I'll try

The torque control is a calibrated current limiter, start with 5 and you'll see where on the track it takes the power away.
At 9 you may not feel it at all but it's still working in the backround.

You can also use it to get longer run times.

Set it the same way you would set a slipper clutch and go up from there until you get what you want.

When your rotor get hot it loses some magnetism, that makes the KV's go up.
If you look at the KV you get from the test (from time to time) you can get an idea how your motor is holding up to the heat.

The punch control is a throttle delay so have that off when your trying to set the torque limiter, you'll get a better feel for whats happening.
