Hi Paul, Im trying to build to spec but I make mods as I progress. Ive just Googled 24v motors and theres pages of them or am I missing something. This is my first attempt at something this big ! At what stage are you? I met Ray McM at MEX Harrogate last year and have spoken to him twice and hes been very helpful after I bought a set of laser cut couplig rod which turned out to be a load of tosh This also my first go on Forum (I,m not good on computers) I just hope I ve pressed the right keys this time. Regards Terry
