Hi @FerdiCakmak,
With the help of the BlHeli developer, we were able to generate a version of the BlHeli_S firmware with the damped light setting disabled. However, this did not solve the behavior, and resulted in more violent braking force upon direction reversal than before. This was likely due to the interaction between BlHeli’s lack of a dead zone and running it bidirectionally without braking. BlHeli was not intended to be run in this way, and unfortunately it would take a more fundamental re-working of the firmware to make this work well- an entirely new firmware would likely need to be developed.
The active braking only has noticeable side effects when the thruster is run in air, and with specific types of power supplies. Underwater and especially with a battery, there is no issue, therefore we do not see a need to develop an entirely new firmware at this time.
If any possible extremely short and small voltage spikes are a concern for your particularly sensitive equipment, I recommend using either a different ESC or or adding a power filter.
