After I converted my Vsett to twist throttle by adding the Julet 3 pin female connector in place of the hall effect sensor, my son really wanted one for his Zero 10x. The throttle controller display of the Vsett and the Zero 10x QS-S4 was very similar and uses the same Hall Effect 49E series sensor.
Here is the conversion process I did to convert the QS-S4 thumb throttle to a twist throttle using the Julet 3 pin female plug. I believe converting the standard QS-S4 to adapt the Julet 3 pin female connector will be very similar. Once the Julet connector is installed, the QS-S4 can be used with may other throttle mechanism.
Observation of QS-S4 with finger vs QS-S4 with Thumb:
I noticed the factory QS-S4 pre-programmed for the thumb throttle has a wider and more granular response to the thumb throttle as well as the twist throttle once modified with the Julet connector. The factory QS-S4 with the finger throttle must not be programmed to take advantage of the wider throw of the thumb throttle and is noticeable once converted, as it would hit full throttle prior to the thumb or twist hitting the max mechanical limit.
Warning:
This video demonstrate that converting to twist by installing the Julet 3 pin female connector is possible. The modification requires some soldering skills and technical knowledge of the electronic components and the correct method for handing these electro static sensitive components. I am not endorsing or suggesting anyone try this out. This is for educational purpose and any disassembly may void your manufacturer's warranty.
