LRP SPX Setup for racing.

[dagfather]

Hi.

I've got a LRP SPX esc in my Kyosho ZX5 SP (waiting for a FS).

Can you help me adjusting this for racing?
My feeling with it is that it was lacking some braking power when I drove it.
I do think the SXX has more options regarding brakes, but I have the SPX...
The engine is a NOSRAM 6,5. I was also using a front one way.

I drove the ESC with it's standard setup.

Do you think this will be a good setup?

Mode 1: Value 1 (Lipo)
Mode 2: Value 4
Mode 3: Not relevant
Mode 4: Value 4 or 5?

I'm also using a Spektrum DX3 transmitter. Perhaps there are some "hidden" secrets there that can make it even better?
