HI Artyy
Regarding the throttle I may not be of much help as I think these drives now have no com/port for throttle but I am not sure, maybe they do. My motor was one of the first ones in North America, and actually when I received the motor the batteries were still in developement. I do remember trying with no luck to connect a third party throttle direct to the motor/controller and it did not work as the whole com/port thing had to be inline with power coming from battery to the throttle. Not sure if its still like this so I would be interested aslo if things have changed. Good luck with your plans Artyy keep us posted.
