At my track we are going to start running foam tires in the 19t class and I was wondering if you really needed to cut the tires down to racing diameter just for practice. I'm just looking to get some time in on foam tires so I can work on driving with them and getting my car set up.
Another thing I'm looking to figure out is how to figure out your roll out with foam tires. To figure out your final drive you do SPUR/PINION * 2.5. But with foams you have to include your tire diameter because it changes over time. So I'm wondering if anyone knows how to do that and would share it with me?
One more thing, but this is for my radio set up. I have a Futaba 3PJS, does anyone have any ideas what I should change from going from rubber to foam tires? I know I should probably change my steering exponential if I feel like it. But what about the thottle curve and stuff? Do I need to change that at all? Thanks for any input on all my questions
