Ahh brilliant thanks, now ordered the main construction materials, and will be ringing up a few water jet companies about the hardox weapon in a few weeks time.

And thanks Maddox10 but that site doesn't seem to have the 24v 800w version either, every where i've looked still has the 36/48v 800w motors (and the odd 1000w) but all the 24v 800w motors all say out of stock, or have been removed. I had wanted to run the 24v motor on a 8s lipo (so mild over volting) using a ragebridge. But the 36v motor is at the limits of the controller voltage so could only be run on a 9s, so will be slightly undervolted.which is why I wanted to avoid using those if could.
or am i being a bit thick, I had presumed the were the same armature with slightly different windings inside. But are they actually the same instead, and just mislabeled? with the the 24v version being just an undervolted 800w 36v motor, so would actually be a lower power (500w motor)? or was I correct in thinking it was wound differently?
