hi guys i have noticed that on my xmod when i drive it fast, itll go crazy when i turn it not liek crazy turning just real light to keep it on a straight track. now, if i put the remote on fast, and go as fast as possible it just starts spinning around going crazy. COMPLETELY crazy. could this be the tired? im doin this on wood floor and their the stock tires? i also took it outside and it is not as bad on the concrete but still spins aroudn alot when turning. i think it might be the tires but im really not sure. i had a skyline before that ran fine with stock tires but now that i got the white supra, its been actin up liek this since the start. i appreciate the support thanks
