You're probably sending that motor to an early grave and shortening your flight times running that motor at 17A. The HK 5X3 data looks consistent with that for a high price motor in the same class, the AXI 2208/20. That motor has KV of 1830 and a 16 A limit. According to the Adam_One calculator, it's turning near 18600 RPM with a 5X3 and 3S, while drawing about 6 A. The Watts to heat curve goes up to 40 at 17A in.

Using a 6X3 or 6X4 might get the current down to 10-13A and spare the motor.
