Questions?? Sensorless 3000KV race using low rate and capacity Lipo

In this weekend in the 3000kv race, which everybody use sensorless 3000KV motors, the guy which run in the front use GE Power 4200 25C and his car run as fast as hell, comparing myself which run SMC 4700 40C is much slower.
Then he told me to use low capacity and C rate in this kind of spec motor race is the advantage to be low consuption and the motor to be sensorless.
I think this kind of situation makes me feel so confused and unacceptable, could somebody tell me if is real and explain me why, please?

Best regards

His car is faster most likely due to:

1:motor timing
2:gearing
3:ESC setup

Your battery should be faster than his battery, all else being EQUAL.
He found a way to make his car faster.

Actually I have seen faster lap times with smaller LiPo's.

The smaller C Rating LiPo's build the heat quicker and maintains them while the higher C Rating LiPo's can't get the heat built into them quick enough during a 5-6 minute race.

If you remember that "heating" your LiPo was good for it? (As long as you wern't an idiot about it)

I've seen .03 per lap difference between a "great" 40C LiPo, and a "crappy" 25C

I agree that "heating the lipo" performs better.But has nothing to do with a sensorless motor what ever it is (lower or higher T).

In fact as myself can't believe is the reason of the heat quicker, i live in tropical weather place, that day was more than 30 Celsius with around 80% hum.
