wheel coupler

the link above is a way of attaching rc wheels to 4mm shafts however they are coming from the other side of the world and as such postage is measured in what feels like light years so if anyone knows a uk supplier then that would be amazing

i have gotten 2 and they work brilliantly on the standard 1000 rpm motors

Why not drop the seller a question and ask if they can ship them express?

i ordered them over a week ago and they were dispatched last wednesday the thing is the last set i ordered took 8 days to arrive i dont get how these ones are taking longer
