    Back in November 2019 I started buying stuff to have everything in hand for Christmas week and the Monster Motos I had ordered never made it. I had wanted to have everything in hand prior to starting work on the project and for some reason I shelved the project.

    I have now re ordered the Monster Motos and still awaiting delivery, however I will be starting the frame tonight and also have everything ready so that they will eventually make it from China, it will be a matter of just connecting the boards and get it all configured and fine-tuned.


    The rig will be running x3 50:1 PGSaw motors and frame will be built from 20mmx20mm and 50mmx30mm metal hollow sections.

    Mainly it will be built based on DOF reality H3 design, however just as a base as it will have ‘some’ modifications


    I still need to figure out how to get the seat and steering to be adjustable (easily) for my 7 year old, without sacrificing stability…… but I guess ill figure that out as I go along


    I will keep this thread updated with all the progress…. But it might take a while, as free time isn’t on my side

    Let the fun begin!

    3DOF, DC motor, JRK
    The CTC is way too big, 40-60mm is more likely about right, depending on the intended design.

    That's more like it :)
    seems i have a bit of lee way where to play around at least. I will obviously try and shorten the ctc as much as possible.

    The Universal joint is from a Land Rover defender and i replaced the bearings with new ones, for peace of mind. I guess its an over kill :)
    Just need to support it a bit more as its with diagonal supports just to be safe.
