if the gearing wont let you use 7000 rpm then set it to run the motor at 7500 and adjust the timing to 41. this is just an example (not a great one but for demonstration). a better example would be if the track needed 10000 rpm. maybe 52 degrees of timing and gear to 10000 rpm.
67 volts? did I see over 400 amps? wow, I get less than 200 amps on a 17.5 at 8+ volts but I never ran that low of voltage.
On small tracks, I find corner speeds for hairpin turns can be as low as 3000-3500 rpm, and accelerating out of them with peak around 7000 rpm gives very good exit speed when you gear correctly.
In response to your question about 67 volts, the scaling on the power run fitting module defaults to a different unit of measure which is why you see the high values. The graph showing torque displays correctly when you adjust the settings.
