it pretty much involves taking apart the motor and rewinding the armature with a thicker wire and less winds, all u need is enamel wire a soldering iron some fine sand paper and a screwdriver…
start by taking the end bell off the can and pulling the armature out. then you have to desolder one of the points where the wire attaches to the commutator, (try to find the point where the end and start of the wire are attached, not the points where the wire just loops over) then start unwinding, count the number of turns the motor has..should be about 70. when the motors fully unwound, get some enamel wire, sand or melt off the enamel coating so u can solder it to the commutator, solder it on then start winding…wind it as per oposite to the way you unwound it..you should only need one very long piece of wire…
I use 30 B&S guage wire which is availible from jaycar but some people use thicker guages depending on prefrence….
43 turns is as low as you can go with standard FETs in the z, anything lower will fry your FETs…so only do about 45 or 50 turns
Aparantly the x-speed motor is just the stock motor with 50T instead of 70T….
start with cheap motors so u get a feel for it without destroying expensive kyosho products..
