      yay days off doing stuff

      well assuming that the pics have worked you will see that there have been some changes firstly its not hdpe but polycarb that would be because i made such a complete screw up of the hdpe i needed to start fresh and i found that the poly was easyer to work with and it looks a little bit different.

      i weighed this as it stands and its up at 945 grams when i added everything else to it i came to 1.405.... closer than i would have liked also you will notice that its atm wonkier than a tower in italy hopefully once things go on it will straighten out a bit

      but yay it's finally coming together though i have bitten the bullet and ordered a smaller battery for it same power but inly 3 cells should save about 50 grams and will hopefully get me underweight

          well that was a massive kick in the spuds got the last of the soldering done...all wired in and ready to go powers up ok first attempt to drive in a straight line with everything onboard and it shoots off at full throttle and slams into the wall and refuses to respond to control inputs (thank god for removable links) im thinking im getting interference from having too much to close together 6 motors might be too much for it may have to go back to drawing board for this one
          one step forward 2 steps back

                im not quitting but im thinking i might have to redesign the entire thing as i still want 6 wheel drive but i fear that the interferance caused by 6 motors is enough to send something mental might remove 2 and see how it behaves

                    Retry the set up with the rx and the esc outside the bot.

                            The milly ann bug comment was meant as a fun one, hinting that you could add a 'cart' behind your bot to house the electronics.

                            I personally never experienced interference originating from my motors while using a 2.4ghz tx/rx.
                            I actually believed it to be an impossibility.

                              i did too thats why i wasent originally worried but after that test run i think its safe to say that a redesign is on the cards might look at a belt drive and only run 2 motors

                                ok folks first the good news after a plea for help about mixing its all been sorted..ish needs tweaking but thank you shakey
                                after getting that into what i thought was a drivable state i decided to film exactly what is wrong with my bot in the hope that someone can watching it and point out the obvious thing that i am missing somewhere:

                                couple of this firstly you will need to skip forward as dumbass me forgot to get it in the camera and secondly the wheel escaping was my own ineptitude and not the technologies
                                please feel free to shout out any observations and yes the wiring is a mess and i haven't made a rear or top for it yet
