I am looking to set up a reusable kit to make solar cars, wind powered cars, battery powered cars, etc. We will be using cardboard and our own supplies for the body. I just want to order a good gear set (w/ different sizes), axles, & motors that are a pretty good size to get them going fast. The reason I don't order the Solarmade kits again is that they are not that reusable and there's not a good selection of gears + the gears break down a lot.
I am at kelvin.com looking for these things but am unsure of the proper motors to order. I see a cheap bulk pack for solar cells. I have some questions if you have time to help me with them:
