At this point I have designed a few more sizes of tire. It is clear I will need a better motor setup then what I have at the moment.


With a taller tire I need more gear ratio for sure. It might be a good idea to go brushless. The real issue is going to be ordering the right motor/esc.



Here is a look at the chassis with the tires I have been testing. I am running 1 band on the front tires and 2 bands on the rear. I see Indy Car with those tires on it. I might just
have to come up with a Indy car as well. (when i get this one done of course)




The capped tires are working really good on the concrete. I will get more tire test video as soon as I get bearings on the rear axle.
The axle size is .124" and I have ordered bearings 3 times and have yet to get a .125 ID bearing that will fit the axle properly.
So my goal now is to use a larger bearing and us a spacer to fit the axle to the bearings.
