1st Question: My tire foams came out of the tire. I thought the tires were glued onto the rims. I was doing some high speed passes when it happened. My question is should i buy new foams and cut them and re-glue them to the rim? or is there any easier way to resolve the problem. money isnt really an issue.

2nd Question: My throttle sticks or something. When i give it throttle the RPM's rise then when i let the throttle off the RPM's stay so it has the same power to the ground as when i was giving it throttle when im trying to slow down. So to slow down i have to hit the brakes. is that normal, or something to do with the throttle linkage, or is it the tune? The reciever was getting low on batteries.

Thank you all.
