I have an old Rustler with the mechanical speed control and a receiver with BEC. (2015 I think)
Will the speed control shut down if the battery gets to low? (no receiver battery)
If I convert this to a XL5 will I need a receive battery? Thanks; Don
Yes, the speed control will stop functioning wherever it is at (full throttle, for instance) if the receiver looses power.
Converting to an XL5 will eliminate the need for a receiver battery due to the new ESC itself powering the receiver.
Whatever it is I just typed... could be wrong.
