Great concept and overall build quality. I do believe this design seems rushed, I can already think of ways the rollers need to be supported & switching the drive belt from O rings to real belts from RC cars. Overall, good value for the price.
I love it. It works great!. One suggestion- Make the valuable speeds more pronounced . E.G, 1st gear 2nd gear 3rd gear, etc transitions
This is brilliant piece of engineering, very well made and looks like it will last, it’s runs so well and easy wheelbase changes.
Very well done guys, highly recommend and good luck with future projects
