blender Pilot,
I will buy that explanation, with one exception.
You stated: "You mentioned that the optional Kit is Bells solution to the L1 and L3, but it's more for the L3 or L4 and it makes no sense to be installed on the L1, because the L1 has little power thus the TR can handle the job given, since there is less torque to counteract."
In our company, the L-1s and L-3s have the same engines nowdays, and thus the problem persists in the entire L series. Doomed to the wild ride if attention is not adequately applied at the appropriate times.
Good conversation! Poor design!
