On this new model the speed sensor picks up the sprocket gaps or brake disc bolts on a bike.
I am not sure where to mount it on my kit,any ideas,its a live axle,so I am a bit limited as to where I can put it,and there was me thinking it would be easy as I dont have to worry about magnets.I could make up some kind of toothed wheel like for ignition,just not sure where to put it.

mounted mine on the diff flange,araldited the magnets on,you have to do some calculations to take into account diff ratio but it worked in the end

i have the rx1n model, mounted 4 magnets on the prop on the gearbox side, the sensor was then mounted to the gearbox so the gap is always the same. done over 1000miles so far and still reads correct. to get the speed corect i had to divide the wheel circumference by the diff ratio.
hope this helps

a sprocket gap shirley equates to a magnet?its just a make and break of a magnetic field,as for the mounting,mine is a bracket bolted to the diff/casing mounting ring and looks down at the flange
