1.44	Beta	06/01/25	Cobra 8 and 10 only Bug Fix – Torque Limit Motor Test: Bug prevented the motor test from being completed. Fix allows the test to be completed so torque limit can be enabled. Bug Fix – Aux wire Max Power Adjustment: Bug caused braking to be affected when adjusting max power. Now braking is not affected by adjustments to max power via the aux wire. Added “Fan Always On” feature: When enabled, the ESC cooling fan will run constantly. When unchecked, the fan will be thermally controlled, only turning on when ESC temp exceed ~140° F. Data Log Improvement: Improved accuracy of battery voltage in data logging. Improved braking Braking strength has been icreased high RPM, brake should be stronger at higher speeds.
1.42	Production	04/09/25	Cobra 5 only Increased motor drive frequency: Results in smoother throttle operation and less stress on the ESC during high current spikes. Added dynamic braking frequency: Improves overall brake strength and reduces stress on ESC during hard braking.
