Blue gear slipping

[dzid26]

• Blue gear one way sprag clutch is delicate part and wears out over time
• the clutch tends to slip when torque is applied fast when the clutch is not fully loaded
• The most common condition to induce slipping is a gear upshift under load (the torque drops for a fraction of a second when the chain jumps "falls" onto the smaller gear - this shock induces the slipping)

If blue gear starts to slip (not transmitting torque), the motor accelerates to max speed and wears the clutch even more.

If anyone has this problem, I implemented and I am testing an efficient solution to protect the blue gear clutch and extend its usability possibly indefinitely.

Positive "side effects":

• Ultra "fast stop detection"
• unloading the motor during shifts
• helps to avoid blue gear damage during sudden braking

Limitation:

• will work only with loaded pedaling - may not work in throttle/cadence/cruise mode
