Nice track
We race 21.5 open esc together with 17.5 no timing on a similar sized indoor carpet track (80 - 90ft straight + sweeper). Main issue with open 21.5 is getting good performance for 6 minutes. Too much timing and you'll fall off at the 4 minute mark, not enough and the 17.5's out motor us. So its a fine balance, but when you hit the sweet spot it may be a smidge faster than the 17.5 no timing setup.
For FDR, I would start somewhere between 6.0 and 6.5 and adjust from there.
For the motor, advance the endbell to the max position
For the ESC, download the new firmware release #01212stock, as the settings I'll share were run with the beta version of it.
#4 Level 7
#9 one down from the MAX timing setting
#12 one down from the MAX timing setting
#13 1 (1800 rpm start)
#14 .2 seconds for the delay
#15 3
With the above, I ran a single motor fan and was coming off the track around 150F after 6 minutes. The other settings likes brakes, etc are typically very driver specific so I didnt list them.
