Mini Spool 8.75 questions?

I rarely notice any tire squeeling running a spool on mine. Every now and then I can hear a faint "chirpping" when turning a corner. When turning, your left and right wheels are going to fight each other (one will try to drag, one won't). The outside wheel wants to go fast and the inside wants to go slow which causes higher stresses. This is what COULD break the axles. Doesn't mean it will. It may or may not happen to you. I just try to take wide turns with mine to keep from dragging too much. For the price and weight loss going to a spool, I have no regrets as of yet not having a sure grip.
