You got it. You can apply the different plans or make up your own design after reading the plans. Which is exactly what Ed pedalcar did with the inferno. Old peddler was also working on a delta wolf or maybe a Loderunner with the wide wheels. Unfortunately his heath got to him before he finished it. You should search Sir Joey's name in the gallery as well to see his beautiful contraptions. Again he is no longer very active. So you can put any wheels and gearing you desire. The only limitations are your imagination, time and pocket book. Have fun building and we love photos. And remember grinder is your best friend of a new welder. It can erase bad welds and allow you to fix anything the is weldable.
