Been doin some testing with a 17.5 Ballistic motor and the Rbs/202g,
Found the lower FDR (3.9) works a lot better than a high (4.5), and zero timing on the motor.
Advancing the timing on the motor does give it more punch down low but generated too much heat, even with mild esc settings and fdr's around 4/4.5
Found these settings worked really well
track temp 14C
FDR 3.96/ zero motor timing
1-8
2-3
3-8
4-8
5-6
6-9
7-2
8-3
9-1
Motor temp after 6min racing 49c track has a medium tight infield, a fairly long straight with a medium sweeper lap time around 18sec
It had a great top speed good midrange torque a little soft at the hairpin but I think increasing the drive profile may help.
Dragonfire we changed the track and its quicker and longer
